I change the water pump after I change the
thermostat I bleed da system got heat sat for
a hour then drove off I say bout a half hr later

Radiator hose was mad tight like it have air in
it still I don’t know how an what to do to find
out if it’s Clogged up or not also check
engine light on for the Catalytic converter
could that be a problem for overheating
