hey guys im now completly at a dead end. My 1978 300D non turbo is overheating. I have replaced the t-stat, water pump, brand new Nissens radiator. I have my climate control bypassed and just did a oil change with new oil pan gasket I know this doesnt relate to the cooling system but im throwing all my cards on the table.

At idle or while driving the temp guage just keeps climbing. The top radiator hose is hot, the lower hose is warm, the top of the t-stat housing is hot.


Any suggestions would really help me guys, like I said im stuck.
