Where is the temp sensor on a 91 Chevy astro
The themostat is located in the top rad hose on the engine side, but I don't know about the sensor. In my 91 the coolant temp sensor is in the thermostat housing and the engine temp sensor is on the block.
My 91 Cavalier (RS 2.2L) doesn't have one but my 95 does on the left side of the drivers seat.
It's in the distributor also called a hall sensor.
if it is the same motor yes, but some may have different mounts or wiring plugs
Need more information
Usually on most Vehicles the Crankshaft Sensor is located Behind the Lower Pulley which is known as the Harmonic Balancer.
There is no such thing!!
The starter on a 91 Chevy cav. is located at the lower front end of the engine. You can get to it better by jacking the front of the car and attacking it from underneath.
Perhaps it was hit by a meteorite. Check for fuel and spark.
The hydraulic clutch on a 91 Chevy Cavalier is bled by slowly pumping the clutch and releasing the bleeder valve. The valve is closed and the process repeated until all air is removed.
You won't find one. The 1991 Chevy S10 doesn't have a MAF sensor.
The intake rear...next to Alternator...This is what I have found out.
Bad heater core.
I have a '91 Cavalier 2.2L My flasher is located behind the fuse box to the left of the steering column. The flasher is mounted against the firewall.

If we are talking about valve lifters, remove cylinder head and pushrods and lifters will be excessable.
Some have it and some don't. My 91 doesn't but my 95 has it on the left side of the drivers seat.
I have a 91 s10 and it has a speed sensor. It is located at the rear of the tranny on the drivers side
Remove it from the car OR It can be flushed by a knowledgeable person with the correct equipment.
I would say you have to check your coil packs, and ignition module to see if they are firing on all cylinders, and have the correct spark. Anything but a bright blue spark means a weak coil. The ignition module can be tested at some parts stores.
