About five days ago, I observe the temprature indicator of my mazda 626 97 model rise to the max 15-20 min having on the Ac.
Even without the AC the temp. indicator is about mid way, it was never like that before now.
Please, what do I check, need your advice.
Thanks

Well, since you say your temp gauge never reached halfway, you are probably without a thermostat or it's stuck open; so we may rule that out for now as a cause. So check your radiator for dirt and rust (and possibly replacement); the radiator cap for wear; and the water pump too for wear.

thanks costee, the thermostart has been removed, the radiator is new and the cover too, I would have mechanic check the water pump, or there a way I could check that myself?
