Default quick thermostat question

I just need to know if there is a specific type of thermostat I need for my miniram. Mine went out today, spewed some coolant out the resovior and got up to 262 degrees , no damage though. It had a 180 degree thermostat in it, but I've heard of needing a special tstat for minirams. Any ideas?

I'm sure this will be interesting. I like a 160 thermostat. It works well with my superram. Why would the miniram require a certain thermostat?

It appears to be quite thin compared to the stock style intakes. Over on thirdgen.org (f body forum), I've heard of the t-stat bottoming out on minirams. I guess I'll just throw a 180 in, but would a 160 be better? Wouldn't mess with the computer or cause the car not to get to proper operating temps would it?

Check out the link. If the 180 worked well stick with it. I live in a hot climate.

Some people had trouble here on this Forum too. I think it was early castings of the Mini Ram that had the problem. You can take the old one with you to compare, right?

The mechanic said it looked like a standard thermostat, so he threw a 180 in and everything is great. It occasionally was getting hot, so hopefully the thermostat was the issue.

I have no idea what car you have, but a quick check on the TPiS site says they rec. 170* on L98's and 160* on LT1's. Not that I agree with that, just passing it on. It would be helpful if you would fill out your profile or identify the year.

I drilled holes in the thermostat today and the problem is now solved. I guess I just had a nasty air bubble under the tstat. Also, the tstat isnt bottoming out, the miniram is the newer style with the recess being in the water neck.
