any one know what size radiator I need for a 1990 16v??? I've been told by GSF that it is there part number 17333, this describes as for the 1.6 carb model (size 430 mm) on there website - is this right???
surely it must be a different from a 1.6 carb model???
cheers
-
i think they are physically the same size but the 16v ones are double cored? i dunno
-
will ahve to make sure before I order anyway, will confirm either way!
-
yes the 16v rad is physically the same size, as a 1.6 rad, but is double cored :) The 1.6 rad isn't going to be up to the job, but a few 16v owners fit a 1.8 GTI/Carb rad instead and report lower temps. You'll need the upper & lower rad hoses too as well as the fan shroud. While you're there I would also upgrade to a 2 speed fan, you need the fan, the temp sender in the bottom of the rad and the loom from the 2 pin connector on the RHS of the radiator. It just swaps over :)
-
my head is done in!!! :undecided:
I've no idea what Im doing now!!!
I'm not going to bother with the 2 speed fan, can see it making much difference!
I might be tempted by a 8v rad though:
what about these:

then I can get the hose from GSF, £10 or each???
-
Those 2 auctions contain everything you need to upgrade to a 2 speed fan, notice the loom still attached to the fan :smiley:
Hoses can indeed be bought from GSF, but since they are so common I'd have a look in a scrappy, or even ask the guy selling those bits nicely to include them ;)
-
I brought a rad from gsf last week and had to file one of the holes out slightly as the mounts were out by about 1/4 inch. It was the correct rad with the corect part number ect. It works ok though......... :smiley:
-
well here goes, going for the 8v rad and fan, I do hope they fit and I don't need to make any major mods to get it in!!!
Just need the top and bottom hoses now - anyone got them??? :grin: :grin:
-
Right I've got my 8v rad (525mm) fan, shroud, and 8v top and bottom hoses hopefully arriving this weekend ready for there install this weekend.
Next question:
Whats the best antifreeze to use, and what ratio should I mix it with water? How much antifreeze/water does the 16v take?? Oil temp currently runs between 102 and on the odd occasion 124! I'd like this reduced if poss!
Is it worth flushing the system first?
How do I ensure there is no air in the system?
Cheers
-
Genuine G12+ coolant from VW, or febi G12 coolant from http://www.vwspares.co.uk.
I usually go for a ratio of roughly 50/50, and if empty the 16v will take just over 5 litres :)
Its definitly worth flushing the system before you refil, you don't want any crud in the new rad ;)

----->>> see the rubjonny tribute!!:grin: :grin: :grin:>
what about airlocks?? any technique involved??
-
run the car with the expansion cap off and let it get up to temperature, this should work out all the air bubbles. helps to have the heater slid all the way to red as well.
-
tribute to ...joe????
-
This is the method I use:
Run the engine from cold with the cap off and rev it to 2k now and again. While you are doing this squeeze all the pipes you can get your hands on, and keep the coolant level topped up. It will eventually start to boil over, at this point turn the engine off. Once its settled down top it up to the max mark and you should be good to go!
Even then sometimes the only way to get rid of persistant airlocks is to give it a good thrash :)
No need to switch the heaters to hot on a MK2 as the coolant is always flowing round the matrix regardless. Its good practice to do it anyway, especially if you arn't sure if coolant flow is blocked by the heater controls or not. The MK1 needs the heaters setting to hot :)

Can someone point to the temp sender on thie piccies below:::

I have a feeling that I have something missing???
See post below of whats need to convert to a 2 speed fan as said by the legend that is rubjonny!
edit::
forget that- it is plan to see in the bottom of the rad!!! :embarassed:
-
Get some new glasses :grin:
-
on there way!! :grin: :grin:
-
well its done got it fitted this morning all is OK, also seems to be running a little cooler (and smoother????) will let you know how it goes!
Onlt one problem though
(http://i21.photobucket.com/albums/b253/rowlers/fan.jpg)
the arrow points to a single connecter that doesn't seem to go anywhere?? there wasn't one on my old fan???
any ideas??
the fan does work, comes in just after the half way mark.
-
Ah I think that runs from the after run sensor that some GTIs have, the sensor is usually near the zaust or inlet somewhere and can turn the fan on when the car is off. No need to worry about it :)
-
spot on cheers fella, my old fan did use to run after car turned off?
-
The fan can still run if the engine is off, as the feed to the fan is always live so if the temp sensor gets hot enough the fan will run :)
I've nicked a few of these looms and some have this extra plug and some don't My 90 spec GTI doesn't have it, but the loom I pinched from an 89 GTI did, though it wasn't plugged into anything. I believe this sensor was on the early K-Jet GTIs and also on Rallyes/G60s. OI heard that on the Rallye/G60 the switch turns on the fan if the zaust manifold gets too hot, as they can crack under high temperatures.

you know some stuff!!!

my brain soaks up useless random information like a sponge, and i spend too much time browsing forums when I should be working :grin:
