1. Improper water circulation: Sometimes, eventhough you are sure that you have enough water on your radiator, your car still overheats. It might probably be that the water is cannot circulate properly, which results to improper cooling process. There are several reasons for this which you can discover by yourself. To verify if the water circulates properly, start your engine without the radiator cap. If water circulation is good, you should notice that the water pops smoothly over the top but still retains the amount. Another way to check, detach one of the ends of your radiator hose from your radiator and see if water flows continously over.
If water doesn’t circulates well, check the thermostat if it’s open. It should be open, meaning clean, and the water can pass through it.
If thermostat is clean and still the water doesn’t circulate properly, then you have to check the water pump. That’s probably where the problem is. A little leak on the pump will cause improper flow of water through the radiator system.
If you are sure that the problem is not about water circulation, another thing you can consider is check the engine oil. Very low amount of oil can cause greater friction of the mechanical system of your engine. If it’s not time to change oil yet, you can add over some amount of oil until advisable amount is reached.
While we can’t be always sure about our engine, especially if it’s not new, we should be prepared when it happens. Bringing extra gallon of water in your trunk will surely help.

Nissan Altima running hot


You may have to replace your thermostat. If the thermostat is not working properly, you will have over heat. You make also have a bad thermostat gasket and that's where the water leak from. It might be leaking a little at a time and the engine is hot so its dry before you can see it.

No heat ..help installed new heater switch, replaced water pump..replaced coolants, and thermostat......................what else could it be? Nissan 2003 GXE Sentra 1.8 L Engine/...


you could have an air pocket in the cooling system that has to be burped. With a cold engine, park uphill and leave the radiator cap loose. Fill radiator and coolant reservoir. Start engine with cap loose and run at 1500 rpm until temp gauge reads normal. Feel if top radiator return hose from engine to radiator is hot. If yes, coolant is flowing and thermostat is open. If cold, thermostat is not staying closed until engine is hot.

report results.

I have a 94 nissan altima that overheats. I


sounds like where the water pump meets the engine has warped or the gasket has been blown. Since the water pump has to come out anyway to fix it then i would suggest replacing the pump. It is 30 to 40 more.

1998 altima overheating


It may be the thermostat, but you should also check:-
1) Coolant level is at correct level (full) when checked cold- prior to running,
2) Cooling fan/s are running normally as they should when coolant temp rises,
3) A coolant hose on the suction side of the water pump is not collapsing (due softening) causing restricted coolant flow,
4) Radiator coolant core is not blocked, or radiator heat dispersion air fins blocked with insects/grass,
5) Engine does not have other running problems that cause it to overheat.

How many termostats does a 2003 nissan altima have and how easy to fix.


There is one thermostat for coolant and it is located at the end of top radiator hose inside the kneck that it connects to. To replace this the hose has to be removed and then the kneck,thermostat is brass colored valve that covers center of hole,clean old gasket from block side and kneck replace with new one and gasket with a bit of rtv sealant tighten kneck evenly when putting it back on,connect hose wait a short while for rtv to set up and should be good to go,"make sure engine is full of coolant b4 reassembling,just pour strait in engine if it isn't or you can damage new thermostat.overheating can also be sign of water pump not working as well so if still having problem then it is possible cause and on older models radiators get clogged.

Heater blowing cold air


My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
