Question about 1993 Chevrolet Lumina

1 Answer

I have a 1993 Chevy Lumina 3.1 v6. The low coolant light stays on even when the coolant is full. I bled the system and changed the thermostat and still doesnt go off. I have also noticed that if i go on trips and try to check the radiator, the coolant doesnt spew out like it should. Do u know what would cause this and what I could do to fix it?

Its not the expansion tank you need to look at. Open the radiator cap when the engine is cold. Coolant should be right at the top. Was all the air bled from the system when these components were replaced? If the system has air in it, it will not effectively cool. Was the thermostat installed correctly? ( Put in backwards ). Electric rad fan? Is it operational?

Why is my1997 chevy lumina low coolant light is on and the radiator is full of coolant ?

In most newer chevys, the coolant reservoir is part of the pressurized system. Rather than just holding overflow coolant and relying on the radiator pressure cap to draw from and expel to the reservoir, it is an active part of the cooling system. On these systems, there is a coolant level switch in the reservoir. This will activate if the level in the reservoir gets below a certain point. So it is possible to have a full radiator and still get a low coolant light. Be advised that as the reservoir ages and get stained, it is not uncommon for the low coolant sensor to give false indications of low coolant.

1998 Chevy Lumina 3.1 overheating - top radiator hose collapses on throttle, then opens up when you let off.

With the engine cold remove the radiator cap. Start the engine. Watch the coolant. If you see bubbles constantly perkulating out of the coolant than you most likely have a head gasket that has failed. If you don't see a constant perkulation of air bubbles it probably wouldn't hurt to replace the upper hose and see if the problem is resolved.

I have a 4-door 1992 Chevy Lumina Euro 3.1L V6... what does it mean when you're low coolant light is on and your temp light starts to cut .. and my car is start to stop when i come to a complete stop...

You need to repair the low coolant condition before any more diagnosis. If the coolant in the radiator is low that's what the light is telling you. You may have a coolant leak. fix that first then make sure the cooling system is full. Use coolant (50/50) not water.

I've been having some problems with my Low Coolant Light flashing off and on,and after I get home and wait for my radiator and engine to cool down,I check my radiator and it's full of coolant! Is a...

Coolant level sensor failures are common. It is located in the radiator tank on the right (passeger) side of the radiator. it looks like the picture below. Also, there has been a lot of problems with the connector for these sensors. (see picture) AutoZone stocks BOTH of these parts. Inspect the connector for breakage, corrosion and insulation peeling off of the wires. If there are no problems found with the connector, then you can probably just replace the sensor.

After I added coolant to 91 chevy lumina the low coolant light will not go of I wonder why

When filling the coolant system you need to have the car running with radiator cap off and you can also burp the coolant hose while filling the system to remove any air. The system may be full for a while until thermostat opens and sucks the coolant out of radiator which is the perfect time to add more to top it off.

Disconnecting your negative battery cable for 10 minutes will reset the computer and shut off the light.

1995 chevy lumina minivan radiator leak while running?

A radiator cap with a bad seal will allow the coolant bottle to stay full but the rest of the coolant system to get low. Water pumps on the V6 engines will leak only when the engine is running. But you will find coolant on the right side of the car. If you do not see coolant on the ground where you park it could be the intake manifold gaskets leaking. This has been a big problem for GM, run a Google search. You can take it to a service center and they can test the system and tell you where the coolant is going.
