Volvo Maintenance Hints for 7xx/9xx - Bill Garland's Nuclear ...

top -a diagram really helps here). Separate the cover from the box by prying with a blade (putty knife) inserted into the
mastic (starting at the lower right and prying up the right seam) allowing you to remove the cover by hand (don't be too
forceful once you get it started in case you've missed a screw). Note the locations of the four coloured vacuum servo
hoses connected to the cover then remove them (unclip the tab then slip off).
15. Remove heater core: simply held in by the two long side clips.
16. Mop up spilled anti-freeze: The tunnel carpeting, passenger footwell and left rear footwell are the prime target areas.
Extract the excess from any soaked carpets (a carpet shampooer is ideal; a wet/dry vac is the next best; blotting with old
towels will do; rinse and repeat). Peel up all wet carpet areas, blot up any excess including foam side of underpad). Leave
carpet up until areas are dry. Dispose of liquid anti-freeze and contaminated rags properly.

Total time for removal is somewhere in the 5-10 hour range. Replacement heater cores are available from Volvo (p/n 1308374,
for all 700/900) and on-line from places like ipdusa.com, AllOEMVolvo.com, carparts.com and global4auto.com. Brands are 4-
Seasons (variously as p/n 94734 and p/n R3000-62353) and Everco (p/n H5121) with prices between U$100 and U$250. Used
heater cores are probably NOT a very good buy when you consider you're paying the labour to have a used one removed and
the labour you may soon have to repeat if it also fails.
