[s-cars] New Brand of Thermostat - Beware!

[Tony Curran]

Just as winter was setting in I changed my thermostat. The online parts
supplier I use sent a new brand called Calorstat.see link.

I was then plagued by a very small coolant leak over the winter which I
traced down to the thermostat housing. This Calorstat thermostat is somewhat
different to the Wahler unit and I suspect the housing did not apply
pressure to the thermostat sufficiently - inside the hosing there are two
pillars applying pressure to the thermostat - hence leak. Re-installed a
Wahler unit and no leak.

 

So please head the warning and stay with Wahler!
