Oil cooler-To bleed or not to bleed,thati s the question

Recommended Posts

Hi to all out there

I have just changed the oil cooler om my 1981 S3 N/A for the first time,in fact it is the first time I have ever changed an oil cooler. Everything has gone smoothley and I have just filled her back up with oil. My query is,before I start up the engine,does the cooler get air blocked? if so do you need to bleed it ,if so how.

Thanking everyone in advance

Chris

Personally I've never bothered.

To bleed it you'd have to push oil down one of the pipes attached to the sandwich plate. If you've not cleaned the cooler of old oil then it already has oil in it, so don't worry an oil change is never all the oil changed, just that in the sump.

I think he's changed the cooler hardware not just a normal oil change?

The cooler won't get air locked but you could end up with an air pocket hitting the engine when it's expecting oil. The oil system will eventually self purge the air but not great. Most sandwich adapters have a bleed nipple on them. connect hose and open then disconnect the oil return from the cooler. Add oil until it hits the bleed nipple. Add a bit more oil, reconnect pipe and run engine at idle. periodically check oil level and add as required. This is on an elise so may be different.

If you want take the plugs out and spin the motor on the starter to circulate the oil, and see a bit of pressure on the gauge. I do this after an oil change, it just saves the load on the bearings under combustion before the pressure comes up.
