does anyone know a company that sells oil coolers suitable for a 2.5TD?

cheers
matt

I do!

What is wrong with the cooler in your radiator though?

Have a look at LLAMA 4x4 or more specifically for the oil cooler stuff look at Llama Motorsport plumbing pages

Better still phone me on 01938.850382 and I can tell you all about them................

David

thanks for the info. ill probley call u tomorrow if i get chance and the oil cooler is for the series

The oil cooler in your rad is more than adequate Matt. Why do you feel you need a seperate one?


Les.

its for the TD in the series 3 as im using the standard rad

Ah........I'd be inclined to look out for one of the ex-military type ones that sit in front of your rad. I'd avoid the mocal type ones casue they get blocked with mud too easily unless you never go off road.

i've got a mocal one, sited it behind the intercooler, mud still gets to it

Whilst I am more than happy to sell you a cooler and suggest that it is possible to locate one in a position where it will be very efficient or better still I could sell you a cooler that is a oil / water transfer rather than an oil / air transfer which is far more effective and simply plumbs into the engine cooling system it has to be said I am wary of trying to cool a 2.5TD with a series radiator altogether.

This engibe is notorious for running hot and would suggest you try and get a TD radiator into the car at least or better still an uprated TD rad or you will be blowing oil like the Amoco Cadiz in no time !!!

I didn't think that the heat stress problem was down to oil temperature. The engine in catflap was out of a 90 with the std rad/oil cooler arrangement, and two pistons still cracked.

Pics of the two pistons in catflaps engine:-





As this engine already had an oil cooler (standard radiator for a 1989 90), I assumed that the oil cooler wasn't doing a great deal to cool combustion gases/piston crown temperature. This is why I fitted an intercooler - working on the theory that cooler intake gases would result in cooler combustion gases.
Hope so anyway - I'm sure going to fing out!

Tonks running a 200 Tdi on the standard series rad with no probs.

You cannot fit a TD rad in whilst retaining the series front end. However it fits easy enough if you fit a 90 front end. Thats what I'm running now with a modded TD rad and it works alot better.

Jon

i've done a couple of tdi conversions into series retaining the series rad and they just dont run hot, have trouble keeping them upto temp sometimes, motorway cruising normally sees just above 80 degrees

I'v got a fairly decent TD rad (with oil cooler) if anyone needs one. £30 ish.

I don't think the heat stress is anything ( obviously a little ) to do with the oil cooling that is why I said an oil cooler alone would not IMHO be sufficient - it is radiator capacity / efficiency will start to affect a TD run through a series rad.

The Tdi ( esp. 200 ) runs very cool and a series rad witha seperate oil and intercooler will be fine. BUT aTD is not a Tdi! and does not run cool even in the arctic circle!!!

If a modifaction to the front end is the inly way then that is better than an engine that only lasts 40k from rebuild.....
