Customer Question

Hi, we have a 93 nissan d21 with a 2.4 at our shop. Our customer installed a new motor and water pump and drove it for a few months. He now has brought the truck to us and we did a head gasket replacement as well as a water pump(from Nissan) and thermostat. The problem is we have good gravity flow when the engine is not running but as soon as it is running nothing will circulate. We have blown through all the lines and bypassed the heater core and cannot find a restriction...any ideas?
Thanks,
Holly

Hello my name Jay and thank you for your question.

Has the radiator been checked? Also how are you bleeding the coolant system?
