I'm in the middle of changing all my belts, hoses, radiator, and adding a tranny cooler. I need help with a few things: 1. The stock heater hose from the heater core to the top of the intake has rubber then crimped onto metal piping. Should I remove this whole piece off the intake, cut the metal part with a tube cutter then reuse it to connect the new hose to or install some type of new fitting on the intake which I can run the new hose to? 2. The t-stats available were 160, 180, 195. I p/up the 180deg t-stat... Is this the right one for an '88 with all options? 3. Should I put a sealant on both sides of the t-stat gasket before installing? 4. How do I remove the crusted rubber off the heater core fittings?
