okay so when you say it doesnt seat right, are you talking about the gap it leaves for the bolt? i got new bolts for this and the left side gap make it to where the bolt isnt long enough to screw in, i couldnt get the old ones back into because they are stripped

Glad it was helpful!

I had similar issues; I broke the ear off twice before I realized it does not seat. If you tighten the allen head bolt all of the way you will absolutely, break the ear off. I put a thin shim between the thermostat housing and the water pump housing on the allen head bolt side. This has been very frustrating. I also found that there must be a couple of different designs because I bought the thermostat separate from the housing it rattled when assembled. I found 2 different stem lengths. When assembled with the hose to the housing off, push up on thermostat with your finger to see if there is excessive slop, basically see if thermostat moves up and down easily. not talking about compressing spring. I recommend buying the kit that comes with housing and thermostat.
