REMOVAL & INSTALLATION
CAUTION - Properly relieve the fuel system pressure before disconnecting any
lines.

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 409
When servicing the engine, be absolutely sure to mark vacuum hoses and
wiring so that these items
may be properly reconnected during installation. Also,
when disconnecting fittings of metal lines (fuel, power brake vacuum), always
use two flare nut (or line) wrenches. Ho ld the wrench on the large fitting with
pressure on the wrench as if you were tightening the fitting (clockwise), THEN
loosen and disconnect the smaller fitting fr om the larger fitting. If this is not
done, damage to the line will result.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.

and measure the end clearance. T here should be 0.0015-0.0050 in.
(0.038-0.127mm) between the thrust plate and the camshaft.
If the clearance is less than 0.0015 in. (0 .038mm), replace the spacer ring; if
more than 0.0050 in. (0.127mm), replace the thrust ring.
