The thermostat is located between the water outlet and a housing built into the intake manifold.

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

REMOVAL:

Disconnect the negative battery cable.
Remove the air inlet duct.
Drain the cooling system to a level below the thermostat.
Remove the thermostat outlet-to-engine retainers (usually either 2 bolts or 1 bolt and 1 stud), then remove outlet from the intake manifold.
Remove the thermostat from the housing, noting the orientation for installation purposes.

INSTALLATION:

Carefully clean the all traces of the old gasket or sealer from the housing and outlet.
Install the thermostat to the housing, oriented as noted during removal, then position a new gasket (if used).
Place a 1 / 8 in. bead of RTV sealant in the groove on the water outlet sealing surface, then install the outlet while the sealer is still wet.
Install the outlet retainers and tighten to 14 ft. lbs. (19 Nm).
Properly fill the engine cooling system and check for leaks.
Install the air inlet duct.
