Hi All,

I didn't want to tack this post onto a stale heater core post about how to
replace a heater core.
Plus, it's more than disappointing that the original poster never came back with any comments.

I had a hot foot with live steam from an 850 heater core letting go,
and it was getting my right foot at the gas peddle, OUCH!

Luckily I was close to home, but it could have trashed all plans if on a trip
somewhere.

I made a clamp to squash the heater hoses to run the car while ordering parts etc., but a good pro-active solution for all Volvo's is here:

Have these in your car so you can drive along after the heater core dies.

Do you need to clamp both hoses, or will one do it?
Dunno if one clamp will do both heater hoses?

Happy motoring, Bill
