I have discovered leaking coolant coming from the heater core hoses. Do I need to drain the coolant to replace these hoses? Any other hints would be appreciated

Thanks

Yes, you have to drain the cooling system. Well, actually the choice is to drain the system INTENTIONALLY, or to pull the hoses off first and take a bath in antifreeze. Personally I prefer the former.

Or use a pair of vice-grips, one on each hose.

Problem is that many of these hoses are ancient and the vice grips may crack what you have.

Like Walter says, drain it first. Even then you'll have some spillage onto the floor, so keep some rags handy.

Thanks for the advice.
