HELP I AM SINGLE MOM AND HAVE TO GO TO WORK, CAR RUNNING HOT
Just replaced my radiator in my 2000 Nissan Maxima because it had a crack in the top of it and car overheated. Just noticed that car still running hot, absorbing all the coolant and saw the fan is not working. I wonder if it was the fan failure that blew up my radiator? Why didn't the mechanic realize the fan not work? Perhaps the fuse or fan went out after the fact? What are the 1st things I look for when the fan doesn't work like the fuse? Cannot even get the cover off the fuse itself! Should I take pliers to it? Can I tell by looking at the fuse if it's dead? What else should I check if it's not the fuse?

Go to a salvage yard and tell them the size of your engine and you need a coolant fan because the relay is inside the fan but if you are tight for money and someone knows how to do it you can run a wire to the fan and to the ingition switch but the fan will run all the time while the car is running

Take the radiator cap off, top up the radiator and the overflow tank, and run the car until normal operating temperature is reached. Shut off the car and replace the radiator cap. This usually gets all air out of the coolant system. If you have a bleed valve on the thermostat housing, crack that open until coolant runs out, then close.
i believe the question was explained as fans work!! why all the fan inop answers?? anyway...you will need to check the water pump first...if you change it then make sure your cataltic converters are not plugged. from there its ussually a combustion leak from cracked or defective head gaskets due to the mileage. if it stays cool at idle its deff not a cooling fan problem..the fans only are used primary at idle. hope this helps
hot engine usually due to clogged radiator or bad thermostat. Take out the thermostat and make sure it is opening fully in boiling water.
Look inside your radiator for signs of clogging. If yes, professionally flush or replace radiator.
YOU NEED TO CHECK COOLANT LEVEL.AND CHECK THERMOSTAT.WHEN YOU FIRST START YOUR CAR UP IN THE MORNING .WHEN IT GET OPERATING TEMP.RUN ABOUT 5 TO 10 MINUTES.FEEL TOP RADIATOR HOSE AND THE BOTTOM RADIATOR HOSE.IF BOTH HOSES IS HOT THERMOSTAT GOOD.IF TOP HOSE IS NOT HOT BUT THE BOTTOM IS REPLACE THERMOSTAT.THAT CAUSING ENGINE TO GET HOT.IF ALL IS GOOD.CHECK WATER PUMP WEEP HOLE.IF LEAKING REPLACE WATER PUMP.CHECK COOLING FANS.MAKE SURE THEY ARE RUNNING.IF NOT CHECK FUSE AND RELAYS.
Try replaceing the engine fan controller, make sure there are no bugs in the radiator, there is another coolant sensor cost about $22.00 for it the fan control costs $40.00 bucks since you say it's ok when you have AC on my guess is the fan comes on for the ac and keeps it cool. You also may need a new fan motor, non AC side. sometimes the shats slip and the fan slips on the shaft of the motor an causes it not to turn fast enought.
It sounds like the the thermostat that was replaced is probably faulty. This being the cheapest and easiest to do I would start there. I can't reply about the air pockets. I have never heard of that before.
Simple thing to test first would be to pressure check the radiator cap. Next would be to check for combustion gases in the radiator indicating a leaking head gasket. It is an aluminum head and iron block engine and there is a possibility that antifreeze anti corrosionpackage runs out due to over age then fails due to too long in the engine it results in galvanic corrosion at the head gasket-commonly resulting in a failed head gasket. There are other engines that are vastly more prone to this than the maxima engine. If there is a leaking head gasket the gases could rise to the top of the system and block the water flow into the heater. Listen for gurgling sound in the heater.
