3.9 overheating

Pacman · 2005-06-19T12:24:30+00:00

I've just become the owner of a tidy RR Vogue SE 3.9; purchased it yesterday, all the electrics work, brand new tailgate, clean interior and exterior etc etc. It's done 114,000 mles, and upto 81,000 (3 years ago) it was serviced religously by the same LR dealer, and all the receipts and stamps are present. It was MOT'd last month, with no issues, so I thought it was a bargain.However there is a slight problem with the engine. I drove it back home 30 miles away, and it was a dream to drive. However the temp gauge was running on the high side, bordering on the white and the red, with some very slight swings towards the white a bit more. When I got home, I let it cool and checked the coolant levels. It was a little low, so I topped it up, and went out again. However it was getting hot again, so I got back home to investigate. The rad pipes were red hot to touch, and I could hear a hissing sound from the expansion tank. After a few minutes of engine off I slowly opened the expansion tank, to be greeted by a waterfall of boiling hot water pouring out the tank. After about 20 mins I filled the tank back up, and without the cap on, started the engine. My mate was round (an aircraft mechanic) and he watched the tank as the engine was running for signs of bubbles (Head gasket?), but there were none. Everything was OK for about 5 minutes, when suddenly a mass of air/gas worked its way through the pipes and then more hot water came gushing out the tank.I changed the thermostat this morning, flushed the radiator (in case of blockage), I couldnt flush the heads because I couldnt get the drain nuts off, problem still there. Any ideas anyone?? As mentioned, don't think its head gasket as there are no bubbles in the expansion tank, and nothing coming out the sides of the heads, however I'd welcome your opinions.I think I've been stung, although in hindsight I paid below the book price for it so Caveat Emptor.....I actually phoned the seller (a trader) back; he...

It must have some means of starting and an energy source for that method. Hence putting "start motor" in quotes...

That would be my guess as well.

The starter motor on our GT is a V12 Detroit Diesel - 16l I think.
