SOURCE: Radiator cooling fan doesn't come on.

first unplug the cooling fan at its plug and supply 12v to the fan if it doesnt run then replace if it does run follow the power wire to the thermal water switch usualy located at the bottom of the radiator.Use test light/probe to check that you have power into the switch and when engine is hot you should have power both in and out of the switch.if not replace thermal water switch.If that is working you will need to find out why you have no power to the switch.Check that your fuse and relay is working correctly.Sometimes just pulling out the relay and putting back in will make it work due to poor contact.Also try swapping relays with others in the same box near battery to identify if relay is faulty

SOURCE: Radiator Fan's Run All The Time

There are 2 things that will cause this to happen. 1. The thermostat needs to be replaced and, 2. The coolant sensor can be bad. When I had this problem, I changed them both at the same time, she been just fine since then. Also, I had the check engine light on, and got the code from AutoZone (it's free!)

SOURCE: The radiator cooling fan is not working. Upon

assuming fuse and relay are good..no fan should be running when the engine is cool/cold, the only time the fan should be running when it reach over operation temperature which then the fan kick on to bring the temperature back down to it operation temperature. both fan work in sync with one another, addition cooling is needed when the ac is running. when the last time have you replace thermostat and Thermos sensor/switch. I would replace both unit if you have not done so. The thermos/switch will turn the fan on when it reach certain temperature and cut off when it sense the temperature drop in the engine.

Will an air pocket in the coolant system cause it to overheat or over pressurize on a 2001 Nissan Sentra ?


1. The radiator cap if working correctly it will release pressure in the system provided the cap you have is the correct pressure setting. If you are having a problem with pressure then replace the cap with a new radiator cap with the correct pressure setting. Do not use a cap with a pressure setting other than the original equipment pressure spec. So you do not go to the parts store and buy any radiator cap on the shelf that fits because they come with different pressure ratings and some of these will be totally unsuitable for your car.

2. If the pressure valve is stuck in the "old" cap the pressure release system will not work.

3. Overheating
Air pockets in the cooling system can definitely cause overheating and can retard coolant flow through the system. If you are draining the radiator to replace the coolant or replacing the radiator you need to follow the correct procedures for bleeding air out of the system for that particular engine after coolant refilling. Some engines have bleeder screws on the cooling system to assist in the air bleeding procedure and some don't.

There are various causes for overheating so don't assume it will necessarily be solved by bleeding any remaining air from the cooling system and replacing the radiator cap with one that works.

Other causes can be...........
1. Faulty cooling system thermostat. (Replace the Thermostat)
2. Faulty water pump, especially if the impellers have corroded away or have disintegrated in the case of those design genius water pumps with plastic impellers. (Replace the water pump)

3. Cooling fans not working and if so the cause needs to be tracked. Check that your fans are kicking in. If the engine is overheating the fans should be running because they will switch on when the coolant reaches a specific temp and well before the coolant gets excessively hot.

4. A partial blockage in the coolant passages inside the engine but not in the radiator if you have a new one. If the coolant is not changed at the required intervals(frequently the case with many owners) or is over diluted with water you can get a build up of debris. If products like stop leak have been used in the system this can create similar problems with partial blockages inside the engine coolant passages.

5. A compression leak into the cooling system.
If you have bled air from the system and have continuous air bubbles in the cooling system I would suspect a compression leak. In that event a basic leak down test will show if you have compression gasses leaking into the cooling system and from which cylinder(s). The spark plug is removed and compressed air is forced into the cylinder via the spark plug fitting and air bubbles will show up in the coolant of there is a leak into the cooling system.
--------------------------------
Have the problem with overheating addressed immediately. Running the engine with an overheat condition will cause expensive engine damage many times the cost of fixing the overheating issue.

2007 Nissan pathfinder radiator coolant mixing with transmission fluid


This is a common problem with the radiators in the Pathfinders and Frontiers, Nissan is aware of this and have extended the warranty to 80k miles for this issue. The ATF fluid is cooled in the lower half of the radiator and when the radiator fails the two fluids mix causing failure to the transmisson if not addressed immeadiately. You should bring your vehicle to Nissan and have it looked at ASAP. If caught soon enough you can flush the tranny and replace the radiator and be okay. if not then you are looking at rebuilding/replacing the transmission. Hope this helps

What is the radiator capacity?


Depending on the size of your engine, and if it's 2WD or 4WD, the cooling system can hold from 8-5/8 to 12-3/8 quarts
