anyone got any experiences or advice on this??

i am thinking of removing the thermostat from from my Focus RS, in order to free up the water flow and reduce the temps when driving hard.

i always warm the engine up and wait for it to cool down before turning it off. the car isn't an everyday car.


what are the pro's and cons and is this a bad idea?

the ford plastic thermostat housing these things use are total dogsh*t. i am fed up of them. over time they crack or leak due to not being able to cope with the temps of a FRS imo. and i am sick of fixing the problem


my thinking was....

remove the middle of the thermostat so there is still some water restriction but will allow much better flow of water to the rad.



anyone got an opinion on this or experienced with zetec's etc and has done this?

Don't even think about it. The stat also acts as a flow restrictor, which, along with the water pump, generates water pressure in the engine. This pressure greatly improves heat transfer from the engine to the coolant. If you run with no thermostat, not enough heat is tranfered to the coolant, and the engine runs hotter, but the coolant temp will read lower on the gauge.
