Thermostat Replacement?

[Captain]

I just replaced my water pump on my 1999 996. I was wondering if I should have replaced the thermostat as well? I'm a bit concerned that I did not.

Thanks,

Harry

Strictly speaking it is not necessary if the engine temp. act still as it should, however, after 10 years i would have done it to be sure, it's not much more work and not expensive.

Harry:

It's only four 10mm bolts, one radiator hose clamp, and a partial coolant drain to replace the T-stat. If you have tackled the water pump yourself, it should be an easy DIY for you.

If you are only replacing the T-stat, I understand that a special tool is required to remove the T-stat from the housing, but IIRC the tool can be improvised.

When I replace my thermostat it will be with 160 degree version from LNE that comes ready to install w/o need for a special tool. Also plan to change out the "lifetime" fluid while I'm at it.

How to improvise the thermostat tool? Does anyone have pictures?
