I have a 2004 Nissan Sentra. No heat comes out of the vents and every time I take a right turn or go around a wide right curve on the highway my heat gauge flies up and pins on H. When I straighten out the gauge comes back down to normal. I have had the water pump, two belts and the thermostat which all needed to be changed anyway, and the radiator has been flushed out and it still does the same thing. Please help. I’m at a loss as to how to proceed.
I think you have air in your cooling system. This would explain the “no heat” condition and the fact that the engine overheats when you take a wide turn. The inertia caused by the turn is pulling the coolant away from your water pump which in turn quickly overheats the engine. You need to have the cooling system evacuated of “all” the air by a qualified mechanic. This is a fairly common problem.
There is obviously something wrong with the gauge or sending units.
Take it back to who did he work to make sure all they did was done correctly, and there is no air caught in the system.
Yu may also need to take this to the dealer or a good auto electric shop for the instrumentation checkout.
Who did the cooling system work for you?
Benny’s Automotive on North Main Street in Providence, RI. I think there’s air in the system. The intake hose that runs into the car’s heating system is hot, but the return is cold and seems to have little or no pressure. And the sometimes they’re both cold to the touch.
Right; the top hose is supposed to be HOT and the bottom hose warm, and you should not be able to sqeeze them much with you fingers. It could be that they just added the antifreeze but forgot to add the water to dilute it.
But get it done right away before your engine is damaged.
sometimes a brand new thermostat will stick just as bad as an old one, particularly if some sealant got on it when it was installed,and block the circulation of coolant even if there is adequate coolant in the system. Squeeze the top hose, and you can tell if there is air or coolant in it, by the feel and the sound of sloshing fluid or its lack.
