Hot Mk1 G60

Hi all
My much loved g60 has been in the garage for a while as she was overheating. I really want to get her out again this year but need to get better reliablity. Basically, when in traffic she heats up real quickly, even with fan running constantly and oil temp gets up to 120+.
I was looking at putting an external (mocal?) oil cooler on, any other suggestions on how to get her running cooler.
Currently running with cone filter, original rad, Rallye intercooler if that helps.

cheers

Could fit lower thermostate in water pump and fit lower rad temp switch on your rad, so your rad fan will come on earlier. Put some "water wetter" additive into your coolant.
defo fit an oil cooler.
Fit a schrink baffled alu sump as this increases the oil capacity by about a litre I think.
Slim line fan with temp control so you can control when the fan comes on ie rplaces your rad temp sensor is another step dude.
Could also try and fit a larger rad ie more coolant.

Oil cooler could be blocked or thermostat not opening,try a stat from a hot climate country from VW say 80 degree rather then 87 degree uk stat,check the coolant is circulating and the rad is warm allover.G60 rads are quite small but do the job ok in the corrado and golf.Maybe upgrade to a VRrad or original 1.6/1.8 GTI rad they are bigger than a G60 rad but you may have trouble with top hose clearance....i have all this to come as im converting to G60 power right now!

Where is the intercooler mounted?

Rallye IC will only go in one place in a MK1 thats infront of the radiator and behind the grill and will not affect cooling what so ever.
Could be quite tight trying to get an  external oil cooler in the front of a mk1 especially running the rallye IC you might be able to squeeze a long thin one across the bottom but getting it into the airflow could be difficult.

If the car's fitted with the same radiator as the G60 would have originally had, and the oil cooler is the same setup (I assume it uses the stock oil-water cooler) then it sounds like you have a plain old overheating issue, unrelated to the conversion.

Obviously if its related to the conversion, and you add the air-oil cooler, then its best placed to the side, instead of in front of, the radiator; or otherwise sited optimally.

I had my mocal oil cooler re-located to inside the drivers front wing and also made a cover for it so its not damaged by debris from the road wheel.
With the standard vw coolant oil to coolant cooler then the sandwhich plate for mocal oil fitted plus the oil filter all fitted, it gets a bit tight for space near the front slam panel  

This is quite common on G60 conversions if your not running an oil cooler the standard heat exchange on the oil filter housing is a complete waste of time.
My temp gauge never goes over half way though and i'm running a mk2 polo rad which is tiny,I also use a low temp fan switch and a low temp thermostat.
My oil temp would go right up to around 140 which isn't good so had to fit an oil cooler which sorts the problem out.Also make sure you use the correct oil this helps alot.

As andy as said it's quite tight to get an oil cooler in there but can be done.

Hi guys, thanks for all your responses, it's given me lots to think about. The battery has been relocated to the boot so I have room there, trouble is its a show engine bay and I will spoil the look (personal opinion) and wanted to locate it somewhere out of view if I can ops:

thanks again all, will let you know where I get with this one.

Will hopefully get to the national meet for the 1st time this year    n catch up with whats been happening in the golf scene over the last couple of years

I am in Lincoln also, I don't want to impose, but wondered if  if I could contact you direct / ask you to have a look and point me in the right direction with your knowledge on g60's being so good?

Hi, sorry to drag up an old post.

I'm struggling to fit a mocal 13 row oil cooler with my current rad I/c setup on my g60. Basically the I/c is from a sprinter and the rad is a top fill (mk1 golf). Has anyone with the same setup fitted a mocal cooler if so where?

Cheers
