Hi all,
Very recently my thermostat has stopped opening. Ive tried taking it out and boiling it and it opens and closes smoothly and at the correct temperatures. The Coolant hose coming off the T-stat is staying cold but the Temp at the coolant sensor has hit about 230F. Also i tried bleeding the system with the car on ramps and the T-stat opened fine but on the road it is refusing to open. Anyone have any advice?
