Coolant from oil cooler

Postby Tracee » Sun Oct 06, 2019 9:12 am

My MK2 golf GTi 8v pb appears to be leaking externally from the oil cooler. Feels like it's coming from the corner of the cooler. Is this possible?
I've just about had enough of this car!!! Anyone wanna by a 54k 3 door!

Leaking coolant externally not oil.

Can’t help with the fix but a well sorted mk2 can be better than a five year old box of electronics on wheels

The oil cooler is a water based system, it's probably just failed, pretty common, especially due to the age of the car.
They're actually pretty cheap...

Cheap and a fairly easy fix. Like most things on these cars doesn't cost a lot to do and can be done with some basic tools (unlike the 5 year old box of electrics mentioned above). I guess the problem is when all these simple, cheap fixes add up it give the appearance of never ending issues and continual cost. But look at it this way, if it's failing after 30 years and the fix is £30, suck it up get it done and cross it off the list of things you won't need to do again. Eventually you'll have replaced everything :D

Yep you're right so far
Service kit plugs, oil and filter air filter, full set of wiper blades.
Both fuel pumps and all fuel lines.
ALL brake lines both Flexi and solid. Brake disc, pads, bearing, caliper carriers and bolts all round.
New sump pan and gasket, cleaned out pick up whilst I was there.
New top mounts
All new drive belts
New tyres all round
New coolant pipes
And now oil cooler
I've done it all myself plus working full time.
Just getting frustrated, booked the MOT but had to cancel it cos it sprung a leak!!
I went and got the parts yesterday. Do I need to drop the oil from the sump? Or can I just remover the oil filter?
Thanks for the words of encouragement
On the upside I haven't found I speck of rot

You'll only have to drop the oil from the filter and the cooler.
But you'll loose a fair amount of coolant too, so be ready for that.

I'd take the pipes off the cooler first, then let the coolant drain out.
Once that's stopped get an oil catcher under and take off the filter.
Once that's off, it'll expose a nut on the threaded pipe (that you screw the filter on to).
Take that off and the cooler will drop off.
I'd also get a new o ring for it when you refit the new one :thumbs:

Yep all done, took about an hour start to finish. I f*ing hate those hose clips (just needed to vent that)
It's started to pour down so just having a cuppa whilst that passes then back out and see if we have cured the issue

Yeah I have a set, they do make it easier, but I still dislike them!
Anyway, all done just going out to double check everything on the car is torqued up today.
And, finally it's MOT time (first in one in 8 years for this car)
Thanks for help,
Appreciated as always.
