Thanks for all the replys.The WP was a Graf and thermostat was Behr 87C.I think I got all the air out from the system and now it runs around 90C-95C outside temp. is 30F.The car ran just a bit past the 80C mark before.I'll put back the old thermostat see what happens its 10min job.

thanks in advance
