Vette Coolant

This bulletin applies to 2016-2018 Chevy Corvettes equipped with a 6.2L LT1 or LT4 engine. A vehicle may have a concern with coolant loss and/or coolant odor after driving the vehicle.

If the coolant is low, pressure test the system looking for leaks at the outer head bolts.

If a leak is found, the cylinder head with the leak should be replaced.
