CAUTION
Ensure that the engine is cold prior to opening the cooling system or removing
the sender from the engine. The cooling system on a hot engine is under
high pressures, and released hot coolant or steam can cause severe burns.
- Disconnect the negative battery cable.
- Remove the radiator cap to relieve any system pressure.
| Fig. 1: The sending unit uses a push-on wire
connector. To remove, simply pull straight up from the sender
|
- Disconnect the wiring at the sender.
- Remove the coolant temperature sender from the engine.
To install:
- Coat the threads on the sender with Teflon® tape or electrically
conductive sealer, then install the sender. Tighten the sender to 107–143
inch lbs. (12–16 Nm) on Navajo/B Series Pick-up, and 57–82
inch lbs. (6–9 Nm) on MPV.
- Attach the wiring to the sender and connect the negative battery cable.
- If necessary, add antifreeze to replace any lost coolant, then install
the radiator cap.
