My P38 was delivered to me yesterday afternoon and overall I am pleased with it although it is being a typical Range Rover already.
How long does an early 4.6 normally take to warm to normal operating temperature? Mine seems to warm up alarmingly fast. I have only driven her up the farm track and back so maybe a mile and half at max 15mph and she was already reading fully warmed up on the gauge.
Last night, I did this and she got up 3/4 on the temp gauge and upon switching off their was steam coming from under the bonnet. Something definitely not right! I did find something straight away, the expansion tank cap was loose and tightening down properly stopped the steam. I came back to her this morning and the system was down 6 pints of coolant, I topped it up and took her for another test run up the track and once again she was up to temperature very quickly but this time stayed at half way and no steam.
Other things I have noticed the exhaust does seem to be a bit steamy but it is not exactly warm out at the moment so steam from the exhaust is to be expected.
Engine oil while not new is in good condition and show no signs of emulsion nor is any visible on the oil cap.
There is some coppery residue on the expansion tank cap which makes me think it has had K seal or similar in it in the past. When starting with a cold engine and cap off it is not bubbling or building pressure very quickly which is a good sign.
I am thinking the issue is likely thermostat and radiator related but have niggling suspicion that I may be looking at HG issues.

You know what these farmers are like.
