What is a thermostat?The thermostat is a valve that helps control engine temperature. When the engine is cold, the thermostat stays closed to block coolant flow to the radiator, letting the engine warm up faster. Once the engine hits a certain temperature, the thermostat opens up, allowing coolant into the radiator, where it can cool off and keep the car from overheating. Thermostats can be controlled either mechanically or electronically. What are the symptoms related to a bad thermostat?The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed. A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air. A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues. ยป LEARN MORE: Signs of a bad thermostat, and how to fix it Can I drive with a thermostat problem?If the thermostat is stuck closed, no, you should stop driving immediately; if you don't, the engine can quickly overheat. An overheating engine should be shut off, and the vehicle should be towed. Overheating can severely damage the engine after only a few minutes. If the thermostat is stuck open it may not cause engine failure, but you'll likely notice poor performance, an ineffective heater and bad fuel economy. It should be replaced at your earliest convenience. How often do thermostats need to be replaced?It all depends on the type of car you have and your driving conditions. The thermostat does not wear the same way a tire does, but will eventually fail and require replacement. Often, a new thermostat is recommended as preventative maintenance any time the cooling system is serviced, such as during radiator hose replacement or a timing belt service. 08-13-2010, 08:42 AMJoin Date: May 2008 Location: Bayville, NJ usa Posts: 66 Likes: 0 Received 0 Likes on 0 Posts thermostat housing replacement 2004 XJ8 - 70k miles thermostat any others?

Especially since the epoxy just cracked last night and the car is officially retired til it gets fixed. 08-17-2010, 02:14 AMJoin Date: Jul 2008 Posts: 17 Likes: 0 Received 0 Likes on 0 Posts Thermostat housing replacement Hi- Join Date: May 2008 Location: Bayville, NJ usa Posts: 66 Likes: 0 Received 0 Likes on 0 Posts Thx Jag but I think we're working on two different types of cars. As fate would have it I ran out of time for answers here and just started to tackle the job using Topix shop manuals. Firstly let me say that the Topix crossover vin is wrong. My G19### manifold needs the G44###+ procedure. The neck is not aluminum nor is it detachable from the thermo housing on my engine 2004 4.2L NA X350. The job actually is turning into a nightmare. I have stripped the top of the engine so it looks like I'm re-ringing it. The 4 bolt flange on the thermo neck attaches to the block under the manifold so it definitely has to come off. I have managed to lift the front of the manifold enough to remove the housing but to properly clean the manifold and mating surfaces I have to go to the official Jag technique. It begins with removing the windshield wiper arms, then the cowl. This to get to a couple things in the back of the manifold. I'm surprised I don't have to take out the gas tank. I am really annoyed at the person that spec'd a plastic housing then buried it $2000 deep in the engine compartment. If I meet him in a pub I will without hesitation stab him. 08-17-2010, 09:45 AMJoin Date: Jul 2008 Posts: 17 Likes: 0 Received 0 Likes on 0 Posts Thermostat housing repl. I also have a 2004 X350 4.2, and that's the engine I was referring to. The t'stat. housing DID come off without removing the manifold though it was a close fit. Very sorry your job has turned into a real headache. Join Date: May 2008 Location: Bayville, NJ usa Posts: 66 Likes: 0 Received 0 Likes on 0 Posts Wow. I don't get it. On mine the EGR takes up all the room you need to get the 4 bolt flange apart.
