Got a new thermostat from Porsche along with a water pump etc.

The thermstat (TS) was without the housing and as I have been reading I may need a special tool the remove the TS from the housing?
Can anyone verify this?

I can buy an after market one from Pelican that has the housing as a single unit for about the same price. Which I will do if I need a special tool for this simple job

If the new stat is without a housing, yes, you will need a special tool to swap them around. Only Porsche sells the tool, for a little over $100; but you can make one from a hunk of pipe or tubing.............

Any write up on DIY?

Doesn't really require one. If you look at the thermostat, it has two "ears" that lock into the housing. Find a chunk of scrap tubing that fits over the stat down to the metal piece that the ears are part of, and is large enough in diameter that it just clears inside the housing where the ears sit when assembled. Cut of file two short "dog" sections into the tube that will align with the ears on the thermostat, removing the rest of the tube so that the "dogs" stick out of the end of the tube. File off any burrs you created, put the tube over the thermostat in the housing, press down on it and turn it until the "dogs" catch and turn the thermostat, releasing it from the housing.......

Wouldn't it be easier to notch the tube so it locks onto the ears?

Looks easy enough.
Looks like any tool that can fit in there you can push down and pop her out!

Thanks

That would also do it, but actually takes more effort to make. We fashioned ours after seeing the "real thing", and it works just fine.......
