Oil cooler issue

[cobaltcodd]

After converting my crossflow to a pressurised cooling system I ran it up to temperature (when the cooling fan cut in) to check for any leaks etc.  However while doing this I noticed that my oil cooler, that sits in front of the rad. remained absolutely stone cold.

So before I try not to make a big mess on the garage floor taking it all out and seeing what's happening, anybody any thoughts or suggestions, or previous experience of this?

many thanks

Assuming your wet sump...?

If you have a thermostat in your take off plate then this will only allow full flow to the cooler once the prescribed temp has been achieved usually circa 82-92 degrees C

In the mean time oil will circulate normally around the engine with a small bleed into the cooler to keep this pressurised too.

As above. Just to add that on my engine (K Series) it takes a LOT longer for the oil to get up to temperature than it does for the coolant, especially if just idling.

Ran mine up to fan cutting in in the garage the other day, the water was showing 95C the oil 55C so don't think just getting the water up there and turning off is enough to get the oil to the point it is flowing through the cooler.

Many thanks for the info on this - instead of taking it all apart I'll wait until I've had a nice drive so everything is hot - and then check.  Shows the value of belonging to the L7C
