Why am I getting warning messages in my 2006 Jaguar XK8

ANSWER : Hello. If you had gotten this warning message along with an overheating condition then I would be a little mindful about a possible cooling system issue. These can come and go sporadically if the issue is something like a thermostat. If the coolant is full and nothing was found then it may be fine to drive for now but I would keep a close eye on the temperature gauge when this occurs. If the engine is not actually getting hot then the issue may be with the electrical system and not the cooling system. If you are going to have this repaired, consider YourMechanic, as a certified mechanic can come to you to [diagnose why you are getting these warning lights] https://www.yourmechanic.com/services/warning-light-is-on-inspection

ANSWER : Hi there. For the coolant light to go out, you would need to have the coolant between the low line and the full line for the light to go out. If the coolant is low and keeps on being low, then look for any signs of coolant leaks. You may have to use a coolant pressure tester to pressurize the reservoir to allow the leak to be found.

If you need further assistance with the coolant being low and the warning light being on, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Hello. A battery saver mode light can sometimes be set off by an issue with the battery, but it is also often set off if a problem occurs with the alternator, such as low or excessive output from a failed voltage regulator.

I would check the alternator to make sure that it is in proper functioning order, as an alternator issue can not only cause problems with the vehicle, it could also cause damage to the battery.

If you’d like to get this repaired, feel free to contact a certified mechanic who can diagnose the cause of the battery light firsthand and replace the alternator if necessary.

ANSWER : Hi there. Unfortunately, there is no black & white step for removing a broken gas cap. If the gas cap is stripped or spinning around, it has to be carefully drilled out. This should be completed by a professional mechanic to avoid mistakes and debris falling into the fuel cell. If you live in one of our service areas, one of our professional mobile mechanics can come to your location and complete the gas cap replacement.

ANSWER : Check the oil level to be sure it is correct. If the level is correct, the oil pressure should be tested using an external gauge. The purpose of that test is to see if the pressure is actually low, or if perhaps the warning light is malfunctioning. If the pressure is low, the cause will have to be sought and there are a few causes including a failing oil pump, blocked pump pick up screen and so forth. To resolve this, the recommended service is an oil pressure diagnostic. If you request that service, the responding certified mechanic will travel right to your location and get this diagnosed and resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.

ANSWER : You may have a clogged heater core that may be prohibiting the outer linings of the heater core to get hot. As you know, the heater core is a series of tubes that the coolant runs through that generates the heat from the warm coolant after circulating through the motor. These tubes can occasionally develop a buildup on the inner walls such that when the heater core is "flushed" this buildup on the inner walls of the lines remains and still allows the coolant to flow through the heater core. It is important to note that when the heater core is "flushed" it is possible to get good flow through the heater core while the inside walls of the heater core remain caked with buildup. As a result, the buildup on the inner walls prevents the temperature from rising to its capability due to the insulating effect of this buildup on the inner walls which will prevent the necessary heat transfer to properly heat the inside of the car. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your heater core.

ANSWER : Hi there. Unfortunately this is common for this vehicle. Most of the time it will need brakes before it even hits the 20,000 mile mark. As for getting the brakes done, to dissipate heat right and to provide proper braking the brakes and rotors must be replaced together. If you want to have your brakes done, consider YourMechanic, as a certified mechanic can come to you to replace your brake pads.

ANSWER : The XJ6 uses a 120 amp alternator (AC Delco 334-1203) while the XJS uses a 115 amp alternator (AC Delco 334-1859). The terminal connections on the two alternators are NOT in the same position. Inasmuch as the part numbers for the two applications are different, the parts are considered to be not interchangeable. As a practical matter, if the pulley is IDENTICAL in EVERY respect and the pulley is in the IDENTICAL position in the serpentine drive belt circuit (same plane!, same position), and the alternator fits the frame, you can probably use it without ill effect. However, if the alternator is returnable, the optimal solution and the recommended practice is to return it and buy the actual part required in the catalog. If you desire alternator relacement by a certified Mechanic, dispatched by YourMechanic right to your location, please request alternator service and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
