Diagram for cooling system bleeder valve 02 deville


There isn't one !
Filling Procedure
Notice: Do not add cold water to the cooling system with the engine at or above operating temperature. Adding cold water causes rapid cooling, resulting in possible engine damage.
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.
Notice: Do not use a solution stronger than 70 percent antifreeze. Pure antifreeze can freeze at -22°C (-8°F).
Important: This engine is not equipped with block drains, 2.5 L (2 qt) of residual coolant remains in the engine block.
Refill the cooling system. In order to ensure sufficient engine cooling, freezing and corrosion protection, maintain the protection level at -37°C (-34°F) or lower.
Start the engine.
Place the heater and A/C control in any A/C mode except Max and the temperature in the highest setting.
Allow the engine to continue idling until the lower radiator to water pump hose is hot.
Turn OFF the engine.
Allow the engine to cool to outside temperature. Ensure the coolant level in the surge tank is at the proper level (1).

99 Cadillac Seville coolant light coming on. No apparent leakage. Adding coolant 2 to 3 times a week with little driving. Sometimes an anti freeze haze appears on inside front windshield .


HAVE YOU CHECKED YOUR COOLANT HOSES? CHECK TO MAKE SURE THERE NOT LOOSE OR CRACKED. ANOTHER THING COULD BE IS YOUR HEATER CORE HOSES COULD BE BAD. ALSO I WOULD CHECK YOUR RADIATOR CAP THE SEAL COULD BE BAD. I HOPE THIS HELPS YOU WITH YOUR TROUBLESHOOTING.

My 2001 cadillac deville has check coolant level


If you added the green anti freeze to you system it will make the check coolent level light come on. Drain the system and use the extended life anti freeze and that will fix the problem.

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

No you need to have the vehicle scanned for the check engine light to see what the code is that has it on. Autozone will do this for free.
