Runs 170-180 all day long in city. Say below 55. Goes to 220 and probably would go higher if i let it over 55 mph. 50/50 mix coolant. Just changed radiator cap, of course it won't be that easy. Timing set at 10.5 btdc. 12 is too much. Thoughts ?
How old is the water pump. If it's old/worn those can be a cooling issue as they will cavitate more than pump.
