A faulty or non-functioning thermostat housing in your Jaguar is one of those things that if neglected, can cause a lot of expensive issues. This is why it is important to diagnose any thermostat problems at their early stages, before having to pay the heaviest price of a damaged engine. Let’s look at some insights from experienced Jaguar mechanics on how to properly diagnose your thermostat housing and how you can have this repair done early to avoid having your engine be a total wreck.

How To Determine That Your Jaguar Thermostat Housing Is Failing

  • Check Coolant Levels: The first sign that a thermostat housing might be failing is when you notice there is either high or low coolant. If the coolant level is low, there may be a leak somewhere in the cooling system, which could be a crack from the thermostat housing or other parts. You must always check the coolant reservoir to see the level of the coolant in your Jaguar.
  • Inspect for Coolant Leaks: The best way to be sure that your Jaguar has no leakages of coolant is to park your vehicle in a clean and dry place and leave it for several hours. After some time, you should check under the car for any droppings of coolant. If you’ve located a leak, you should trace it up, and maybe it will come out from the thermostat housing or other parts.
  • Look at the Thermostat Housing: If you have a feeling that the thermostat housing has failed, then it is recommended that you take a look at the housing part. It should not be cracked, damaged, or have traces of coolant leakage around the housing. If you see any of those, then you should fix it immediately. Many Jaguar models have thermostat housing near the engine, so you can easily examine it after removing the engine cover.
  • Monitor Engine Temperature: Check the temperature of your engine when you are using the vehicle. There are times when the temperature rises or the engine begins to overheat. This may be due to a faulty thermostat, as a result of defective housing. If the issue keeps coming up, you should let a professional mechanic run a diagnostic check on the cooling system.
  • Test the Thermostat: If the housing appears fine, then the thermostat can very well be the problem. The issue with a stuck thermostat is that it can either lead to overheating or the engine does not get to the proper running temperature. This can be resolved only after testing the function of the thermostat and knowing for sure if it needs a replacement or a small adjustment.

Replacing or Fixing A Thermostat Housing

  • Replace the Housing: If the housing is cracked or severely corroded, it will be necessary to replace it. This is a basic repair, but the work needs to be done using quality parts to avoid having to repeat the process after a short while.
  • Replace Gasket: The thermostat housing might still work but may be wet. If that is the case, then the gasket has to be replaced. If a gasket is old or damaged, it can lead to leakage, so replacing it will solve the leak.
  • Flush Cooling System: When the thermostat housing or gasket is worn out and replaced, it is advisable to clean the cooling system so that any foreign material that may have gotten in during the failure, is washed away.
  • Regular Maintenance: To avoid such problems in the future, ensure you take your Jaguar cooling system for regular check-ups. Always replace the thermostat and housing at the right interval or during general checkups, if your Jaguar is an old model.
