I thought i'd make a quick thread to show how ive mounted my oil cooler since a few people have asked about them on other threads and i didnt want to spam other peoples threads with my pictures

After the french car show last year where my car was introduced to a track for the first time in my ownership i managed to overheat my oil (~140*c) and with a trip to the nurburgring only 2 weeks after fcs i decided that it would be wise to fit an oil cooler with a thermostatic plate.

Money was a little tight so i bought a second hand 16 row mocal cooler with braided oil lines and a thermostatic plate from someone on here.

The rubber seal on the thermostatic plate was unusable so i got a new one ordered and decided to strip the plate whilst i waited for the new seal to arrive. Quite a simple little thing really:


After cleaning i re-assembled it and put the new seal on once it was all dry. I think i used carb cleaner to clean the oil off most of the stuff.


Whilst i waited for the new seal to arrive i went out and bought some fine mesh to help protect the oil cooler from stones, its approx 10mm squares zinc coated stuff from a local diy shop, came in 1m x 1m sheets for about

I helped rwgti fit an identical system on his '6 and he managed without removing his inlet manifold, he even had a PTFE gasket which puts the manifold a bit closer to the rad.

I got fed up of slicing my hands / arms on the rad and manifold so decided to take it off for the sake of the cost of new gaskets, it made things a lot easier but wasnt necessary.
I think rob went up from underneath to fit his sandwich plate, though there seems to be more room down there on his than mine even though he still has a/c like mine.

Its quite easy to get the filter into position from the top on mine, just go down from the left of the pas pump then along and into position.
Rob does his filter from underneath going upwards, so it should be accessible for you one way or another.
Having said that i think your now supercharged so things might be slightly different for you.
It shouldnt be too hard to sort out once you get to the fitting stage though, just make sure you have everything you think you'll need ready before you start

Good write up and pics



Don't think that would be a very good position for it to be honest
It would only be getting hot air from rad passing threw it

excelent thread and pictures i will use this when fittign mine. whats the differnce with the sandwich plates? isnt that where the oil pressure and temp sensors go into?i cant see from the pictures .

What do you mean?
There is already one sandwich plate which is installed by peugeot which sends the oil into a heat exchanger in the radiator to help warm the oil from cold then keep the temps reasonable when the oil is hot.
When fitting an extra cooler you just put the oil coolers sandwich plate against the peugeot one then the filter after the new sandwich plate.

There are two types of sandwich plate that i'm aware of for the oil cooler, non thermostatic and thermostatic.
I would use the thermostatic one as it doesnt allow any (or very little) oil to go through the actual cooler when the oil is cold and then opens up the flow to the cooler once the oil is around 80*c.

As others have mentioned in other threads, running with the oil below optimal temperatures is as bad for the engine as running with the oil too hot, hence why a thermostatic plate is ideal.

Perhaps that was due to clearance issues????

All production cars that I know of that run air to oil coolers have them in front of the rad,or to the side in front of the wheel area which is the best place

You dont need to get at it from the top to be honest, i just took the manifold off to make things easier, and i needed the manifold off to sort out the leaking sensor on the block.
