I recently replaced my water pump and thermostat and now I’m exceeding over 210* F. Any suggestions what’s causing this?

Hello,

This could be a problem with an air pocket. Air pockets will keep the coolant from circulating, creating hot spots. I have included directions for coolant filling in the diagrams below. Get back to us with what you find out.

Thanks,
Alex
