Hi everyone, I think I already know the answer to this one but here goes anyway 'did the S3c come with an oil cooler?'

The reason I ask is that mine seems to have one and from what I can tell always had one. If it is an oil cooler (which is what it looks like to me, but then I'm a begginer when compared to most of you experts out there) it's located on the top of the forward horizontal chassis rail ahead of the steering rack and behind the radiator.

Just wondered if anybody else had one and if there was a chance it might be standard?

I'll try and attach a picture tommorrow and perhaps someone would be good enough to confirm from that.

Thanks, Stu

Stu, I have a 1992 S3C with no oil cooler. So guess not a standard fixture.

No they did not have oil coolers, not to my knowledge anyway...though I don't think it's difficult to plumb one in. But I find my S3 to cool pretty well, just got to make sure everything on the cooling system is in good working order. I can see the reasoning behind the thought of having one fitted however, but I don't think they were a standard fixture.

If the pipes go to a "sandwich plate" between engine block and oil filter I'd imagine it makes things quite tight down there ?
Have you done an oil filter change yet ? scratchchin

No sandwich plate as far as I can see, I've changed the filter a couple of times and whilst its tight its no different to the usual grazed nuckle fiddle.

Here a couple of pictures



This is what one of the pipes terminates in to (looks like a damper of some sort?). I thought this was fuel system related. The other disappears down behind the back of the engine, just visible in this picture at the bottom with two hose clips on.



Any help to enlighten an amateur would be much appreciated.

Looks exactly like the oil cooler I fitted to my Mi16. I am not sure what that unit is that you referred to as a "Damper" though.
I considered fitting an oil cooler myself along with a remote take off for the filter. The filter is a nightmare to change so I thought relocating it would be a good idea.

the "damper" with the yellow dot on in your pic, is the fuel pressure regulator. If the cooler is really plumbed into that, as you say, then it's a fuel cooler, not oil. Certainly not standard!

I thought that was a fuel related regulator but why on earth would you have a fuel cooler? What are the benifits of cool fuel? Better atomisation? Hardly seems worth the bother. The pipes (with WURTH written on them) are lagged with a silver sort of heat resistant material between the cooler and the regulator.

Thanks for everyones input but this is getting more and more puzzleing!

Cooler fuel = more dense = more power, same theory as with cooler air to induction although I wouldn't have thought it would make much difference to an aging cologne.

Bit off thread but generally in line, remember the Formula 1 scandal the year Lewis Hamilton lost out in the final race when they should have disqualified a the two BMW drivers and one from another team for using fuel that was too cool as it gave them more power. The cynic in me says the disquals would have changed the world championship so they decided fines were sufficient.

Anyway cooler fuel = more power

I don't think its a fuel cooler. Although I see the point of cooler fuel I don't think it would be wise to have a cooling unit full of fuel at the front of a normal road car - the problems could be catastrophic.
My money is on an oil cooling unit.

Well if it's connected into the fuel system, as the op says, its effectiveness at cooling oil is likely to be somewhat impaired...

cooler fuel = more power but also less chance of vapour lock in a hot engine bay. Cerberas have them as standard! Not like that, but a cooling pipe across the front of the chassis.

Chim / Griff's with aircon have a fuel cooler that is a jacket around the cold aircon pipe - it cools fuel returning to the tank. I guess there may be similar arrangements on other later cars as Andrew has described above.

So I should keep my replies to strictly facts then as opposed to any opinions? tumbleweed

No, you're entitled to any opinion you like.

I know what you mean, but the car runs so well as it is/was before I started to take it apart I think maybe I should just leave it alone incase I b****r it up smile especially after all the time and effort I'm putting in with the refurb.

Perhaps I should pull off a pipe and see what comes out?

if you've followed the hose correctly and it's connected to the fuel pressure regulator as you show, it can't be anything other than fuel...

But at least then you would know.

1. reckon our friend has followed pipes correctly
2. pipes look too thin for oil ?
