where is the water temperature sender unit on a ford puma
1990 Chevrolet Lumina temperature sender is located on the back side of the thermostat housing. The sender has a wire that goes to the temperature gauge.
Ummmm, Radiator fans run off a temperature switch. Sometimes they put the fan switch and sender for the gauge together so I suppose it could be related. Have you checked to see if the wires are unplugged? Just a thought.
temp sender located
this could be a faulty temperature sensor or a faulty fan switch from the temp sender
Where is the water temperature sender 1995 ford ranger 2.3?In: Ford [ranger]
On a Ford Fiesta 1.25 Zetec, the temperature sender switch is typically located near the thermostat housing. It is usually found on the engine block, close to the water outlet. You may need to remove some components for easier access, depending on the specific layout of the engine in your model year. Always consult the vehicle's service manual for precise locations and guidance.
follow the top radiator hose to the engine block. the temperature SENSOR has two wires. The temperature SENDER has one wire
Either an air lock or a faulty switch at the stat. If its not using water i would replace the sender (switch). Hope this helps.
Add a tee to the sender and put a guage in the tee . This will tell you the on and off points of the sender .
Chevrolet had a problem with it's combination sender/switch units used on the 350ci (5.7L) TBI engines in full-size trucks and cars between 1990 and 2000. The sender becomes inoperable due to a loose wire inside the sender itself and makes the gauge erratic. The fix is to replace the sender/switch.
