first off make sure the car has cooled down from its last drive then remove the radiator cap now look at the bottom of the radiator you should see an odd looking white screw that sticks out remove this screw it is the drain for the coolant make sure you have a bucket to dispose of the coolant once it has drained get your garden hose and flush it out then refill it

f.y.i. coolant is very sweet to the taste but it is very poisonous so make sure you do not leave it out for any cats or dogs because they will drink it and die

You could possibly have air trapped in the heater core. The easiest way to bleed it out is to jack up the front of the car till the radiator fill cap is higher than the upper heater hose using a funnel that fits snuggly in the filler neck of the radiator, fill till you have about three inches of coolant/antifreeze above the filler neckthen run the car at about 1500rpms until no more bubbles are evident. Also turn the heater onto face on low speed and feel if heat starts comming out.

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.

I have a 1998 nissan altima. the engine is a ka24de..5 speed manual transmission.. i have replaced the radiator all radiator hoses the thermostat and the thermostat housing and the freeze plugs. the car...


have you replaced your drive belts?? i have seen a guy install the alternator belt the wrong way on the same model year vehicle and it would overheat in the bay after about 10-15 minutes at idle. the water pump was spinning backwards, not pushing coolant through the engine. its very easy to do that on your car and the belt will actually go on and tighten for you and it will all look ok, but its not.
also there is a bleed screw for the coolin system for you to loosen up before you refill the cooling system. if you drained the coolant to change those things that you changed, did you re-fill it properly?? you may have an air pocket in the system, but that should work its way out after a while, which will lower coolant level in the system, so you have to add coolant to top it off.

How to replace coolant for nissan altima 2006


Park the Nissan Altima on a flat surface and set the parking brake. Next, open the hood and check the external temperature of the radiator. If the radiator is warm to the touch, wait for the radiator to cool before you continue.

Twist the radiator cap one turn to relieve any pressure. Step back from the radiator and allow a few seconds to pass, and then completely remove the radiator cap.

Place a bucket or tray with at least a 2-gallon capacity underneath the radiator and below the drain plug. The drain plug on a Nissan Altima is on the passenger side bottom of the radiator.

Loosen the drain plug and let the old coolant drain completely into the bucket. Take care while loosening the drain plug, because it's plastic and can be brittle. Pour the old coolant into a sealable container for proper disposal later and put the bucket back under the drain plug opening.

Close the drain plug and pour distilled water into the radiator until it's full. Then, open the drain plug and let the water flow into the bucket. Keep repeating this procedure until the water runs clear and debris free into the bucket. You will need at least 3 gallons of distilled water.

Make sure to tighten the drain plug and fill the radiator with fresh coolant. Refill the radiator to within an inch of it overflowing. Check the drain plug and hoses for any possible leaks.

Start the Nissan Altima and turn the heater to the high setting. Let it run for about 10 minutes and shut the engine off. Check the coolant level and refill, if necessary. Finally, put the radiator cap on and close the hood.

How do I replace the thermostat on a 2000 v6 nissan xterra


3.3L Engine

7d00e82.jpg

Fig. Thermostat assembly and related components-3.3L engine

NOTE Never remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator.
  1. Be sure the engine is cold.
  2. Disconnect the negative battery cable.
  3. Drain the coolant. Properly disposed of used coolant.
  4. Remove the upper and lower radiator hoses. Remove the fan shroud.
  5. Remove the drive belts and the pulley bracket.
  6. Remove the water inlet retaining bolts.
  7. Remove the water inlet and the thermostat.

To install:
  1. Installation is the reverse of the removal procedure.
  2. Be sure to apply a continuous bead of the proper grade and type RTV sealant to the housing.
  3. Install the thermostat with the jiggle valve or air bleeder at the upper side.
  4. Be sure to refill the cooling using the proper grade and type engine coolant.
  5. Start the engine and check for leaks.
  6. Start the engine and allow it to reach operation temperature. Recheck the coolant level, fill as required.

Hope helps (remember rated this)

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.

Steam coming from engine


hi,
how far away is the repairman? if its less than 2 miles then go ahead. fill up the coolant reservoir AND the radiator locate the radiator cap and fill it too. I dont recommend doing it if you cant fill up the radiator. go early in the morning before it gets hot. if it starts to boil shut it off at the lights. take extra water with you and a rag or gloves and of course the phone. good luck

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!
