Need to change hose connected to t-stat housing

[LiqTenEXp]

Hey,

I need to change the section of coolant hose that connects to the thermostat. It is the one near the upper radiator hose. What is involved with changing this hose?

a 5/16th nut driver for the clamps and some elbow greese.. if you absoltly have to take loose the t-stat housing becarefull not to rip gasket . and be aware if you do take loose stat there well be alot of coolent everywhere . so have BIG drop pan,,

I have sets of hoses, top, lower, the ones behind the oil filters, the little ones on the water rail. $35.00 plus shipping. PM me if interested. You can loosen the upper radiator support and the upper hose comes out and goes back on easily.

It's the bottom one that'll make a preacher cuss.

The picture below shows the hose I am looking to replace, it comes off the water pump and into the t-stat housing. You sure I can replace this without pulling the t-stat housing?

If I do, I may as well do the upper hose. Just wanted to know what gaskest are required to r/r the t-stat housing if it needs to be pulled.

I just did this the other day. It really wasn't bad but it is a big mess, you will need a big drip pan. I pulled the radiator support brace off first. I think 2 1/2" wrenches, and 2 9/16" wrenches. After that I loosened all the hose clamps. (Well actually slowly one at a time to catch as much of the antifreeze as possible.) Then I took off the thermostat housing bolts, 9/16" I believe. From the it is pretty much self explainitory. You need about 1 foot of 2" I.D. coolant hose. I got it from O'Reillys for 9.** $ a foot. I cleaned up the water pump neck and put on the bottom hose. The put the thermostat housing back on. I cleaned it real good with some scotchbrite and the used black rtv silicone to seal it up. I used alot, I didn't want any leaks. Then I put on the upper radiator hose. Easy as cake. Just time consuming draining all the coolant in the cleanest manner. I have put a 100 miles on mine since changing them and I have no leaks. Except for a small water pump leak. Now the lower radiator hose on the other hand is a god awful nightmare. Hope this helps. Holler at me if you have any questions.

was there a gasket between the t-stat housing and the block and you just replaced it with lots of rtv?

Actually there was no gasket. It had black RTV on it. And that was from the military. But RTV worked just fine. I use some expensive stuff. Its "The Right Stuff" it comes in can. It works great. I have had no problems and in several situations I have used RTV in place of an actual gasket with no ill effects.
