HOT WATER VALVE
REMOVAL & INSTALLATION
Not all model years and engine applic
ations use hot water valves.
1. Drain the coolant.
2. Disconnect the vacuum hose at the hot water valve by sliding the tab of
the connector past the L-shaped bend in the ac tuator vacuum tube.
Then, slide the hose connector off the tube while continuing to hold the
tab back against the connector end.
3. Disconnect the heater hos es from the valve.
To install: 4. Install the valve with the vacuum actuator faci ng up. The heater hoses
will hold the valve in position.
5. Install the vacuum hose to the actuator.
6. Refill the cooling system. R un the engine long enough to purge any
trapped air, then add more coolant if necessary.
7. Check for leaks.

INTAKE MANIFOLD
REMOVAL & INSTALLATION
When servicing all vehicles, be absolutel y sure to mark vacuum hoses and
wiring so that these items may be properly reconnected during installation. Also,
when disconnecting fitting lines (fuel lines, power brake vacuum lines,
transmission and engine cooler lines, etc.), always use two flare nut (or line)
wrenches. Hold the wrench on the large fitti ng with pressure on the wrench as if
you were tightening the fitting (clockw ise), THEN loosen and disconnect the
smaller fitting from the larger fitting. If this is not done, damage to the line will
result. Always relieve fuel system pressure before disconnecting lines.
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.
