serial # 0C145238
I noticed water coming out of COVER ASSEMBLY, Cylinder Block by #1 spark plug. the previous owner had applied silicon where the gasket was leaking.
while removing it i broke a wire coming off some type of sensor located next to plug #1 the cover has an opening made to fit around the sensor and plug #1.
Could some one please tell me what is the name of the sensor and what does it do, i grounded the wire with motor on and it kept on running,, with motor off and ignition key on and i heard something making a very slight noise when i grounded the wire...... also i think the motor is an 89 but would some one know from the serial # what year it is??
