hi all i had to replace my fuse box the one i found was a lil defferent but the part numbers was the same although on the one i took out it had the part number repeatd twice small where the one i put in had the same number but in big print and i think it was out the mk2 everything went in ok and every think still works just wondering if it cause any problems as i replacedit trying to fix a over heating problem but the car is behaving the same way thanks
-
if the plugs all fit the same then it'll be fine. what exactly are the symptoms?
-
yeah thay all fit in right so thats ok basically it gets up to 3/4 on the temp gauge after about ten mins fan does kick in sumtimes it gets right up to max also when i got the car it had after market gauges in the centre oil and water ones wich also read max any ideas?
-
also forgot to add that its had new temp sender for the dails from vw new thermostat new fan swich new water pump new expansion bottle and cap and head gasket done system flush vw coolent no air lock but have noticed the water looks a lil light brown?what eles could this be?thanks
-
ok, id start by checking the sensor for the dash gauge, it should be a black collar one with a red/yel wire. there is a coolant guide in the mk2 maintenance + info section, worth a read :)
-
yeah sory thats the one thats been done already mate
-
http://www.golfgtiforum.co.uk/index.php?topic=72160.0 its the one with the blue ring around i have changed
-
also its jh code could the oil cooler be at fault?also only cold air comein from the heater main vents but the small ones just above it are warm?heater matrix maybe?if so are thay the same for both left and right had drive cars as mine is a left hand drive
-
thats how the heaters are supposed to be!
oil cooler wont be causing it, had the one on my mk2 completly bypassed and engine temps wernt really effected. i suspect a wiring fault on it somewhere, just going to have to go over the sensor wires and earths with a fine tooth comb
-
will do and report back :smiley:thanks
-
right checkd all wirein also took dials out is the earth wire in the white plug that plugs into the back of the dials?if so that was ok also flushd coolent out and made sure no airlock also when i was putin my dash back the green light for the indicators was on faint and the indicators themselfs wasnt workin until i startd the engine then the light went out and the indicators workd!what would of that been?
-
the earth is in the white plug on the bottom of the clocks aye. the other faults suggest you have some wirign problem behind the dash, maybe check over all the fuses while you're back there?
-
the lights are working fine for sum reason still overheatin tho :cry:also when i get up to speed say 70/80 it cools down to just over the half way mark
-
hmm, if its fine when the car is driving along then there probably isnt anything wrong with the coolant sensor, i suspect maybe the rad fan isnt cutting in soon enough, or for long enough. feel the passenger side of the rad when temp gets to 3/4 and see if its nice and hot, if its cool then that would suggest rad is partially blocked. also disconnect the rad fan thermoswitch and bridge the red wire to the other wire(s) and the fan should run.
also when the engine is cold, take the header tank cap off and rev he engine, you should see a good stream of coolant ut of the thin hose to the top ofthe eader tank. if not the rad or pipe is blocked or the water pump is buggered
-
fan does cum on when gauge at 3/4 of the way pipe isnt blockd as water does cum thru nice dont think rad is blockd but iam on my way to get a new water pumpas the one in it was new but over winter trying to fix this the water in the pipes was frozen which i didnt know and tryd to start it and the belt snapd i wonder as the water would have been frozen around the pump and mayb it tryd to spin as i startd it up and broke mayb?
-
oh and thanks for all ya help so far jonny :smiley:
-
yeah that sounds like a plan dude :)
-
got water pump will fit 2moz iam really thinkin bout swapin out the engine my daily is a mk4 1.8T :evil:
-
ok when iam driveing along now its reading just over half but when i stop it cliams very fast to near the max i have testd the fan by brigein it and that works would it be the fan swich mayb?it was runin good all day just over half until i noticed that the pipe for the water pump wasnt on right and tryin to put it back on lost all coolent after puting new coolent in today its been runing hoter 3/4 and now even max when in traffic so mayb fan swich?also have noticed that the water is sort of brown again and the engine had a proper good flush 3 days ago any ideas?iam geting close to seting it on fire now! :cry:
-
if the fan doesnt cut in when temp gets over 3/4 then yeah id say its the sensor, or the rad is blocked. if you feel the side of the rad where the sensor is, once gauge gets to 3/4 it should be really hot. if its cool, then you arnt getting good coolant flow, either due to rad blockage or weak waterpump.
could test for a fan issue by running the engine up till it gets to 3/4 then manually bridging the fan. if the temp is maintained between 1/2 and 3/4 then you can be reasonably sure you need a new fan switch. if temp still goes up then you know issue is elsewhere
-
ok run the car with the fan briged and it stayd at just abit over half so got a new fan swich and run the car from cold with new swich fitted it took its time to get up 2 temp when it got to 3/4 guess what no fan!so i left it runing and it just got to the start of the max line and it kicked in for 20 secs wich made it cum down to 3/4 what should i try now other than a can of petrol! :evil:thanks for ya time and input jonny also the rad was hot and seemd ok
-
ok since bridging the fan kept the temps down to where you want to see them, then it seems the issue is with coolant flow to the far end of the rad, or maybe you have a problem with the stat not opening enough or when it should. does the car have an mfa oil temp you can check to ensure the engine really is getting as hot as the dash gauge seems to think?
have you replaced the pump yet? I wonder if the frozen coolant has damaged the stat somehow if not the pump...
-
no mfa new stat in one of them upgrade ones and i did test it b4 it went in and new water pump in and seems to run a nice flow of water back in to the tank?and stat seems to open when temp gets up to half way
-
right just got new rad and vw coolent how do i mix this 50/50?
-
what i do is tip a whole bottle of g12 into the header tank, then fill the empty bottle with water and tip that in. then get a 2nd bottle of g12, half fill the empty one, and top them both up. easy way to get 50/50 :)
-
top tip
-
update time with the new rad in the temp still gets up too 3/4 and above not too bad when drivein just over half but when not moveing goes up quik and fan is cumin on just befor max wich brings it down to 3/4 any ideas lads before i really do burn it!
-
does it smell hot when it says it hot??? any perfomance issues or anything?.... strange one this... the only time i experienced this was when the head gasket was going on an old cabby... how old is the oil btw?
-
h/g was done last year oil not very old i have noticed the water lookin a lil brownish and sum brownish lookin sand/rust looking sort of suff in the header tank?
-
i know you've just put fresh coolant in it already but if theres still signs of brown sandy water, you could do with sorting that out.... lots of flushing!!!.. especially if you have a new rad too... that brown sh*t can mank up temp senders aswell. what are the condition of the hoses like inside, brown?
-
i do flush and still it cums back?pipes all look good no sh!t inside or anything?
-
right runing car today and when drivein its just over half when stopd it gets over 3/4 near to max and fan kicks in then of and then in iam getin the oil light flash every now and again also my horn was dead and ive just got one of a mk2 but when i press it the coolent light will flash and thats every time i press the horn!clocks mayb?
-
also my golf doesnt have mfa function would these clocks fit as mine only has the clock at the bottem not the oil and other things like the one below but would thay still fit http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=230455607090&ssPageName=STRK:MEWAX:IT
-
I'm starting to wonder if your car is overheating at all?? sounds like you have a couple of electrical problems and your temp gauge is not reading correctly... also those clocks shown look like they are from a MK2... I could be mistaken. If they are then they will not be plug and play, even if they were you're car may not be wired for MFA anyway.
-
ur not the only one if i take the cap of the water bottle when the car reads 3/4 i can put my finger in there and its hot but not mega hot?

Heres a thought then, test the water temp with a thermometer, something like this or cheaper that can cope with boiling water http://cgi.ebay.co.uk/Multi-function-thermometer_W0QQitemZ190362525307QQcmdZViewItemQQptZUK_Kitchen_Accessories?hash=item2c527d9e7b (http://cgi.ebay.co.uk/Multi-function-thermometer_W0QQitemZ190362525307QQcmdZViewItemQQptZUK_Kitchen_Accessories?hash=item2c527d9e7b) you'll see then how hot she really is. with the extra info youve given its looking like minor electrical problems and most likely bad earths.. I'm currently rewiring my car, one fault being all guages read max all the time! (that doesnt justify the rewire, there were other reasons too if you see my project page. My first suggestion to you now then is to check all the earthing points in your car and make sure that they are clean and rust free, also make sure that there are no solid brown wires anywhere in the car that are not connected.
-
have already done all earths on car twice!lol what number is the coolent temp relay?think is number 18?could this be at fault?i will check temp like that good idea also anybody got a pic of there engine to check my earths i no the one on the gearbox and the one on the right hand side of the rocker?
-
thats correct, temp relay is 18, top right of the box.... it could be that. has your car got a lot of additional wiring above standard?
-
yeah its pretty messy and the relays are not clipd on to the top of the fuse box thay are hangin around lose how will i no which one it is?
-
you might wanna address the hanging relays, not good for the connections.... cant you just slide them back on to the box where they should be... dont know off the top of my head the relays white marker number but if its hanging loose, its the one with the following wires on the back:

-
thanks and will do mayb a new relay if i can find the umber for it?
-
if i find out what it is i'll post here
-
top man this is really doin my head in now! :laugh:
-
no problem, trust me i know how you're feeling... thats why i stripped out everything and started again!
-
please lord dont make me have to do that!!!!! :evil:
-
No... i'll doubt you'll have to go that far, if you look at my project page, link below. you'll see why i had to do it....
-
omg thats crazy i wouldnt no where to start my head is starting to hurt just looking at it! :laugh:sweet looking car
-
18 is the x-over relay, which turns off non-essential eectrical items when car cranking over. the coolant relay above the fusebox is #42 or 43, but all it does is control the coolant level warning light, if you just pull the relay it'll disable that function but the temp gauge will work as normal.
-
could sumbody post up a pic of there earth wire on the rocker please?
-
update ive took the earth of the rocker cover and cleand up both ends with sandpaper also the brown wires goin on to the battery and guess what ive been drivein it for 20mins and the temp has ranged from just under half to just over also i parkd up to let it get hot to test the fan and it now cums on at 3/4 and brings the temp down to not much over half as soon as i drive back to the middle again and if i can speed up just under the half way mark!what do ya think fixd?
-
sounds good to me... id finish what you started if you can, like i said before, make sure all earthing points are clean and in good condition. also get those relays sorted out so they are not hanging by their wires.
-
relays sortd ish couldnt get them all clipd in but thay never was will thay be ok?how many earths will be on the car 88 jh code?
-
ive been drivein the car today fine temp smack in the middle :cool:so i left the car to run buy its self and after about5/10 mins the temp got to 3/4 fan kickd in for about 12secs then about 20/30 secs later again did this for about ten mins and the temp never went up but also never went down stuck at 3/4 the hole time is all that right?also when i drive it again it soon goes back down
-
sounds about right mate, my own is nigh on constantly in hot weather and even when its chilly the fan is comes on every 3 or 4 mins if sat stationary,
as yours, once on the move it sits at halfway or just under, as long as your not overheating or losing coolant you should be fine
i have tried different clocks and relays in mine and they all read different when hot
with yours its just a case of getting to trust that the system is doing its job. keep a can of coolant and a few spares and tools in the car :wink:
-
lol thats exactly what it is its hard to trust it after six months of tryin to fix it with no joy and its lied to me b4!but its never run so cool and sweet as it does nw :cool:i thort the fan would bring it back to half tho?not to botherd as its runing sweet and i can enjoy it just in time for hour 2weeks of summer that we will have!
-
really glad things seem ok.... sounds fine to me. hope you didnt waste too much money on trial and error although thats sometimes the way! i hope i can get mine on the road for the 2 weeks of summer. got a way to go, hope the missus lets me get on with it now! :smiley:
-
lol spend a lil water pump 2xfan swich 4xtemp senders gsf ones 1x vw one 1x fusebox 1x rad 1x expansion tank and cap 3x thermostats and a feck loads of hours!but so happy working now still cant beleve it!the last problem now with i have only just noticed that my mileage and trip maileage isnt working any ideas on that one?what you got left to do to urs now the?
-
i feel your pain.... been there before!! dude youve seen my project page, if u look at the interior shots, thats where im at... its do gutting because it was a minter a few years back!..... i'm hoping from this weekend onwards i can get some real time on it.... cash is the ony prob though, as i will need to buy some seats and wheels which is my 2 major required purchaes... unless she gives me some horrible surprises with other issues.
-
at least it will be mint when ya done and you can be pround of all the work ya done good luck dude what wheels and seats ya looking for i will keep my eyes out 4 ya
-
cheers mate... my white one had 14@ BBS RA's the spokey ones from an early mk2... i think id go for them on this as the car has a proper old skool look about it as fars as the bbs body kit and spoiler goes... either that o some 14s with dishes, anythin considered but its gotta be cheap... missus is making me spend or our wage on the house!!!! as far as seats go, anything dark in coulour that will fit for now.
