Question From suzanner on HELP!1998 oldsmobile aurora overheating

Help please car is overheating. Done all compression tests, new water pump, new raditor, thermostat was rusted solid removed and did not put new one in--thinking it would help to keep the engine cool. Could not replacing the thermostat cause it to overheat? Or any other suggestions? Thanks suzy. Personal contact info removed.

Response From Hammer Time

There are dozens of reasons for overheating, depending on the condition of the cooling system and yes, it does require a thermostat at all times.

Response From Discretesignals

thermostat was rusted solid

That's not a good thing. You flush the engine and coolant system out before replacing the radiator?

Does it overheat sitting at a light or while cruising?

Response From suzanner

Thanks for the feedback. Car didn't run for a year. It overheats while sitting.

Response From Discretesignals Top Rated Answer

Do the electrical cooling fans come on when it is getting hot? If you have the ac turned on, do the fans come on?

Response From suzanner

When it reaches 190-200 low coolant light clicks on as well as fans.

Response From Discretesignals

Did you flush out the system really well, including the heater core?

Response From suzanner

Yes I did n still overheating.

Response From Discretesignals

When the fans come on, is the air blowing out of the fans hot? Feel the heater hoses. Are they hot?

Response From suzanner

Heater hose is hot and building pressure. Fans are blowing cold. If there is any trapped air in the system will that cause it to overheat.

Response From Discretesignals

Makes us wonder why it was sitting so long.

Yes, that will definitely cause it to overheat. If there is combustion gases getting into the coolant system, no amount of bleeding is going to work. A cylinder leak down test can reveal if there is a head gasket problem, cracked head, or cracked cylinder wall. You'll see bubbles in the coolant system when you pressures the cylinder. Compression tests may not give you an indication if the leak is small.



Some of techs use vacuum coolant lift system to do refills on those, because they do like to trap air sometimes.

Here is the service procedure:

FILLING PROCEDURE

1. Close the radiator drain cock.

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

NOTICE: Do not use a solution stronger than 70% antifreeze. Pure antifreeze can freeze at -22°C (-8°F).

NOTICE: This engine uses DEX-COOLS and GM coolant supplement (sealant) P/N 3634621 specifically designed for use in aluminum engines. Failure to use the engine coolant supplement (sealant) and the approved coolant antifreeze could result in major engine damage.

When refilling the cooling system, add three pellets of the engine coolant supplement sealant GM P/N 3634621 to lower the radiator hose.

2. Refill the cooling system. In order to ensure sufficient Cooling System, freezing and corrosion protection, maintain the coolant protection level at -37°C (-34°F) or lower.

3. Set the heater and A/C control in any A/C mode except MAX. Set the temperature to the highest setting.

4. Allow the engine to continue idling until the lower radiator to coolant pump hose becomes hot.

5. Cycle the engine speed up to about 3,000 RPM and back to idle 5 times. On the VIN 1 engines, slowly open the bleed valve on the rear of the thermostat housing for about 15 seconds in order to release any trapped air in the cooling system.

6. After the air has been released, fill the radiator. Install the radiator pressure cap/surge tank. The arrows on the radiator pressure cap must line up with the coolant recovery tube.

7. Allow the engine to cool to the outside temperature. Check the coolant level. If the coolant level is not at the Add (of Full Cold) mark, add coolant until the coolant reaches the mark.

Response From suzanner

If there's 210 lbs pressure per cylinder and they all hold steady with no leaks will that void out a head gasket. It has good compression in all cylinders.

Response From Discretesignals

The static compression pressure in the cylinders doesn't hold because the pressure will bleed off through the rings. An engine's cylinder isn't perfectly sealed. The reason the pressure stays where it is on your gauge is because it has a check valve in it. This means you could have great compression, but still could be getting gasses into the coolant system.

A leak down test actually pressurizes the cylinders with compressed air. The tester tells you the leak down rate of the cylinder. Since it is using compressed air, it keeps the cylinder pressurized and any leaks going into the coolant system will show up as bubbling in the reservoir.

Response From suzanner

Heater hose is hot and building pressure
