Question about 1995 Chevrolet Lumina

1 Answer

95 Lumina car, 3.1 , poor heat

I changed both head and intake gaskets a few months ago. I`ve also changed the heater core. Both times the system was flushed and filled. Replaced the thermostat first with a Prestone one then an OEM one (thought my problem was the Prestone thermostat). I just can`t seem to get enough heat out of the car. I know it`s winter. Temps here in Canada are -10 to -20 celsius. My Impala is wonderful for heat. Checked for air in the lines. Can`t seem to figure this out. Any ideas??

    I haven`t yet. But, the temp gage moves too and the heat gets warming when sitting. So, I can get a little more heat if I`m sitting. I know...it sounds like air or a thermostat. But this will be the second thermostat in 2 months. I suppose it`s possible, but very unlikely.
    Is there a way to check that switch??

    Thanks for your help,

Did you check the temperature switch to make sure it was actually turning all the way to high or hot and not staying on cold or medium heat? May need a new control inside car dash.

Heater core repeatedly leaks, changed 3 time in past 3 months and still no solution


You should probably pressure test the cooling system and the radiator cap to make sure it's releasing properly at the correct pressure, and to identify where any leak may exist. I would suggest that you bypass the heater core for the test first, then test once it's repaired & reconnected.

I've heard of this before due to a leaking headgasket, or small crack in the head/block as well as a bad radiator cap that won't release at the correct PSI.

Air bubbles in the coolant system causing the car to run hot


If you are seeing air bubbles, then the cooling system still has air pockets in it. Loosen the overflow cap and leave it that way for a few days while you drive.Keep the heater turned on at the max heat level. Roll a window down if necessary. Check and top up the overflow bucket daily and top up as necessary. The bubbles should disappear after a few days, then you can tighten the cap. This should also solve your no heat problem. Once the bubbles are gone you can tighten the cap.

If the problem doesn't fix itself in a week, you should have the car looked at for a possible bad head gasket, which would force air into the cooling system. Hope this helps.

Have you even considered the heater core? Have the heater core checked/replaced. As for the top hose collapsing...that is not good. Have the entire system checked out by a qualified mechanic.

As far as the poor running and hard starting, yes, it could be egr or valves or timing or almost anything. Your heat problem : I suspect the heater core may be air locked. With the engine running, loosen one heater hose with the heat control on hot, and see if you can get any air out of it.
Also, check your water pump. Squeeze your rad hose as tight as you can for a bit. When you release it, you should feel a surge of coolant go through it.
Check your heat control valve to see that it's working.

CHEVI LUMINA 2001 HEATER failing...might have slow dex-cool leak


The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow.

If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm.

If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air.

If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted.

One or a combination of these factors is likely the culprit in your case.

Flush the heater core 2-3 times, and if the obstruction does not clear, a new heater core is required.

However in your case, a cracked head is suspected - this will give out a plume of white smoke on startup - There is no smell, carpet dampness, or abundant moisture in the cabin? (this warns of a leaking heater core)

The coolant is leaking through a gasket or crack, and entering the combustion chamber. You dont see a leak on the ground because it is being burned up with the fuel.

Good Luck, and thanks for using FixYa - A FixYa rating is appreciated!!

if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.

yes I can help! it seem that you have some air in your cooling system. first you will have to drain the system by removing the lower radiator hose. clamp the radiator hose in place refail the system with 70% cooleant and 20% water. remove the radiator cap and start the engine allow air bubble to escape from the system while the engine is on but do not allow the coolean to over flow from the radiator. replace the radiator cap as soon as you see steam coming from the cooleant. another way is-- you can keep the radiator cap on and loose the bleeder valve that is located on the thermostat side and the other at the back of the engine near the fire wall or crow. Also check the thermostat. make sure it is in the right position and the little opening on the thermostat is not clog and the spring is pointing toward the engine. also make sure that thermostat is right one for your car.

Cold and no heat


This is a common complaint for the 4.3 v-6 by GM, what happens over time is air gets into the cooling system, usually a small coolant leak at the intake manifold gasket. Ait gets in the cooling system and starts electrolisis. From this the coolant starts to solidify. If I'm correct your heater core is plugged. Remove the radiator cap (engine cold only) and inspect the coolant. The proper color should be red. If the elctolisis is taking place the coolant will turn to rust and look like mudd. If you find mudd in the radiator, most likely the heater core is plugged. This is a very expensive repair. You'll need to remove the raditor & sent it out to be boiled out. Replace the heater core, thermostat and the coolant hoses. You'll also need to perform a "prestone" flush. You may need to flush the cooling system monthly until the system is clean.
