I'm having an issue where I'm losing coolant from the reservoir it steams or spills past the cap. I have replaced the tank and the cap but it still steams out or spills out at hard throttle. It is not a hose I've watched the steam come out and I've tightened the cap as much as possible. Any ideas of what may be causing this? Radiator was replaced recently.

 

Anyone?

 

Check your oil for coolant. Reverse flush the cooling system. Replace the thermostat. Compression check?

 

Sad to hear but here you go:

Sounds about the same but there it's no oil inn the coolant thermostat and temp sensor were replaced

 

Would K&W possibly work if it is the gasket?
