My 2000 Jaguar S Type has the check engine light on, it flashes when I drive on the highway, and when I shut the car off it takes a long time to cool down. Also I put antifreeze in the car yesterday and today I opened up the hood and the antifreeze was gone. I went to have the code read and it said I have a misfire on cylinder 6 that is the issue. How do I fix this and not spend a lot of $?

I have 2000 Jaguar S-Type myself. It sounds like you may have multiple problems. The misfire on Cylinder 6 could be a your ignition coil is going bad. There is a coil located on each spark plug. These usually have to be replaced after 75K miles. My suggestion is if you have to replace one, then replace all of them. On the six cylinder engines, three of the coils are located under the intake manifold (expensive to repair, dealers price is $600). The intake manifold needs to be removed to access the coils. The other three can be accessed by removing the plastic cover. Regarding the cool down time. Does your electric radiator fan stay on after you shut off your engine? It should remain on for a couple of minutes after turning off the engine and it should be on when the engine is warmed-up. If your car is over heating, the red temperature light on the dash will turn-on and your temperature gage will read high. Regarding the missing antifreeze. The antifreeze could be leaking out of your reservior cap. Check to see if you have any pressure or feel air/water coming out of the cap. If so, the cap will need to be replaced. Becareful, the water will be extremely hot. If you cannot detect any visual leaks or steam coming from any of the hoses, then the antifreeze maybe leaking internally. Check to see if you have any white smoke coming from the exhaust pipe. Without correctly knowing what the root cause is of the problems you are having, it would be difficult to advise you on what to fix without further trouble-shooting. To avoid spending alot of money on repairs, my recommendation is to find a general mechanic with some knowledge on Jaguars. Jaguars usually require certified trained mechanics to work on these types of cars. The repair manuals are often very diffilcult to obtain without spending hundreds of dollars.
