I changed waterpump yesterday on 02 dodge caravan. temperature gauge spikes to Hot very quickly- Is it necessary to bleed air fr.line in this situation? also where is bleeder located? Any thoughts??
I don’t know that the Caravan has an air bleeder valve, did you set your heat control to hot and run the engine with the rad cap off ?
what engine do you have in this caravan?
why did you change the water pump in the first place? what made you suspect you have a problem?
is the change in temp spike the same both before and after water pump change?
has the engine loosing coolant? before the water pump change?
