The thermostat is the part the radiator hose goes to the engine. It should be a bolt on piece with two bolts. Remember to put the thermostat in the right way otherwise it will not open.

How do u bleed the water system for overheating?


The most common issues with the cooling system can be broken down into 3 categories. (Fluid Type) (Fluid Purity) (Stuck Thermostat)
(Fluid Type)
If your vehicle is cooled with *Dexcool* then your system will need to be flushed regularly. About every 7k-10k miles or so. The reason being, Dexcool congeals (gels) as it gets older, and will clog the entire system from radiator, to the heater core, stopping the flow of coolant.
(Fluid Purity)
If you are replacing your coolant with tap water, it will not have the cooling capacity of a proper 50/50 mix.
(Stuck thermostat)
Coolant will not circulate if your thermostat is frozen shut. There are ways to test it, but in most cases, it is easier, and sometimes cheaper, to just replace it.
Now, to answer your original question, take the top radiator hose off at the radiator, then loosen the butterfly bolt located at the bottom of the radiator. Not all radiators are equipped with the bleeder, so simply take off both the top, and the bottom hoses. This will drain all coolant from the radiator. To do a "fluid flush" is a bit more difficult. Remove all hoses going to the radiator, remove the thermostat, and at the thermostat connection to the engine, purge the system using a garden hose tapped from your home. A shop will do the purge with 50/50 mix to flush the system and catch the old fluid as it comes out, but not needed if you do it at home. Flush the radiator the some way, using the top at the hose connection point. Just run the water through until it comes out clean. Reattach all hoses and thermostat. Go to your local parts store and buy a 50/50 premix that is appropriate for your region.(cooler for warm weather, warmer for cold) and do not add water. They come mixed ready to put in the vehicle. Make sure you fill it up where you are supposed to. If you have the old style radiator, the cap is located directly on the radiator. If you have a reservoir, fill it up to the line. *****Make sure you you start the vehicle to operating temperature to fill the reservoir to the appropriate level.***** I hope this helps. Good luck!

How to change my engine coolant in a 1992 ford ranger-v6 3.0 engine, with what kind of coolant and how much of it


Hello again Vicki, you can read my first post to you on type. Now for where and how. Put suitable container under radiator drain valve. Start to drain old antifreeze, you can also loosen radiator cap for faster drain, but make sure antifreeze doesn't start to spill all over your driveway or garage floor. When radiator and engine are mostly drained, I would recommend to change the thermostat. Follow the top radiator hose down to the engine. This is where you'll find the thermostat. Remove the attaching bolts and remove thermostat.If you wish to flush your engine,you can put water down the thermostat hole as well as the radiator cap hole, or you can do a fancy flush. Shut drain below, reinstall thermostat housing without thermostat, fill radiator with fancy flush cleaning solution and water replace radiator cap ,run for time stated on can of flush. Now you go back to where I began and start the draining again. Dispose off antifreeze correctly it is dangerous to animals if they ingest. Close drain,and fill engine with antifreeze thru thermostat housing, when almost to top install new thermostat and gasket. fill radiator almost to top, start engine, open inside heater and let engine warm to operating temperature. At this time the antifreeze level will drop, because thermostat will open, and you can fill some more .This should eliminate any possible air bubbles. Fill your coolant tank. I would like to know how you make out. GOOD LUCK.

Luke warm heat in a 2002 expediton


Start with Flushing out your cooling system. Flush it out with Preston Radiator flush, you have your preference of ether the super flush which takes 3-6 hours or the 10 min flush which is good if you don't have the time to flush out your cooling system.

After you have flushed out your cooling system, replace your thermostat and you should be good for another cold winter driving. What happens is that after a few years of the coolant not being serviced, the coolant crystallizes and clogs up the heater core and radiator causing poor circulation. Poor circulation will cause poor heat and or overheating issues to the engine.

Before you go through all that inspect to make sure you have the right amount of coolant in your cooling system.

Good luck and thank you for using fixya

My car is running hot do u think i need to change the motor?


buy a radiator flush kit, some prestone flush additive, and even maybe a new thermostat, and a simple haynes manual for your auto. The manual will tell you where and how to change the thermostat, and how to drain the radiator, and how much radiator fluid you will need. The flush kit will instruct you where to put the flush fitting.
Remove the thermo, flush the motor, install new thermo and gasket. Add radiator fluid, done. This should solve your over heating probs. Don't let it over heat! You can cause major probs then.

You could always take it to a shop and pay the $200 to do it for you. My way would cost you less than $50.

please click yes if this helps. thanks

How i can replace the thermostat of 2001 eclipse


The thermostat is located on the engine block, follow the upper radiator hose from the radiator to the engine thermostat is there. When you replace thermostat either it has a gasket or maybe o-ring or both, make sure you replace them also. Scrape the old gasket off completely or when you install the new one it will leak. Also have antifreeze so what coolant you loose you can replace or flush radiator with a radiator flush made by prestone or other manufacturer, and follow instructions on it.If hoses look bad, have cracks good time to replace also. take them with you when you go to autoparts so you can get the right one.
