-> routine coolant change including new thermostat & reverse flush...but I ff you dont have any fresh antifreeze handy it will be more than a tenner...(more like 15 - 20 perhaps)
Thermostat - £6 ?
Tharmostat housing gasket - £2 ?
Antifreeze - £8 - £12?
I think so
Definately. when the engine gets to normal temp..the thermostat should open to allow water to circulate around the engine and radiator (to keep it from getting any hotter than normal operating temp)
if the thermostat is jammed closed (often through crust build up) then the engine will get hotter and hotter ...eventually alliminum cylinder head will warp resulting in fluids & gasses escaping past the gasket....sometimes the gasket can break as a result of this too
