hi,
have a few q's about the running temperature on these cars.
once my car is upto temperature, sometimes while driving the guage can sit slightly below 90 (almost like the wind is cooling the car) like at 89, 88. is this normal? when im still it will always be at 90.
just want to make sure my car is safe to rev freely
cheers
-
you're fine, nothing to worry about.
-
thanks.
just out of interest how long does it take for your car to heat up?
-
depends, if it is at 8am in the winter then around 2 or 3 miles, if it is at noon in a summers day then about a mile or so, that's the water temp, oil takes about 3 or 4 miles to get to running temp.
-
This is not right you need a new thermostat
-
Dont listen to KhareBear he's a mk3 owner so a little slow :laugh: :wink:
As Tim said new thermostat. the needle should set spot on 90 once up to temperature
-
See my guide in the maitenance section

I'm sorry but what if previous owner has fitted a lower temp thermostat?...Thought about that?
90C +/- 2C is normal. if it varied between 80C and 100C then yes, tehre would be something to worry about!
-
i had same prob.. cheap part and easy to fit so nothing to worry about there :smiley:

With the correct parts it should sit and stay bang on 90c
-
kind of what i didnt want to hear :(
and it takes longer than a mile to heat up, more like 3 on a ok day.
if i was to leave it for a little bit as im running low on funds, can it cause any harm?
-
it costs £13 mate
-
lol, thought it would be more then that :grin:
how long to fit? and can it cause harm the way it is, just out of interest, like when it drops slightly is it ok to rev the car over 3k?
-
5 min tops :grin:

lol yeah you mean the temp sender :laugh:
-
oooops :laugh:.. just ignore me mac lol
-
so does anybody know how safe it is to drive the car around when it sits at 85-89. can i fully use it?
what harm is the thermastat doing to my engine when it is overcooling?
-
anything which the car aint meant to do is bad for your engine.. not sure how bad it is driving around with a bad thermostat... but i would assume it would eventually damage your headgasket?? sum1 with more experience can shed more light for you on this mate

As is its running cooler it wont harm you engine. You may see poor MPG as the ecu needs everything to be correct otherwise it will make incorrect adjustments - leaving on the autochoke longer ect ect :smiley:

Indeed.
Mine has been playing up too! I'm changing out the thermostat and replacing coolant this weekend. Poor MPG is about the only thing I've noticed in the last few days. Not sure what lengthy use would do, guess engine aint warming up properly so maybe increased wear over a longer period?
-
yeah :sad:. havnt really noiced bad mpg though.
oh well gonna have to get reading the guide
-
just done a little test, took 10 mins to heat up to 90 idleling.
then went onto a daul carrigeway and it defo dropped down :(
-
New stat then. Took me over 2 hours as it was snowing!
-
if anyones interested. i got a garage to do it in the end, the guide looked abit to technical for my machanical knowledge, cost my just just over 100 notes (2hours labour they say), think iv been rip off! :rolleyes: nice present for pay day. oh well its works properly now, up to tempeture quickly!
-
what part did they change mate? Genuine VW part?
-
thermostat, gen vw as well
-
edit didn't read properly, about £40 an hour for labour, still doesn't take 2 hours...
-
tell me about it! wish i didnt go through with it, i left it there on the basis it was gonna cost £50, then he rang me to say it was a 2hour job so the labour charge was gonna be £80, and foolishy said go through with it :cry:
-
how much do you recon i should of paid for the job?
-
I'm doing the thermostat tomorrow. Not sure on condition of coolant so also renewing that with proper VW G12++ stuff (correct mix with DI water).
All in its about £35 with new coolant and a split knuckle or two :wink:
-
Or four...
-
yeah, sounds good mate. i just didnt feel confident enough to attempt it. if it ever goes again i will try it my self, cant be spending that agin lol
-
ah mate you should've rung me, i totally missed this thread.. could've done that for you tomorrow!
-
fook me you got ripped off :angry:

shafted!! as topher said could have took it to him would have been 200 :grin: :grin: i would say no where near 100 if toph did it :laugh: failing that i would have got the oem stat some g12 and done it myself cost=parts only :wink:
-
mine has started this now too. wheres the best place to get the thermostat & coolent from? should i get it from vw? cheers tim
-
ah mate you should've rung me, i totally missed this thread.. could've done that for you tomorrow!
gutted :(
oh well onwards and upwards, live and learn and all that
-
All done today.
Old thermostat was utterly knackered!
Coolant was a dodgy yellow (p1ssy) colour too, so well due the change to G12++ nice nice.
Tim, you're a star! Thanks!!! :smiley: :smiley: :smiley: :smiley: :smiley:
