There are a few things that can cause a clicking.. first is valve tapping which is when the valves become a little loose and the noise you hear is when the gap is taken up and the metal taps, second is that the bearings in your water pump may be starting to fail, and third might just be that your belt has a bad spot and clicks as it passes a certain pulley.
It is not supposed to be on when engine is running unless there is a problem.
Where is the clicking coming from? Within the engine compartment or inside the car?
If clicking while trying to start then might be a bad starter. If clicking while running, then might be valve/lifter noise.
A clicking noise in the engine of a 91 Ranger could indicate a problem with the valves. A valve lifter in the engine may be worn or stuck.
It does that when the engine is cooling off. It's called expansion and contraction.
there is a clicking noise when I start engine starts no problem just curious of the clicking noist
Look at your AC pump, and start your motor and turn on your AC. Listen for the clicking coming from the pump. That is you clutch cycling on and off for the AC. If that is the noise you are hearing then your good to go. If not then you will have to look else where, BUT BE CAREFUL when the engine is running.
Location of clicking sound not stated but: My 95 S-10, 4.3L engine was clicking when it was running. Turned out to be the fan tapping against the fan shroud, motor mounts were wearing, causing fan to hit this shroud. This may be your problem but you didn't state what area of vehicle sound comes from.
no as long as the engine is running the pump needss to remain on
Have vehicle scanned to determine the problem
Not a problem unless you plan on running the engine... Of course it is a problem. An oil filter is mandatory for the life of the engine.
clicking noise when trying to sart engine usually indicates a flat battery.if the battery is not the problem ,the starter motor needs repair.
