thank you for the response - I tried holding the upper radiator hose pinched and folded together while engine was running at operating temperature,there was no pronounce or force of pressure felt. do it suppose to build up pressure while holding the hose together. I PROBABLY NEED A WATER PUMP. thanks for the reply -
