Thermostat
So I picked up a thermostat from Mark H. It doesn't stay put in the housing like it should. Is this normal? It's marked as 44MM.

Re: Thermostat
How do you mean? Rubber gasket should fit into recess machined on lover side of the housing. I make small adjustments with a small flat head screw driver as I close up the housing halves to keep the gasket from being pinched.

Re: Thermostat
My mechanic says when he installs it that it falls out. He says it should stay put until he can install the housing over it. I didn't see it in action, so can't comment a lot.

secondchance has about as good advice as any I have seen I use a putty knife also just to keep the thermostat gasket from being pinched. If the two halves of the housing mate up tight with just finger torque on the bolts you know you have not pinched the gasket.

Installing the Thermostat and New Short Hose to Radiator
Quote:
1. Separate the thermostat housing half that bolts to the frame and remove it (with bracket) with the old short hose (use razor blade on that hose lengthwise if you have to remove it from the radiator Connector). 2. If you are using Silicon Hose it will be hard to slip on the Thermostat Housing and Radiator Connectors but with a little permatex it can be done fairly easily. 3. Slip that hose onto the thermostat half first with the thermostat half in hand. 4. Then with a bit more permatex on the radiator Connector, push the hose (attached to the thermostat housing half you removed) on that connector to a depth such that the thermostat housing half lines up perfectly with the mating surface of the other housing half that you stick the thermostat into (the thermostat housing half you did not remove). 5. Tighten hose clamps AFTER (See B Below) you get the two thermostat housing half bolts installed and tightened (including the short bolt through the Bracket and including the Bracket bolts to the Frame. 6. Make sure you put the short bolt that just goes through the bracket in the correct place in the threaded hole on the thermostat housing half you removed. 7. install the two bolts vertically securing the thermostat housing bracket to the frame. B. Lastly......tighten the hose clamps such that the clamp is just inside the raised ring on the connectors to make sure the Silicon Hose does not slip off (especially if you use Permatex) before the Permatex cures. C. To put this in perspective all in one post You install the Thermostat immediately after Step #4 above as follows Quote:

Re: Installing the Thermostat and New Short Hose to Radiator
Dynomite,
Thanks very much for posting the steps below. Very handy. I'm convinced the hoses I took off tonight must be original. Big struggle to get them separated from the pipes. Afterwards I had to spend awhile with a wire brush (powered) to get all the old stuck rubber off. The top pipe is painted (and drying), and when I put it back together I'm planning to use some water-soluble oil to help the hoses slip on. I noticed you mentioned Permatex. Is that as a sealant? I don't think I've heard of that before. I also plan to ditch those terribly unfriendly stock hose clamps. I just don't understand them. They must be a cost saving thing. Russ Quote:

Re: Thermostat
All done. The new red hoses look great, and he put them on with black heat shrinks instead of clamps. I gotta buy a lift, I think I've paid for it with his labor.
