M1008 - wrong thermostat housing?

[Commander5993]

Hey all, I've had an issue with my belt moving/bouncing enough that it is able to touch the bottom side of the top radiator hose to put some marks in it. Tried to take a couple pics of where its hitting and of the thermostat housing.
Where it bumps the hose it hasn't made a deep mark, but obviously it will eventually cause a leak. Belt is tight, just the normal amount of tension movement, about 1/2" up or down. I actually tightened it to try to stop/minimize this. For the time being, I actually took a couple large zip ties and was able to pull the hose up just a bit to stop the belt from bumping it. But I'd rather find a "proper" solution.

Seems like the thermostat housing should be at a 45 degree angle upward or something. Instead it just points straight out from the engine putting the hose down to close to the belt. Anyone know if this is the correct housing? Or if there is another thermostat housing alternative??

Thanks!

The original upper radiator hose clamp at the t/stat housing will have a stainless steel deflector/guard that is part of the clamp assembly. This deflector essentially covers the bottom of the hose that can come into contact with the driver's side alternator belt.

Faststandard is correct, you are missing your guard, your belt might need to be tightened. They do sell a belt gauge. I would snug it up until you remove most of the wobble in your belt.

Thanks guys, never knew there was supposed to be a guard there. Wouldn't have even thought about it. Will look and see if I can find a guard.
I may go ahead and replace the belt again. I replaced it once already, and it still looks basically new, not worn. but I've already got it pulled as far as it will go trying to keep it from touching.

Take a tin can or a piece of aluminum and use a second hose clamp to put a curved metal guard in place. You can fix that easily. And if t=you watch it only bounces up and hits that hose at idle and rapid deceleration. But yes the guard needs to be in place.

Hey Cucvrus I actually had found and ordered the correct part (and a couple other things) on hillbillywizard.com before I saw your reply. But your suggestion would have worked just as well. After finding out there was supposed to be a guard there, I had considered just making something to shield the hose if I hadn't been able to find the correct clamp.
And yes I thought it was only bumping at idle (didnt think about during deceleration though, but makes sense), as I figured under load the belt would be taunt. And also the belt would have worn through the hose fairly quickly if it was bumping it all the time.
