My coolant light comes on and goes off intermittently. reservoir level is where it should be. How do i have to add more to rediator as the manual says? or could it be water pump?

 

Could this be a minor radiator leak? How old is the radiator?

 

Are you saying that the water level in the radiator is going down, but the water level in the reservoir is not? If so, then make sure that the hose that joins the two is not loose or leaking. It needs a tight seal in order to siphon water into the radiator as it cools down.

If that hose is good, then replace the radiator cap.

Good luck.
