Question about 1991 Cadillac DeVille
You need a special hose clamp remover to get the heater hoses off.Craftsman # 8-47390 about $45or$50 depending where you live.The clamps are way down in the engine bay between the strut tower and the firewall.This tool has a foot long extension that grabs and compress the clamp so you can slide it up the hose and away from the heater core.Without this tool I recommend you pass on this one.It's a simple core change with lots of room,I wish they were all this easy.Just remove the passenger kick panel and the housing is right there.7mm screws everywhere,just take your time and it should only take you 3 or 4 hours.Care needs to be taken when putting the housing back on,there are wires and vacuum hoses that will try to get between the two halves.Pinch the hoses and you'll loose control control of heating and AC.Good luck!
