Guest Bill Anderson Posted July 22, 2009 Report Share Posted July 22, 2009 Mist comes through vent whe heater is on. Th oolant level goes to minimum eah day and has to be refilled. I'mthinking the heater core but the coolant going down quickly heat on or not still is a major concern. Help?? Link to comment Share on other sites More sharing options...
VolvoEd Posted July 22, 2009 Report Share Posted July 22, 2009 Almost certainly heater core. You need to get that fixed especially since it seems to be a very bad leak, losing a lot of coolant like that. It's an easy DIY job. I replaced mine not too long ago. Is your floor under the mat wet too? You can get the part on eeuroparts.com or fcpgroton.com Write-ups on how to fix here: http://www.volvospeed.com/vs_forum/index.php/topic/9717-pics-of-heater-core-install/page__hl__Jeater And this is my very brief explanation from another forum of how I did it on my 2000 V70XC: "You have to clamp off the heater hoses in the engine compartment, pull the carpets back, remove the plastic shields (slides out, super easy), take out the screws around seam of the heater core box, undo the main screw attaching the core to the pipes, wiggle out the old one (some coolant drains here, have a plastic bag), replace the core and put it in the way you took it out. Took me about 5 hours, but this was my first decent car surgery and I was taking it slow. If I had to do it again, I would guess I could do it in under an hour!"

Can get messy if your not careful. Dont be cheap. Buy an oem core from Jamie ar DW Volvo Make sure to get the new o-ring seals too. I dont remember,but I think it comes with them.
