    (95 3500 5.7) Anyone happen to know the thread diameter and hose size? I would like to remove & replace with just an ordinary old school set up rather than the crappy design thats on it.

    1/2 inch pipe thread. Most any auto parts store should have adapters for 5/8 and 3/4 hose.

    Pretty sure it's 5/8 from the manifold to the heater core, probably 3/4 from the core back to the water pump.
