Does anyone know roughly how much the parts are to do an oil cooler?

Pat

[razzo]

Approx £130-£140 all in

Thanks,

just need to find the money now

TC card at stealers saves a few ££££  

[psl]

yes, I've got one, and intend to use it to get the best price.

[serek]

on TC around 90quid for lot

Is it obvious one striped down whether it is the oil cooler that has failed?

if you have oil in your water oil cooler if theres water in your oil head gasket  

[bunnyfoker]

not quite as clear cut as that, if the whole in your oil cooler gets big enough, (if you like me wait to long to get the job done) the when the engine gets hot and you turn the engine off, you can get reverse flow of water back into the oil,

all sorted now, after getting a secondhand oil cooler that had been fitted for a couple of weeks to a car that had been written off! from fleabay for £20 and a good dollop of tiger seal, jobs a goodun, at least this ones stainless steel

The old one will have been stainless to.

Tiger seal is not recommended either!

You get some water back into the oil even with a small hole!

Hi there, you seem to be well informed on Omegas...
Why on earth did Vauxhall put an oil cooler inside the engine, in water that is hot, rather than outside where it can be cooled by cool air...??

Gets the oil and water and thus engine upto working temp quicker thus reducing wear and emmissions probs.

Keeps the oil at a more consistant temperature throughout engine working range as the water thermostat/radiator is effectively safeguarding both.

..... or something like that....

Yes, you want the oil to be running pretty hot anyway - around the 100 degrees C mark. Oil temperature is only a problem if it gets above 130 degrees C or so. Thus, with an oil to water cooler the oil can't be over cooled because it would only get as cool as the water (circa 90 degrees C). There is also an added advantage that it drags the oil temperature up quicker following a cold start.

With an oil to air cooler you would also need a thermostat to ensure overcooling doesn't occur and the oil lines and connections, and the cooler itself would be more prone to damage, damage that would probably result in the engine getting lunched due to lack of lubrication.

Oil to water coolers are quite common, but usually in the form of a sandwich block that sits between the oil filter and engine.

An oil to water heat exchanger is THE optimum solution.

It will heat the coolant faster during warm up (the oil heats faster than the water normaly) and then the oil will be maintained at a nice constant 90-100 degC tanks to the collant setup.

Its compact and its VERY reliable if the engine is serviced correctly.

Hi hotel21, Kevin Wood, and Marks DTM Calib....
OK thanks, that explains it very well...
