Hello all,
My '08 smart keeps over heating and I've hit a little road block. I've replaced the water pump, water outlet tube that connects to behind the water pump, and thermostat. When the coolant cap is on tight coolant won't flow through the system, it's when I loosen the cap is when I get coolant to flow through the system. I can't get the heat to work. No milly oil, and no white smoke.

Please help and thanks in advance :)

Are your radiator fans turning on in time? Is your coolant new? Is it full? Have you bled the cooling system after the work? You may have an air pocket causing rapid overheating.

Fans turn on at 210 degrees, new coolant and I've attempted to bleed coolant but not sure if I'm doing it correctly

I bled as follows:


jack up front of car as high as possible, fill coolant, leave cap off, partially remove coolant hose from rear of cylinder head on engine. I had to remove the hose a couple times till I got all air out

If you don't get heat, that sounds like a air bleed issue. Also there was some problems with the water lines under the car being pinched off just to the front of the engine compartment
