2006 jeep grand Cherokee limited if the radiator overflow jug is empty will it cause the transmission temp light to come on


I would say it is possible an overheated engine which is not coolling the transmission can trigger a lot of lights. Many transmissons are heated and coolled by a line which goes to the radiator of the engine cooling system.

How do you bleed the air from the cooling system of a 1999 v6 pontiac grand am


Refilling Procedure




Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL?"¢ coolant. If coolant other than DEX-COOL?"¢ is added to the system, the engine coolant will require change sooner: at 50 000 km (30,000 miles) or 24 months.






  1. Close the radiator drain cock.


  2. If previously removed, install the engine block drain plugs.


  3. When installing the drain plugs, use pipe sealer GM P/N 12346004.




    Important: On vehicles equipped with the 3.4L engine, open the coolant air bleed valve. The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.



  4. Fill the surge tank to the base of the filler neck.


  5. Start the engine with the pressure cap off. Run the engine until the upper radiator hose starts to get hot.


  6. If the coolant level in the surge tank is low, add the proper mix of coolant until the level reaches the full cold line.



  7. Important: After servicing the cooling system, and if the vehicle is equipped with an intermittent low coolant light, an occasional low coolant light may be encountered during some extreme driving maneuvers. This complaint should be eliminated by removing the surge tank cap and adding coolant to a level just at or above the full cold line when the system is cold.



  8. Install the cap onto the tank with hand tight pressure.



Recycling Procedure




Important: Dispose of used coolant in a proper fashion, such as in a used coolant holding tank. Never pour used coolant down the drain. Ethylene glycol antifreeze is a very toxic chemical. Disposing of ethylene glycol antifreeze into the sewer system is both illegal and ecologically unsound.



There is currently no approved method for recycling used DEX-COOL?"¢ coolant into new DEX-COOL?"¢ coolant. DEX-COOL?"¢ coolant can be recycled into new conventional coolant. Consult local listings for coolant recycling facilities in your area.

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.

'low coolant light' flashes all the time and then 'service engine soon'


These problems may or may not be related. The Check coolant light means that the coolant level in your radiator is low. If you have checked it and it is not low, then the sensor is most likely defective. The low coolant sensor will not turn the Check Engine light on - even if the coolant really is low. There are many things that can cause the Check Engine light to come on. You will have to scan your Engine Computer to find out why it has been turning the light on.

I did have a problem on one of these cars one time where the Check Engine light was coming on and there were several codes for the Throttle Position Sensor(TPS) and the Manifold Absolute Pressure (MAP) sensor and the car ran really bad. The Check Coolant light was also on. After checking it out I found that the coolant level sensor was shorting out the 5 volt reference circuit (VREF) from the computer and causing the whole problem. Replacing the coolant level sensor fixed the car.

COOLANT-ADDING ADDITIONAL
Do not remove radiator cap to add coolant to system. When adding coolant to maintain correct level, do so at coolant reserve/overflow tank. Use a 50/50 mixture of ethylene glycol antifreeze containing Alugard 340-2 y and low mineral content water.
Remove radiator cap only for testing or when refilling system after service. Removing cap unnecessarily can cause loss of coolant and allow air to enter system, which produces corrosion.

COOLANT LEVEL CHECK
The cooling system is closed and designed to maintain coolant level to top of radiator.
WARNING: DO NOT OPEN RADIATOR DRAINCOCK WITH ENGINE RUNNING OR WHILE ENGINE IS HOT AND COOLING SYSTEM IS UNDER PRESSURE.
Remove radiator cap. The coolant level should be to top of radiator. If not, and if coolant level in coolant recovery bottle is at ADD mark, check for:
  • An air leak in coolant reserve/overflow tank or its hose
  • An air leak in radiator filler neck
  • Leak in pressure cap seal to radiator filler neck

Service engine soon light came on what could it be. Car still runs good. only 65,000 miles on the car.


Check the coolant resevoir. When the coolant level gets low, that will trigger the check engine sensor to come on. If the level is low, just add a little anti-freeze/water mix too it.

Is there special directions to put coolant in?


Welcome to FIxYa.com



How to Fill Coolant

If the coolant system has been flushed, first add 100 percent ethylene glycol in

the amount listed for the appropriate engine application. Then slowly add clean

water to the system until the level of the coolant mixture has reached the base-of

the radiator neck. Wait for two minutes and recheck the level of the coolant

mixture. add clean water if necessary to restore the coolant mixture level to the

base of the radiator neck

When refilling the engine cooling system, add three engine coolant supplement

sealant pellets, GM RN 3634621 or equivalent, and GM approved new Ethylene

Glycol Coolant DEX-COOL GM RN 9985809.

If the cooling system is being refilled ONLY (no flush), a 50 percent ethylene

glycol and 50 percent clean water mixture should be used to fill the system. Fill

the system until the level of the 50150 mixture has reached the base of the radiator

neck. Wait two minutes and recheck the level of the coolant mixture. add a 50/50

ethylene glycol water mixture as necessary to restore the coolant mixture level to

the base of the radiator neck.

Install the radiator cap making certain the arrows line up with the overflow tube.

Close all air bleeds. DO NOT over torque the air bleed valve. The air bleed valve is

made out of brass.

Fill the coolant reservoir with a 50 percent ethylene glycol and a 50 percent clean

water coolant mixture. The proper amount of this mixture to be installed into the

coolant reservoir is listed below:

Add 0.65 liters (0.68 quarts) of a 5010 mixture of ethylene glycol and clean water

to the coolant recovery reservoir.

CAUTION: The low coolant indicator lamp may come on after this procedure. After

operating the vehicle so that the engine heats up and cools down three times. if at

any time the "TEMP' warning indicator comes on. Immediate action is required.

Air bleed vent is at the thermostat house

When i first start the car a message appears that says ENGINE COOLANT LOW. CHECK SOON. When you check the coolant(AFTER IT HAS COOLED) , it shows to be exactly where it is suspose to be. 1999 bUICK...


The low coolant switch may be stuck, and you may even have to replace it. Last time I replaced one it was in the radiator. Also make sure the level is good in the radiator when cool.
