what engine? most will be close to the t-stat.
On a 1993 buick regal it is on the side of the radiator.
The 1992 Ford F2 50 pickup truck 5.8 liter engine coolant temperature sensor can be found on the top of the engine. The coolant temperature sensor will be near the intake manifold.
I don't know but I would like to know as well.
on the thermostat housing
Located on the bottom left side of the radiator, next to the lower hose. There are several sensors on the 1.5 liter. The engine coolant temperature sensor you're referring to (I think) is located in the intake manifold, at the left hand side of the head. I always get the guage sender and this coolant sensor confused, they are adjacent to each other. Unplug one then check your guage when engine is hot, this will cause the guage to fail to register a temp, and you can identify the proper sensor.
The temp sensor switch is located on the right side of radiator ,at the bottom.
they are located near the front engine
The 1992 Chevy 5.7 liter engine IAT sensor can be found on the back of the engine. The IAT sensor will be near the top of the transmission.
There's no such thing as an "L7" engine
in the dist.
The coolant temperature sensor, which is located behind the engine block near the firewall, senses when the coolant temperature reaches a predetermined temperature so that the transmission can shift into overdrive. This sensor and the hose preceding it can get gunked up with cystallization from the coolant (red Toyota coolant is notorious for doing this) and can prevent proper flow to the sensor i.e. your transmission may take longer to shift into overdrive or may not shift at all depending on how constricted the hose is.
To answer this i will need to know whatsize engine you have.
