Im losing coolant. Cant find obvious leaks, oil looks great, and truck runs fine. Must be losing it while on the road. Is only way to test stationary with a pressure system?

Use a flashlight and look at the upper and lower radiator hoses, where they connect to the engine. look for white crust , thats evidence of a leak. If the connections at the engine side of the hoses are black plastic, instead of white/yellowy plastic, then its prolly radiator hoses leaking. The black plastic tips are an outdated single-o-ring design. Also, look at the radiator at the bottom, on the driver's-side corner. Thoses 3 things account for like 95%+ of coolant leaks on these trucks.

well i took my truck into the dealer and they said my upper / lower rad hoses need to be updated and my radiator has a leak... idk how it has a leak but not visibly leaking..
not the head gasket or water pump.. about $2,150 to replace rad and hoses, dugas bottle n hose plus the fluids.. the price for the oem radiator is $800. so at that price i might just go buy an aftermarket and do the work myself..
