Question about 1988 Pontiac Grand Am

1 Answer

My coolant light is on. I filled the radiator and it is still on. I let the car run a few minutes and it seems to get to normal temp and show no signs of over heating. The car is a 1988 2.4L Pontiac Grand AM SE.

    I did fill the tank to the line. I did some more research and found on your site that banging on the tank at the sensor jostled it lose and the light went out.

    Did you fill the coolant recovery container up to the full line? There is a hose just below the radiator cap follow it back to the plastic coolant recovery tank, and it should say engine coolant on it. Check to see if it is filled with coolant up to the full line, which is usually marked on the side of the recovery tank.

Coolant level sensor is old, replace.

    This is temporary as the scale buildup inside it from not using distilled water will get it hung up at some point and usually put a whole in the float to warrant replacement so be aware of that.

My radiator has coolant bubbling out of the upper corner sort of where it connects to the upper hose. Is there a gasket or oring there? Does bubbling mean there's air in the system?


Your radiator has got a damage. For a short term you can use liquid rad seal; but is to be repaired/replaced. When engine/coolant temp is rising volume/pressure is rising too, excess usually goes to expanding canister, but since there's a hole in rad, it gets spewed out.

2003 kia sedona ex heat not working


If the engine temp rise while sitting at lights then you have an air flow through radiator problem. Electric fans not working or viscous fan hub is faulty. high heat except at speed may indicate an air lock in the cooling system or coolant level in the radiator. Check at radiator cap not the reservoir.

The temperature off and on runs hot and at other times is seems normal. i added coolant and let the engine get hot and could not replicate the problem after that. can't see that there is anything on...


Let the vehicle cool off completely, then remove the radiator/surge tank cap and fill it to the indicated full level. Leaving the cap off, start the engine and allow it to run until the temp gauge reaches normal, about 10 to 15 minutes. Place the heater on high, observe to see that you have good interior heat, and top off the radiator/surge tank. Reinstall the cap and drive it, observing the temp gauge. If it is still not right, stop and squeeze the top radiator hose-it should be difficult, if not impossible to calopse, and hot. If it is easy to calopse, you have an internal, or external leak, or your cap is not holding pressure.

Radiator Reserve Tank


Your engine is pressurizing the coolant system through a leak in the head-gasket, it could be airgaps but I'm going to be your head gasket needs replacement.

My coolant expansion tank is overflowing after 20 minutes running


There could be a couple of reasons for this,

1. The thermostat could be stuck closed creating more pressure than normal. Your temp guage would show a higher temperature or you have another blockage in the system.
2. The expansion tank is too full.
3. The cylinder head may be leaking. If you fill the system run the engine to normal temperature with the radiator cap off, look for quite large bubbles coming out of the filler cap. If the head is badly leaking, they can be like a volcano. The temp will rise quickly from cold and the engine will overheat in a short distance.
It does seem odd that it would only spill over after 20 mins. Suspect that the expansion is over full first if your temp is normal. Let it run until it stops and see where the level is when the engine is cold.

Temp Gauge Creeps Up


I would take it in and have then do a block test to be sure you don't have a head gasket issue, Does the coolant get low after a few days or so. This could be a sign.
Also sometimes its hard to get all the air out when you drain the coolant and fill up. Be sure the coolant bottle is up to the ok line..
And if everthing checks out ok then maybe your ready for a water pump. The fan blades on them tend to wear down then they dont pump water too good.
Lastley your radiator could be clogged.
Best bet is to go to a shop and pay the 50 bucks give or take and let them tell you whats wrong

2001 dodge stratus engine temperature gauge spikes occasionally


Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

you have air trapped in the system.
Park facing uphill (on car ramps if you have them).
with cold engine, remove radaitor cap and fill radiator.
Fill reservoir.
leave cap on loose.
Turn on heater.
start engine and run until upper radiator hose gets hot (meaning thermostat has opened).
Check coolant level and top off. Repeat until temp gauage reads normal and heat is coming from heater ducts.

Temperature/heat wont work/dashboard lights on and off


It sounds to me like you're low on coolant. When you checked the coolant level, did you actually open the radiator cap and make sure the radiator is full? The plastic tank you generally add coolant too is actually an 'overflow' or 'reserve' tank. There is a hose that runs from that tank to the top of the radiator so if the radiator gets low on coolant, more coolant -should- run in from the overflow tank. However in practice this does not always work. I have a Jeep that leaks coolant and experiences this exact same problem. Coolant will not run from the reserve tank into the radiator because the hose is plugged up, and whenever the radiator gets low on coolant the temp gauge will go real high and then drop, and the heater doesn't work well. This is because the cooling system of your car is supposed to be a closed system, full of coolant and no air. When coolant leaks out, the space it used to occupy is now occupied by air, which does not transfer heat well. When 'air' is passing through your cooling system, no heat can be transferred from your engine to the heater and radiator, resulting in a hot engine and no heat at the heater. Then when a pocket of water passes through the system, the temperature gauge quickly falls as the water absorbs the heat from the engine. The hot water that cools the engine is where the heater gets it's heat from as well, so when water passes through the heater core, the heater works, but when it's filled with air, it doesn't.
