OK I've got the tyre pressure down pat now thanks all so I thought I'd better have a gander under the bonnet.
So I had a squizz under the bonnet of the Pajero (cook's not fond of the w@nker wagon name so any suggestions??) and found an oil cooler for the engine oil.
Is this normal??
Cheers then
Scott
PS I reckon a large remote filter is going to go in the line to the cooler pretty damn quick.
I have one already on the shelf in amongst the spare parts for the VW.
