I'm looking to flush my radiator and I figured I would also replace the thermostat.

Who makes the best thermostat for the price?

GM.

Is there a problem with the one you have? If not, I would just leave it.

A failsafe thermostat if your going to replace it. Most stats fail closed, you want one that fails OPEN in the event of problems.

I'm looking to upgrade it to a 160 or 180 degree.

I have used SLP and hypertech. Is yours just the stat or does it require the housing with the stat? I have a new 160 SLP stat that a friend never did pay for but it's just the thermostat. I know 2000 has the stat and housing togethor but I don't know about the 01 and up.

You can also add a shim to your factory thermostat, and make it start to open 10-15 degrees sooner.

Link to thermostat mod

As a follow-up to that link, I ended up putting in the shortest shim that I tested. In cold weather the motor runs at around 178 degrees (maybe down to 176 coasting down a hill). I think it will run in the low 180's in warmer weather.

I did the same thing as you. In late November, I was seeing coolant temps. in the mid 170's, with a .100 shim in my factory thermostat. I reduced the shim thickness to .050, to bring the temp. up about 5 degrees.

I've found that the stove top method of testing will get you in the ball park, but it takes some actual driving to determine the end result of the added shim.

I haven't road tested yet with the .050 shim, but I think it's going to be just about right.
