Hello!
 

Hello Everyone! I'm new to the site, and am pleased to be a member of the forum. I've owned my 2001 XJ Sovereign since Feb 09 and have enjoyed every moment of driving it since then. I'm British and live in the North West of Britain, but I bought my car from Sheffield, but it was first from Hull.

I've just returned from a week of driving round France in my XJ and enjoyed it, however my XJ developed a problem on this trip. I noticed the Temp gauge had crept up to the top of the red, and the warning light was on. I instantly switched off the A/C and the gauge returned to normal quickly. I initally thought it was because it was quite warm outside and I was working my way up a long hill which may have caused the heat up.

However whilst driving on the motorways the gauge crept up again, and I repeated the above again. I felt sorry for my Girlfriend who had to endure the heat of HI being blown into the cabin whilst all 4 windows were opened on a French Autoroute from Rouen to Calais. Luckilly I made it back home today, and the regular checks I gave the XJ's fluids and key engine parts threw up no clues as to what the issue could be.

I suspect it could be the Thermostat, or the water pump. I hope it's not the latter. Does anyone know the location of the Thermostat on a 01 4.0 V8? And the replacement process? Thanks for your help. Stu.
