Leaking thermostat housing

OrangeInNE · Jul 19, 2009

Have a 47 C that is leaking coolant around one of the two bolts that attaches it to the cylinder head. Any ideas?

Thanks

If you can get the bolt out put a new copper washer on the bolt.

As Jeff say IF and that came be a very big IF. If you can not do so with out braking it which happens 75% of the time you can some times stop a leak like that with silicone sealer. Clean the area up real good then slap a good coat of silicone sealer on it. Nice thing is the silicone is easy to clean off when and if needed and will seal a good number of leaks like that

Goop Sealant and Adhesive also works real good.
You can get Goop at a hardware stores or Home Depot.
Cover the whole bolt head and surrounding area.

Thanks for the tips. Looks like the copper washer stopped the leak.
