Research on Thermostat for Jaguar XJ8

Since 1968, the XJ has represented the crowning glory of Jaguar's line-up. With a few exceptions, the various versions of the XJ haven't differed much from each other. Until 2010, when the Ian Callum-designed model was launched. It was only the fourth time an all-new XJ had been created, and was the most radical. Yet for all those who criticized the modernization of the line, the XJ marked the rebirth of the brand.

Callum himself would probably challenge his detractors to define what a Jaguar is supposed to look like. For the record, the XJ previous to Callum's 2010 reinvention didn't exactly conform to anybody's idea of a classic Jaguar. Its faux-retro styling was the product of an era in which Jaguar had lost confidence in its ability to keep up with the times. The latest XJ couldn't be more different. That it's more confident and forward-looking is immediately apparent. It's part of a revived Jaguar that seems more comfortable within itself, having found its place as a maker of lively and resplendent cars.

The thermostat in a Jaguar regulates the flow of coolant into the engine. This helps to keep your vehicle operating at optimal temperatures. Like almost every other part in your Jaguar, you will eventually need to replace the thermostat due to wear and tear. Because Jaguar has so many different models, the exact methods for changing the thermostat will vary from car to car. The basic steps, however, will be similar for each model.

Do I need to drain the coolant completely before replacing the thermostat or can I just replace the thermostat and top up the coolant to replace any that is lost in the process?

You can replace the thermostat without draining all the coolant. Spill what you must and then top up with the same color coolant diluted 50:50 with tap water.

What can cause a coolant thermostat malfunction code to appear on a Jaguar?

A faulty thermostat can likely cause this to happen. First, check the component for any issues and see if it solves the problem. If not, make sure the mixture of coolant and water is correct

What could cause a 1998 Jaguar XJ to overheat within a few seconds of driving?

It could likely be due to a defective thermostat that will need to be replaced. Other possible reasons could be a bad water pump, cracking pump impellers or a faulty coolant sensor. Troubleshoot these various possibilities to find out the true cause of the problem and repair as needed.

What could cause an error code 'C1145' to appear despite replacing the thermostat?

This could either be from a faulty front wheel speed sensor or a defective instrument pack. Have both these components properly checked to ensure what is causing the problem. Additionally, scan the vehicle to check for any other fault codes to fix the issue.

The thermostat is essential to maintain a correct balance of temperature in a vehicle. When it goes bad, it can lead to a lot of problems causing a great deal of annoyance to car owners.

What is the Jaguar XJ8 Thermostat replacement cost?

At PartsGeek, thermostats for the Jaguar XJ8 can be had for as little as $17.48 or as much as $145.48.
