Jaguar XJ8 - Popular Questions, Answers, Tips & Manuals

As with any car run the car for about 1/2 an hour,or until it is hot.Feel your top radiator hose, if it is hard and you cannot flex it. That is telling you your thermostat is stuck in the closed position and your antifreeze, is not circulating,which would explain your cold air. I hope this helped.

If Gas mixes with water, combustion is impossible. Not only is the fuel bad, the lines and spark plugs are messed up. Water will also mess up the electrical lines and the cars computer.
First, get some gasoline drying solution. That takes a day or two to work. When the water is removed from the gas tank, add fresh 100% gas. Pull all the spark plugs and clean the ends and check the gap for proper distance. Make certain the plugs are clean and dry before you reinsert them into the ports. Dry and clean all spark plug wires. Check you battery also. It should not have corrosion on the poles. If they have a coating, clean them and make perfect contact with the power cables. Try to start the engine now. Good luck.

I'd change the plugs as per this link, and swear by an 'internal service' by chemicals as manufactureed by BG Products available on Ebay (The chemicals are for professional use so stick to the instructions). If you haven't seen this thread, take a look.

I. make sure your battery is ok first.
2.using your key unlock and lock your drivers door a couple of times; then try starting the car.
3.if you have a spare key ' try using it to see if it start your car. if it start with spare key then your main key needs a new chip.
good luck and god bless.
