20054.2thermastat what is the part # for thermostat & where is

No

Thermostat & "o"ring

I would just try to get in there & separate
the housing & leave as much else alone
as possible

May be easier to get from the bottom

I have a 2004 V8 so I have different issues

Before you buy the thermostat, look at scan tool data
& coolant temp & remove the stat & check the temp
stamped on it,so you get the correct one

Then recheck your data under same run time,ambient
temp,etc, to compare new stat

Make sure you mix ONLY Zerex G-05 & Distilled Water
from the super market ---- NEVER TAP WATER IN
ANY COOLANT SYSTEM

You only getting 50 % out, with the radiator plug out,so
change every 3 years

I mix 60% coolant & 40% water

50/50 is okey

Removal & Installation

• 3.5L ENGINE

Print Here is how to do it,if it does'nt fit right make sure you have the right thermostat.

3.5L Engine


CAUTION Never remove pressure cap with the system hot and under pressure because serious burns from coolant can occur.

1. Disconnect negative cable from remote jumper terminal.
2. Drain cooling system.
3. Disconnect radiator upper hose from thermostat housing.
4. Remove thermostat housing bolts.
5. Remove housing, thermostat, and gasket.

6. Clean gasket sealing surfaces.

To install:

1. Install thermostat and gasket into thermostat housing. For ease of installation, install bolts in housing for thermostat and gasket retention.
2. Install thermostat and housing to the intake manifold. Tighten the bolts to 105 inch lbs. (12 Nm).
3. Connect radiator hoses and install hose clamp.
4. Refill cooling system.
5. Connect negative cable to remote jumper terminal

Hope this helps.

you will have to remove the thermostat & place in a saucepan or the like & cover it with cold water, & gradually bring the water up to boiling point to see if the thermostat opens, if it does'nt it is faulty & needs replacing.......hope this helps......cheers.

1. do it when cold(coolant)
2. if never done this before just follow thes step's
3. on radiator at bottom it's left side at bottom (face the car)is drain plug loosen to let some of coolant out dont have to drain all of it (gallon or so)
4. follow top hose to engine at end of hose will be thermosat housing it be 2 bolt's holding it on (1/2 inch socket )
5. before taking out bolt's take clamp off of hose & pull hose off.
6. now take bolt's out
7. lift housing off
8. look at how thermostat is in
9. take out thermostat dicard
10. clean gasket off of housing & engine block
11. put sealer on block & put thermostat in (same way came out)
12. put gasket on block & put thermostat housing on ,put bolt's in ,tigthen bolt's (20 flbs)
13. put hose on & tigthen clamp
14. close drain plug & titghen
15. top off radiator with coolant
16. crank engine , tpo off w/more coolant if need it ,let it run & come to temperture ,top off radiator again ,because when the thermostat open's coolant will begin to flow ,when full put cap on radiator ............DONE
17. JUST CHECK MAKE SURE NO LEAK'S

the thermostat is located in the housing where the top radiator hose is connected to the motor,remove the radiator hose then undo the bolts that secure the housing pull the housing apart,remove the thermostat & clean off the old gasket & clean both surfaces with a scraper or sandpaper fit the new thermostat & new gasket,be careful not to over tighten the bolts replace the radiator hose, refill the radiator, run engine & check for leaks......hope this helps....cheers

Follow the upper rad hose to the thermostat housing. Drain the rad into a pan low enough as to not lose any antifreeze. Remove the housing bolts & gently tap the housing to release the thermostat. Make sure you notice the direction of the thermostat & install it the same way. Clean both surfaces & use some gasket sealer on the housing side only. Make sure your thermostat is in the grove when you tighten the housing otherwise you might crack the housing. Hold tight & fasten bolts. Refill rad, put heat on high & start the car. Check fluid level again & refill. Good luck!

Follow the upper rad hose to the thermostat housing. Remove bolts from housing & tap lightly with mallet to dislodge from the gasket material. Clean both surfaces with scraper, install new thermostat & gasket & retighten. Make sure thermostat is seated properly & in the same direction as it was before removal. Good luck!

drain coolant,follow upper rad hose to thermostat housing,undo hose,therm.cover,take therm.out,clean mating surfaces install new therm.and gasket.

1.find out Location first.
2.remove thermostat housing.
3.remove thermostat old one & Refix New One
4.apply Selent for thermostat housing & refix.
