SOURCE: my volvo 850 gets hot but the indicator of

The radiator signal lamp is on because the coolant level is low (there is a leak somewhere). The temp indicator doesn't show hot because the sensor probably has no coolant flowing past it to sense the temperature. This should be repaired as soon as possible before the head gasket needs to be replaced.

My car is Audi A4 1999 model.It comes with an auto

Min is the minimum amount needed in the reservoir to correctly operate the radiator . You should be filling to maximum as the difference between the two levels is what the radiator normally works with. . water level should be checked at the radiator cap as it is very possible to have a full reservoir but have an empty radiator. As long as the water level stays between the level marks then it is not necessary to top up the reservoir every day. If there is a drastic drop in the level or there is no change then I suggest checking the radiator cap once a week

My 2003 Nissan Sentra has been experiencing overheating problems for almost a year now. I have Changed the Thermostat 3 times and the radiator and the water pump and the hoses. I also changed the cool

I am right now experiencing and dealing with the same problem. My car is a 2005 Nissan Sentra 1.8. I first changed the thermostat, but that is not necessary in many cases.
Remove the radiator cap and wrap a paper clip around the center of it, just under where the flat piece of metal retains the rubber seal. (See image below.) This will allow water and air to escape the radiator and go into the reservoir. Put a hydraulic jack under the front of your car in the center (there is a factory 'nipple' there for just this use). Jack the front of your car up until the front tires just leave the ground (best done on hard, flat surface). This will allow air to travel up the motor & head, out through the hose and exit the top of the radiator and into the reservoir. Be sure the radiator is full of anti-freeze/coolant. NOT just water, because you will have to go through all this again before winter. Place the 'altered' cap on the radiator and start the car. Let the car run until the temp comes up to normal operating temperature. The coolant should now fill the reservoir. Now, turn the car off and do nothing else, for now. Wait until the motor is cool and the coolant in the reservoir should go back into the radiator. DO NOT allow the reservoir to get empty, or air will enter again and you will have to repeat all this again! If you keep enough coolant in the reservoir tank, the cooling motor will draw pure coolant/anti-freeze back, leaving the air out. When the motor is cool, be sure the coolant level in the reservoir is at the "Cold" or "Min" mark. Start the car again and watch the reservoir through the filler hole. You should begin to see air bubbles exiting into the tank. This is GOOD! Allow the motor to run at idle until you see no more air bubbles (probably 10 minutes or more). Add coolant as necessary as the level will probably drop a little as the engine's fan comes on, causing negative pressure in the motor/radiator. Make sure the reservoir coolant tank level is at "Hot" or Max" and turn the motor off again. After repeating this process two or three times, the heater will probably put out a "little" heat, but not a lot. If the heater begins producing max heat, your job is probably done. With the paper clip still in the radiator cap, put it out on the road, where you can get it up to speed (55 - 65 mph) and watch your temp gauge. At some point, the temp should drop down to normal and the heater work good again. The key is getting ALL the air out of the motor and head, without drawing the air back inside.
When everything is good (hopefully running cool and heater working), allow the motor to cool down (COLD) and remove the paper clip from the radiator cap.
Do this ONLY when the motor is COLD, or you could create another air pocket. Do not add coolant/anti-freeze to the radiator at this time (REALLY!). Just replace the cap and add fluid to the reservoir, if needed.

I hope this helps you.

My Dodge Stratus 2005 is leaking coolant. No trace to be found. I discovered last week that the whole coolant reservoir was empty. Yet the car's temperature was at normal level. There are no trace

Look in the radiator in the morning when car is cold take off the cap if it is full then look at the reservoir and make sure you see to lines on it one you fill to when cols the other you fill to when how it will say hot and cold fill lines fill yo cold when it is cold then next day check and see when cold if it is at the same mark

The radiator was emptied out and i want to add antifreeze and water? there are 2 areas that say antifreeze goes here?

  • One is the radiator and the other is an overflow tank. Sometimes anti freeze will back pressure a bit and need somewhere to go and other times the antifreeze gets low in the radiator. That is the purpose of the radiator.
  • Put the antifreeze in the radiator fist and then add to the reservoir. Pay attention to the cold/hot level fill on the overfill tank.
  • You need to find out where all that antifreeze went to if the radiator was empth. Pull the dipstick and look for a chocolate milk look on the oil. This would be a head gasket or a cracked head.
  • Otherwise keep an eye out for a leak and repair it soon.
  • Hope this helps and thank you for using FixYa.

Does the 1997 honda civic have an air lock preventor Every morning I have to throw the built up coolant back into the radiator from the auxiliary container. When I open the radiator, the air belches...

The only thing I can think of that would cause this is if the antifreeze is old or weak or diluted down with too much water. Try the following:prev.gif next.gif DRAIN & REFILL Fig. 1: Remove and drain the reservoir recovery tank 91161p06.gif
Fig. 2: Location of the radiator draincock 91163p27.gif
Fig. 3: Use your hand to unscrew the plastic draincock 91163p28.gif
Fig. 4: To refill the recovery tank, twist the cap . . . 91161p09.gif
Fig. 5: . . . then pull up to remove it from the tank 91161p10.gif
Fig. 6: Adding coolant to the reservoir bottle 91161p30.gif
Fig. 7: Always check the condition of the radiator cap gasket and seal. Place a light coating of coolant on the seal and gasket when installing tccs1079.gif
When draining the coolant, keep in mind that small animals and domestic pets are attracted by ethylene glycol antifreeze and may attempt to drink any that is left in an uncovered container or from puddles on the ground. This can be fatal if ingested in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused until it becomes contaminated or several years old. To avoid injuries from scalding fluid and steam, DO NOT remove the radiator cap while the engine is running or if the engine or radiator is still hot.
  1. Before draining the cooling system, place the heater's temperature selector to the full WARM position while the engine is running.
  2. Turn the engine off before it gets hot and the system builds pressure.
  3. Make sure the engine is still cool and the vehicle is parked on a level surface.
  4. Remove and drain the reservoir recovery tank.
  5. Place a fluid catch pan under the radiator. Turn the radiator draincock counterclockwise to open, then allow the coolant to drain.
  6. Remove the radiator cap by performing the following:
    1. Slowly rotate the cap counterclockwise to the detent.
    2. If any residual pressure is present, WAIT until the hissing stops.
    3. After the hissing noise has ceased, press down on the cap and continue rotating it counterclockwise to remove it.
  7. Allow the coolant to drain completely from the vehicle.
  8. Close the radiator draincock. NOTE: When filling the cooling system, be careful not to spill any coolant on the drive belts or alternator. To refill:
  9. Make sure the heater temperature is placed in the full hot position.
  10. Open the bleed screw on the thermostat housing.
  11. Install the reservoir recovery tank and using a 50/50 mixture of the recommended antifreeze and clean water, fill the cooling system reservoir tank to the FULL mark. WARNING
    If any coolant is spilled on a painted surface, wipe it up immediately.
  12. Begin filling the radiator with the 50/50 mixture of coolant. Watch for air being released from the open the bleed screw on the thermostat housing. Once coolant mixture begins to steadily flow through the bleeder, close the bleeder.
  13. Continue to fill the radiator until the radiator is full.
  14. Start the engine and allow the engine to run until the cooling fans operate two times, making sure to top off the system as the fluid level drops.
  15. After the cooling fan has run for the second time, top off the system as necessary, then install the radiator cap.
  16. Allow the engine to run and inspect the cooling system for leaks.

Do i need to add coolant to my reservoir if it is empty, 97 chevy suburban

Yes. Before you do, remove cap on rad when engine is cool & top it up too, if needed. Keep an eye on temperature gauge for a day or 2 & coolant bottle level, just in case there is another problem.
