Oil Thermostat o-ring replacement question

[keitho64]

I attempted to replace the o-ring on my oil thermostat last night. I removed the two 10mm nuts from the top but it did not want to come out. Is there another bolt holding the thermostat in that I am missing, or is it difficult to pull the thermostat out?

Before I take the brute force approach, I thought I would ask here. I could not find anything in the archives on this topic and according to my manual I should only remove the two nuts. I appreciate any ideas.

Thanks

when I replaced mine it didn't want to come up so I pryed it up with a short piece of wood. There's a "tab" where you can place something underneath and not hit the seal at all. After I got it started it was easy to pull out.

A couple of sturdy bottle cap openers under the sides of the housing should free it up.

While I wouldn't want to pry too hard, I assume you're replacing the O-ring. So don't worry about ruining that part. I used a very thin flat head screwdriver.

A right angle/offset screwdriver is great for prying in places like that. Sears has them for $2 (link to Sears Ad)

Thanks for all of the ideas. I figured that it was just stuck but I was reluctant to pry to hard unitl I asked.

Chris, I have one of the offset screwdrivers and will try that tonight.

Keith,

Might want to consider putiing some o-ring lube/sealant on the new o-ring to extend its life.

Popular choice is Dow Corning 111 or 112 Silicone Compound. 112 has a higher temp. rating and would probably be the way to go.
