Ok, Ive been swapping out the sensors on my engine, and since there made of plastic, and are prolly 20 years old, some of them broke. I broke 3 of them i think.

1. The sensor under the passenger side exhaust, had a blue plastic piece on it.

2. The sensor on the intake manifold, in front of the heater hose inlet. It has two tubes on it.

3. The sensor on the driver side head, underneath the exhast manifolds.

Any replies will make it easier to track these sensors down, thanks.

 

1. If it's in the block above the oil pan, it's the knock sensor. If it's in the head, it's the coolant temp sensor.

2. Thermal vacuum solenoid

3. Coolant temperature gauge sender, or idiot light switch.
