TOP 4 JAGUAR REPAIR PROBLEMS
Replace the plastic-bodies timing chain tensioner with a new aluminum tensioner. Just a background, early Jaguar V8 engines are equipped with plastic-bodied timing chain tensioner. It was not until 2001 that new aluminum tensioners were introduced. To begin the replacement job, make sure you have all the right tools, replacement tensioner, cam cover, short tensioner bolts, and seals. Remove the cover trims, spark plug coil covers, and other wirings. With a cam locking tool, remove the sprocket bolt and washer. Remember to have both cams locked off together. Take the exhaust sprocket out and remove the old tensioner. Place the new sprocket and cam bolt to set the new tensioner. Make sure that all the bolts are tightened to secure the new tensioner. To prevent future tensioner problems, warm up the engine before taking a drive. Driving with a cold engine can really cause problems. Also, for Jaguars with V8 engines, you can preserve the life of its tensioner by changing the oil and filter every 5,000 miles rather than the recommended 10,000 miles with either 5W30 mineral oil or synthetic oil.
Remove the corrosion in the control module. The best way to resolve this problem is to determine how corrosion gets to the cooling fan control module and how it can be prevented. The main cause is the water that comes into contact with the module. Water enters from the ground wire cores and travels inside the wire insulation and then reaches the module. To avoid water from entering and damaging the module, you need to disconnect the ground wire eyelet connectors on the left inner front fender panel and use heat shrink tubing to seal it.
Just a background ,This cooling system problem can be related to the car's cat back. The cat back is a pipe in the exhaust system located between the outlet of the catalytic converter and the muffler. The main culprit of this problem is corrosion building in the cooling fan harness connector. Access the harness connection just behind the front side fog lamp. Replace the corroded harness connector with a new radiator fan switch kit. For owners of 1994 XJ6s and XJ12s Jaguar models, they can get the kit with part numbers JLM12040 and JLM12041, respectively. Remember that once you install the replacement connectors, you need "Duraseal" connector on all the wirings to prevent future corrosion.
The jamming of Jaguar convertible tops, specifically for XKX8 models lay on the hydraulic fluid that moves the top. The thin fluid, at times, turns to a jelly consistency, making it hard to move through the pipes. The best solution is replacing the hydraulic fluid. You need to flush out all the old fluid and install a new synthetic hydraulic fluid. In most cases, all you need to replace is the fluid. On the other hand, if you want temporary solution to the convertible top problem, you can also manually lock the top in place. You have to refer to your Jaguar owner's manual to find out how to do it properly.
