Follow upper radiator hose to housing attached to block. On lower part
of this housing there is a multifunction sensor with a rubber boot with
4 or 5 wires sticking out , and a bronze or copper colored exagonal
shape. It is threaded to housing (normal thread direction).
With engine cold or lukewarm:
Run a small screwdriver carefully around the perimeter of the boot,
between the boot and the sender body. The intent is to separate any
Push down the boot from the upper edge and work it down. ( Do no pull
down the wires). There is a plug in connector inside with 3 or 4
contacts. The boot going down will disconnect the plug.
Prepare the replacment part next to you so that you don't have to walk
Place absorbent towel or rag underneath the sender.
Using an open end wrench loosen sender and finish extraction by hand
but maintaining slight upward pressure to avoid excessive coolant loss.
When sender completely loose, pull it out and plug opening with left
hand index finger.
With right hand ( quickly without panic) insert new sender and initiate
thread. Do not overtight with wrench. ( brass threads).
Re-connect plug redress boot and clean the coolant from the block etc...
Warm up engine check for leaks and enjoy your new temp reading and ECU

them a try.
Ask Jim to send you a copy of his periodic flyiers
