Questioni have a 95 cadillac deville 4.9 engine,how to remove and install heater core
AnswerHi Carl,
There really isn't much to it.
Remove the neg. battery cable
Drain the antifreeze into a clean container to reuse
remove the 2 heater core hoses
remove the glovebox
remove the lower sound insulator panel below the RH dash
remove the programmer
disconnect the body computor module and remove
remove the relay panel from the heater core cover
remove the cover on the RH end
remove the core attaching straps and remove the core
Then reverse the procedure to reinstall. If flushing the cooling system install 6 seal tabs after crushing them up. If just draining and installing new then 2 seal tabs. And if reuseing the original coolant then don't add any.
Hope that helps. Bill
