Title: OIL COOLER - REMOVAL OF
Post by: andyc on 03 February 2008, 23:41:34

Ok, question time. One of the other projects i've got on the go is an 85 Opel Manta Coupe which is going to get the 2.5 V6 from the scrap estate i brought from work for a oner, clutch blowen up.

Anyway the question is i want to remove the oil cooler from the "V" and make it into an air cooled version as i've already fitted a cooler from a 24v Carlton Diamond, nice and long and fits the full width of the rad grill.

Now can i just take the feeds for pipes from the pipes in the block the feed the standard "V" mounted cooler or do i need to fit a sandwich plate with stat and make a "U" pipe up for the orginal feed & return.

I'm thinking of going for the sandwich plate that way i can make up a "U" pipe with a "T" section so i can fit an oil temp sensor for a dash gauge.

Thoughts & comments please

Cheers
Andy

I wonder if it's worth bothering, TBH.

If you get into air to oil coolers, the oil will not get up to a satisfactory temperature unless you'e driving it flat out all the time, so you'd need a thermostat to control the oil temperature. That adds extra complexity and extra restriction to the flow of oil.

The standard oil to water cooler can't overcool the oil, and can actually heat the oil during warmup and light loading of the engine to keep it at a beneficial temperature. They are also only unreliable if the coolant is allowed to deteriorate.

I wouldn't do it just because you happen to have an oil to air cooler. Ask yourself if it's actually what the engine needs.

Also, take-off plates can be restrictive to the flow of oil, so I'd be re-using the feeds that are already present for the factory oil cooler. If you want an oil temperature gauge, just tap a hole in the sump for it.

Not a good idea - it is a heat exchanger not a cooler, it warms the oil up so the engine will wear less

we did this with a Mk2 cav, the cooler had blown and the guy couldn't be bothered to sort it out.

The engine oil never got hot enough, unless he was ragging the hell out of it, he had to have the pipes made up and all in it was not the sucsess he wanted it to be
