Valve Guides
Replacement (cont'd)
Working from the camshaft side, use the driver andan air hammer to drive the guide about 2 mm (0.1 in)towards the combustion chamber. This will knock offsome of the carbon and make removal easier.
CAUTION:
. Always wear satety goggles or a face shield when
driving valve guides.
. Hold the air hammer directly in line with thevalve guide to prevent damaging the driver.
Turn the head over, and drive the guide out towardthe camshaft side of the head.

It a valve guide still won't move, drill it out with a8 mm {5/16 in) bit, then try again.
CAUTION: Drill guides only in extreme cases; you
could damage the cylinder head it the guide breaks.
6. Remove the new guides from the freezer, one at atime, as you need them.

I7. Apply a thin coat of clean engine oil to the outsideof the new valve guide. Install the guide from thecamshaft side of the head; use the special tool todrive the guide in to the specified insralled height. lfyou have all 16 guides to do, you may have to reheat
the head.

Timing Belt
Removal
NOTE:
. Replace the timing belt at 105,000 mites (168,000 km)according to the maintenance schedule (normal con-ditions/severe conditions).
lf the vehicle is regularly driven in one or more of thefollowing conditions, replace the timing belt at 60,OOOmiles (U.S.A.) 100,000 km {Canada).. In very high temperatures (over 110"F, 43"C).. In very low temperatures (under -20.F, 29.C).. Turn the crankshaft pulley so the No. 1 piston is attop dead center (TDC) before removing the belt (seepage 6-57).
. Inspect the water pump before installing the timingbelt {see page 10-14).

1. As illustrated below, use a commerciallv available
air-impact valve guide driver attachment modified
to fit the diameter of the valve guides. ln most
cases, the same procedure can be done using the
sDecial tool and a conventional hammer.

Select the proper replacement guides and chill
them in the freezer section of a refrigerator for
about an hour.
Use a hot plate or oven to evenly heat the cylinder
head to 300"F (150"C). Monitor the temperature with
a cooking thermometer.
CAUTION:
. Do not use a torch; it may warp tho head.. Do not get tho head hotter than 300"F {150"C};excesgive heat may loosen thg valve seats.. To avoid burns. use haaw gloves whon handling
the heatod cylinder head.
