Where is pump located and what test can I do to the pump? Thank you again for the help
The test for the pump is to (see) the water in the radiator to (see) if it’s circulating. If it just sits there after being warmed up to normal operating temps the water will be visibly moving. If you watch constantly from the start you can see the water moving right at the moment the thermostat opens. The level will drop and then ‘refill’ as the engine water circulates back into the radiator (if) the pump is working. Otherwise the overfill tank will fill and then overflow.
