Oil Heat Exchanger

[Jrod 7]

As per fitted to the Mi16.

 

Opinions, keep it or ditch it?

What's the car's main use?

what's the car used for?

 

IMO -

 

Road car, keep it.

 

track car, fit an oil cooler as well as the heat exchanger.

 

I think a combination of remote oil filter+heat echanger assembly and a thermostatically controlled air-oil cooler would work well, its what I have seen on a few Citroen C2's Saxo's and 106 rally cars.

Main use? sitting in the garage broken!

 

Road and some basic forms of motorsport, autosolos etc.

Had mine off since 2004 with no problems.

I have a remote one fitted to my car for road & track use, works fine for both applications.

 

track car, fit an oil cooler as well as the heat exchanger.

 

Fitting this & an oil cooler is overkill though imo, most I'd do is fit an alloy sump along with it but even then you risk over cooling the oil.

the theory is that it warms the oil up quicker, which in my experience it does, but then with the thermostatically controlled oil cooler it'll never over cool the oil, but I've never fitted an alloy sump in a 205 so I didn't know if that alone would be enough.

 

also the car's I've seen with the dual setup do have sump guards, so would have less air moving over the sump.

Keep it. Provided it's not hard competitive/track use, it'll do more good than harm. Ultimately, provided you've got working water and oil temperature gauges, you'll soon know if it's the other way round

A rally car with a sump guard has less through flow of air than normal & probably works the oil harder than a track car so I can see why they use an oil cooler & heat exchanger but its not a move I'd take.

I did this on my car breifly & drove to Donington for a trackday in November but due to my heater matrix springing a leak on the way never saw the track.

Driving home that night with the mixture of a heat exchanger & alloy sump but no heater, my oil temp guage didn't move even after an hour + on the motorway so I soon swapped back to a steel sump.

 

When I removed the alloy sump it had a congealed mayo mess at the back where it was in the airflow.

 

With a 75' thermostat & oil water heat exchanger even after 20 minutes around Cadwell or Croft there aren't any issues with high oil temp & if Jordan is talking hillclimbs / sprints I didn't think the car was run long enough to get that hot.
