I may have a leak at the hose(s) that connect to the cooler, and it only leaks at higher speeds?...thanks for all you r help.

Answer
I'm sure that the fluid pressure is higher at higher speeds. Note: The pump turns at the same rate that the engine does, not at the rate of the drive shaft. I don't think that the pressure will be more than 30 psi (give or take a couple of pounds). It is very possible for a hose to leak at high rpm and not at high rpm. See if you can clean things off under the truck. The most likely problem is a leaky hose or a loose hose clamp. Congradulations on getting it in.
