I do not know your rig!

If yours is the "TYPICAL" thermostat set-up

Follow your upper radiator hose, it normally connects to the thermostat housing----this is what you will be dealing with.

Insure the engine is cool, drain about 1/2 gallon out of your radiator.

You may or may not have to remove the radiator hose off of the housing.

Next remove the bolts holding the housing to your engine. Pull off the housing. Observe the old "Stat". It should be POINTY side up, and the spring side toward the engine (hid inside the hole). OBSERVE THE GASKET. Which side of the "STAT" is it on? THIS IS IMPORTANT!

Clean the housing surface, and the engine surface.

INSURE YOU HAVE THE CORRECT TEMPERATURE THERMOSTAT. OTHERWISE YOUR RIG WILL NOT GET TO THE CORRECT TEMPERATURE FOR THE COMPUTER TO WORK CORRECTLY!

Install the GASKET OR THE STAT---OR REVERSE--HOWEVER IT WAS ORIGINALLY!

Then install the other!

(I use "INDIAN HEAD" gasket shellac on the gasket surfaces, you do not have to!)

Next, install your bolts. They should be torqued to specs. Tighten evenly!

MAKE ABSOLUTLY SURE THE "STAT" REMAINED IN IT'S RECESS. OTHERWISE IT WILL STICK OUT AND YOU WILL BREAK THE HOUSING OR CREATE A LEAK 'CAUSE ITS KEEPING THE HOUSING UP IN THE AIR!

If you have no specs. My rule of thumb is to :

Use a 3/8 drive ratchet

Wrap my palm over the head of the ratchet.

Let the side of my "PINKY" push on the handle part, then Torque it as hard as I can. Within Reason. DO NOT LEVER WITH THE HANDLE. You will strip it, or break the bolts!

RECONNECT YOUR RADIATOR HOSE!

FILL YOUR SYSTEM UP WITH RADIATOR JUICE!

MAKE SURE THE DRAIN IS CLOSED!

FIRE HIM UP----WATCH FOR LEAKS!

REACH FULL OPERATING TEMPERATURE----CHECK FOR LEAKS!

DRIVE A WHILEWATCH THE TEMPERATURE GAUGECHECK FOR LEAKS!

YOU ARE DONE!

AIRBORNE!

Now, if your system is not like this, disregard the WHOLE DEAL!

Come back and give me some GOOD NEWS!("Feedback" is cool too!)
