01
Remove the coolant overflow (radiator supply) tank. To
squeeze this tank out from under the fender it was nec-
essary to loosen the air-conditioning compressor adjuster and
swing the compressor inward, toward the valve cover.
03
A 1 1/16-
inch
wrench or large
adjustable
wrench is needed
to remove the
largest fittings on
a VIR, plus a mix
of wrenches from
3/4-inch to 7/16-
inch to discon-
nect the other
hoses and tubes.
Fortunately, they
shouldn’t be very
tight because it’s
the O-rings that
accomplish the
sealing.
02
Remove the right splash shield for access to the VIR and
the lower side of the evaporator housing. You may need
to remove the three forward screws on the rocker molding and
pry it out a little to access the two outer bolts. In addition to
repainting, this shield needs the rubber molding that was sta-
pled on its inner side.04
The evap-
orator
housing (cover)
is attached to the
blower motor
housing with
five screws. Tip:
tighten each
screw first to
see if the fiber-
glass screw hole
is stripped in the
evaporator hous-
ing. If so, you can
repair it after
removing the
housing.05
The stud holding the
evaporator housing
to the firewall is the easiest
attachment point to access.
Unplug all the wires on both
housings, don’t worry about
labeling them; they’re differ-
ent for each component so
there is no worry about plug-
ging them back in incorrectly.24 VETTE 19.07
