Q: Screw broke on manifold

asked by on

A screw broke on the manifold where the thermostat goes, and coolant leaks out.

Hello. It is possible that the broken screw could be extracted and replaced. This however, may or may not be possible. If it is not possible to extract the broken screw you would then need to have the entire manifold itself replaced by a certified technician. I would recommend having the mechanic inspect your coolant leak and determine the best fix for the screw problem.
