As I still have the front end off of the car while finishing my engine conversion I was thinking it would be prudent to fit an external oil cooler along with pressure and temperature senders.

What have people fitted with regard to make, size and location? Also have people used thermostat take offs and/or ditched the normal oil cooler?

I was thinking of trying to fit one in the drivers side gap behind the bumper as I have vented side grills.

The reason why I'm thinking about this is that I will be using the car for track days more now and hopefully getting it turbo'd/charged at some point.

Not sure it's entirely necessary tbh. My mate's old MK5 R32 rarely went over 94 degrees on his MFA with the stock oil cooler.

If you defo want to use one, keep the stock cooler and get a sandwich plate with eighty deg stat, otherwise the oil will take forever to warm up.

Oil ideally needs to be around 100 degs so that condensation from warm-up can evaporate. I had a 13 row mocal on my old car and over winter, the oil never got over eighty degrees!

Best thing you can do for track work is fit the MK5 sump and pump. The MK4 sump only has a couple of fins to keep the oil vaguely around the oil pickup head but it's nowhere near as good as the MK5 sump, which has a proper windage tray / baffles.

Stupid forum. The smilies should read 'eighty'.

 

[VR6Rich]

Yeah sadly I saw about the MK5 sump/pump swap after I bought a brand new MK4 pump :-( So wont be doing that quite yet.

Fixed

 

[CorradoR32]

Lol, cheers, I suppose I could have done that myself

Yeah I've been considering doing the MK5 pump/sump as well but the prices have gone up a lot since I last did them

If it helps, USA mk4 R32s had additional oil cooler in the driver's side bumper vent area. OEM parts therefore are available to retro fit

What parts are needed?

 

[birdiemachine]

Oil temp in my mk5 never goes about 100 and that was during some really long heavy motorway drives at 140 plus for 30 miles etc

Greame has done it using touarag parts. Not sure why this way, and not the USA way, but it's still OEM and all part nos are there for u

 

[VR6Rich]

That's not an additional oil cooler though, just a bigger version of what we have already.

 

[Gti Fly]

Sorry can't seem to find a detailed thread on VWvortex for you now with what you need.

The USA R32s do have an additional engine oil cooler over UK cars, which is why their cars came with the vented mesh for the drivers side bumper grill, and ours weren't vented

 

[VR6Rich]

Ah right that would make sense then.

 

[Dent Reform]

why not try the toureg oil cooler as it is much larger and fits in place of the OEM unit

I've got a Mocul 25 row setup in my drivers front scoop with sandwich plate and stat.
Works ok for me and rarely gets over 100c on load.

VW alter the spec according to climate. Smaller water/oil heat exchanger for cold climates, the normal one for temperate climates like ours and hot climates like florida and california, it seems they get an external one!

Its for watercooling and TT 3.2 have it on your passenger side. I have this toureg cooler and on normal highway driving (140km/h) i hit to 116C on race track 2 laps and 134C

Cheers Steve.

Did you keep your standard heat exchanger as well? Any chance you know the specs of the cooler such as the width? Also what length hoses did you use?

 

[VR6Rich]

That looks like a cooler for the power steering as well in the last photo?!?

Don't think the TT has a standard heat-exchanger for oil, or mine has been removed for that long I've forgotten.
Here is the 25 row I've got with 3/4 bps fittings.
The hoses were custom made at the shop and are about 3ft long..

You can just see where the cooler if fitted and hoses..
