Coolant Leak 351W
 

Experiencing Coolant leak with the cold nights here along the NC coast. Hoses are new, pressure tested with no leaks. When the truck is warm, no leak, only leaks when the temps drop below 40 at night. I have researched that there are some seals at the water pump and even the timing cover that may need replacing. Any other ideas or experiences?

The truck is an 88 F350 with the 351 Windsor. We are the second owner. Purchased from a Fire department with just north of 19,000 documented miles. The age of the parts have had us replacing them over the last year.
