How to remove heater hoses 1996 blazer


Take off the radiator cap, open the radiator drain **** and close it when it's empty. Remove your hose clamps and CAREFULLY twist the hoses to crack the seal. You may need to use a hose removal tool, depending on how long they've been clamped on. When you're all done, refill the radiator with 50/50 mix of coolant/distilled water, fill the reservoir to the mark and run the truck with full heat on to help bleed the air out of your system. Turn off the engine and let it cool about 1-2 hours. Check the coolant level in the radiator and resevoir and top it off if necessary.

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.

Where is the thermstat at in a 1998 ford taurus?


I'm guessing you can't find it because it's in a separate housing or located under the lower battery tray in the housing (depending on model of engine). Even though this is specific for 1998; I believe it's the same for 1996-1999 Taurus's. I have access to illustrations, but only .gif and/or .bmp extensions were available which would not copy here. If you need these, I will try an extension change to .jpg. Good luck, this should be enough info. It is helpful to include the engine size in question, for future reference...

If mixing occurs, drain engine cooling system and refill with originally equipped coolant type. If this contamination occurs the service change interval on Extended Life Coolant will be reduced from 6 years/150,000 miles to 3 years/30,000 miles.
1.c:\users\bob\appdata\local\temp\msohtmlclip1\01\clip_image001.gif WARNING: NEVER REMOVE THE PRESSURE RELIEF CAP UNDER ANY CONDITIONS WHILE THE ENGINE IS OPERATING. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE COOLING SYSTEM OR ENGINE AND/OR PERSONAL INJURY. TO AVOID HAVING SCALDING HOT COOLANT OR STEAM BLOW OUT OF THE COOLING SYSTEM OR DEGAS BOTTLE, USE EXTREME CARE WHEN REMOVING THE PRESSURE RELIEF CAP FROM A HOT COOLING SYSTEM OR DEGAS BOTTLE. WAIT UNTIL THE ENGINE HAS COOLED, THEN WRAP A THICK CLOTH AROUND THE PRESSURE RELIEF CAP AND TURN IT SLOWLY UNTIL PRESSURE BEGINS TO RELEASE. STEP BACK WHILE THE PRESSURE IS RELEASED FROM THE COOLING SYSTEM. WHEN CERTAIN ALL PRESSURE HAS BEEN RELEASED, PRESS DOWN ON THE PRESSURE CAP (STILL WITH A CLOTH), TURN AND REMOVE PRESSURE RELIEF CAP

Heater problems fan is ok


Have you checked the coolant level? If it is low use 50/50 mix when engine is coo to fill it. If it is low check for radiator leaks, and the hoses going to and from the radiator for leaks. If the coolant is fine then your thermostat/sensor is probably bad. This controls the flow of warm fluid for the heating system.

1993 jeep grand cherokee havc code 06


Chrysler & Jeep Cooling System & HVAC Service: Every car make has its quirks, and Chrysler and Jeep vehicles are no exception. In researching this article, we found several examples of heater problems in these vehicles that seem to be fairly common.

On 2001 and 2002 Sebring Sedan, Sebring Convertible and Stratus Sedan, plus 1993 to 2002 Chrysler Concorde, LHS, New Yorker and 300M, Eagle Vision and Dodge Intrepid models with V6 engines, customers may complain their engine is overheating, or the heater is putting out little or no heat.

Chrysler Technical Service Bulletin 07-002-02 says the problem can be caused by a low coolant level in the cooling system. On these vehicles, air trapped inside the cooling system can displace coolant when the system is refilled. The radiator and coolant reservoir may appear to be full, but there still may be air inside the heater core and heater hoses. This will create a low coolant level that may lead to overheating and low heater output. The bulletin provides a special fill procedure to eliminate the trapped air so the cooling system can be completely filled.

The procedure goes as follows:
1. Obtain Chrysler special tool 8195 (Cooling System Filling Aid). The tool looks like a funnel and attaches onto the filler neck (just as a regular pressure cap does). But it also has a hose clip.
2. Attach the filling aid tool to the cooling system filler neck. Use the clip to pinch off the overflow hose attached to the fill neck. Attach a 4-6' long 1/4" ID clear hose to the bleed valve. Put the end of the hose into a clean container (to prevent coolant from spilling onto the accessory drive belts).
3. Open the cooling system air bleed valve before any coolant is added. If you do not do this, air can remain trapped inside the system and you won't get all the air out. On 1998 and later models with 2.7L engine, the valve is located on the water outlet connector at the front of the engine. On 3.2L and 3.5L engines, the valve is located on the lower intake manifold, left of center under the upper intake manifold. On 1993-'97 models with 3.3L and 3.5L engines, the valve is on the thermostat housing.
4. Pour a 50/50 mixture of coolant and water into the large side of the filling aid funnel. Use distilled, deionized or reverse-osmosis purified water, not ordinary tap water, which may contain salt or minerals that could contaminate the coolant.
5. Slowly fill the cooling system through the large side of the filling aid. Watch the hose connected to the bleed valve. When a steady stream of coolant comes out of the hose, close the bleed valve and continue filling to the top of the filling aid.
6. On 1993-'97 models, place a small, clean container below the end of the overflow hose. Then remove the clip from the overflow hose. Any excess coolant in the filling aid will now drain into the overflow section of the coolant bottle or into the container.
7. On 1993-'97 models, remove the reservoir and recycle the excess coolant.
8. Remove the filling aid from the fill neck. Make sure the filler neck and cap are clean, then replace the pressure cap on the coolant bottle.

Note: 1998 and later coolant bottles have two chambers. Coolant will normally only be in the inboard (smaller) of the two. The outboard chamber is only to recover coolant in the event of an overheat and should normally be empty - except for the coolant drained from the filling aid. This coolant will be drawn back into the pressurized side of the cooling system over time.

Hope helps.

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

    I Suspect that you have AIR in your COOLING SYSTEM Fallow Procedures BELOW to Insure there is NO AIR IN COOLING SYSTEM


    Draining and Filling Cooling System

    Draining Procedure

    Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240,000 km, (150,000 mi) , whichever occurs first.

    1. Park the vehicle on a level surface.
    2. Remove and clean the coolant recovery reservoir.
    Caution: Refer to Radiator Cap Removal Caution in Service Precautions.

    1. Remove the radiator cap when the engine is cool:
    3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap.
    Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound.

    1. Place a drain pan under the radiator drain valve in order to collect all of the used coolant.
    2. Open the radiator drain valve located at the bottom of the radiator tank. If only partial cooling system draining is required, drain enough coolant to perform the procedure.
    3. Open the air bleed valve on the thermostat housing 2 full turns
      1. Open the air bleed valve above coolant pump 2 full turns.
      2. Place a drain pan under the engine block drains in order to collect the used coolant.Important: Allow the coolant to drain completely.

        1. Remove both of the engine block drains.
          • The front left engine block drain is located between the starter motor and the engine oil filter.
          • The rear right engine block drain is located near the crankshaft position sensor.
        Filling Procedure
        Reinstall the engine block drains
      3. Close the radiator drain valve,
        1. Install the coolant recovery reservoir. Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL coolant. If Coolant other than DEX-COOL or HAVOLINE DEX-COOL is added to the system the engine coolant will require change sooner; at 50,000 km (30,000 mi) or 24 months.
        2. Slowly add a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water to the radiator until the coolant level is at the base of the radiator fill neck.
        3. Wait for 2 minutes and reinspect the level of the coolant in the radiator. If necessary, add coolant to the radiator until the coolant level is at the base of the radiator fill neck.
        4. Install the radiator cap.Ensure that the radiator cap arrow points toward the radiator overflow tubeImportant: The air bleed valves are brass. Do NOT over-tighten the air bleed valves.

          1. Close the air bleed valve above the coolant pump.
            1. Close the air bleed valve on the thermostat housing.
            2. Fill the coolant reservoir with a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water. Caution: Refer to Radiator Cap Removal Caution in Service Precautions. Important: If the coolant temperature indicator turns ON, turn the engine OFF immediately and allow the engine to cool. Do NOT remove the radiator cap.
            3. Start the engine and allow the engine cooling fan to cycle on and off 3 times. If the low coolant indicator does not turn OFF and the coolant level is above the Full Cold mark on the coolant recovery reservoir, refer to Engine Coolant Temperature Gage Inaccurate or Inoperative.
            4. Turn off the ignition.
            5. Allow the engine to cool.
            6. Ensure that the engine coolant concentration is sufficient.
