Question about 2003 Pontiac Grand Am

1 Answer

Constantly adding coolant, lowcoolant light will come on, therefore getting hot all the time.It makes a popping sound kinda of like if you were boiling water in a big pot and the water all evaporated and the heat was still high-the pot would pop. Its bogging out-like say you were stuck just slipping on ice and in the process of trying to get out it bogs-there may be even a bit of a spudder,.the signal lights wont work, but mayb that is because i took out the cigarette lighter to see what was wrong with it, which i still havnt figured out PLEASE HELP ME THANK YOU

You either have a head gasket that is leaking,water pump leaking,radiator leak,you don`t say if there is any coolant under the car indicating a leak.you may have to have the cooling system pressure tested and checked for leaks.the popping sounds like air in the system when overheating.as far as the signals it may be a fuse or a flasher you don`t say if they worked before you took the lighter out.the cigarette lighter works with a fuse that may or may not operate another system.there is only one wire that attaches to the center of the socket that is the power wire and a ground wire that is usually connected to the side of the socket at the end.lighters will stop working if the heating element is burnt out(the part that you light the cigarette),it will not necessarily show.so if you have power on the feed wire and the ground is good then the chances are good the lighter assembly will need to be replaced.

    If your GA has a 3.4L V6 and uses Dexcool, your problem may be the lower intake gaskets. Dexcool is nasty stuff and is known for being the cause of those gaskets going bad! I replaced those gaskets twice in my car before I completely flushed out the cooling system and replaced the coolant with regular coolant (the green stuff). Note: NEVER mix regular coolant with Dexcool! Will gel and cause bad problems! You can replace the Dexcool with other coolant, just make sure to completely flush out all of Dexcool before replacing it with regular coolant.

Oil in radiator? 1999 festiva auto


Sounds like you may have a blown head gasket. Did your motor recently get hot or over heat? Those symptoms point to a blown head gasket. Your engine oil is getting into the coolant and coolant is most likely getting into your oil. Kinda looks like chocolate milk?

Having to physically pour coolant every few days,winter and summer,


I assume the coolant is low when u install fresh coolant. ( No pun intended) The cooling system is a sealed system, if u are adding fluid constantly it either means u have a leak or it's burning it. Do u see any leaks, puddles or smoke coming from the engine compartment? Is the coolant mixing with the oil or visa versa, or a hot running engine? could be head gasket. Check spark plugs for coolant or oil. coolant leaking into passenger floorboard? Heater core. Poss coolant switch. If no luck, have the system pressure checked by a shop & stop wasting $ on coolant. good luck.

AC cold on passenger hot on drivers side


Sounds like multiple problem's. The a/c sound's like low on freon.The air bag and ses light are seperate systems from the a/c.Any time the service engine light is on it has to do with the engine system,the air bag is also seperate.Need to take in and have the code's checked for the service light and they can also check the air bag system and see what codes are stored and go from there.

Low Coolant light always on put new coolant in and it disappears


where the coolant is going and why the gauges go nuts are probably not the same problem. sounds like your gauges have a problem with the ground side connection to power. you could look at the negative battery post and see if it is really gunked up, might as well check the positive side while you are looking. if the battery posts get oxidized pretty much everything gets a not so great connection but gauges are one of few places you notice it. the car only runs off the battery at startup or if momentarily car is using more amperage than alternator can provide, but current runs through battery from alternator so bad connection there will cause whole system to function less than optimum. in the cooling system one component you don't mention replacing is the heater core. you say the coolant is not on the ground, so where can it be? pull your oil dipstick and see if your oil looks like oil. if it looks like vaseline, kinda white and creamy, you just figured out where your coolant went and you have a blown head gasket. hope that's not it, it's sort of a hassle. there aren't too many other places for the coolant to go. it either runs on the ground, boils off against the hot block, like if it comes out near an exhaust manifold (and that makes quite an odor) or gets into the oil through blown head gasket. it can make it into the passenger compartment through a leaky heater core and if that happens you will smell a sort of sweet smell in the car and after while get a green cast to condensation inside windows. hope that helps.

No heat


if you replaced the thermostat, you have an air bubble trapped in the engine. So, you don't have any coolant running through the heater core, therefore no heat.
sometimes hard to "burp" air bubble. Try this. Park park facing uphill and jack up front of car too. You want to get radiator opening higher than top of engine. Then remvoe radiator cap (cold engine), fill radiator, then fill coolant reservoir to full point. Install radiator cap but leave it loose so air can escape. Start engine until upper radiator hose going into radiator is hot. This should burp air. Repeat a few times while adding coolant mix (50/50 antifreeze) to keep radiator full. Be careful not to remove radiator cap when engine is hot.
lwt us know how ou make out. There is a more complicated procedure but you need tools and knowledge of where air bleed is on top of engine

1994 CHEVY CAVALIER V-6 STARTS TO OVERHEAT WHEN A/C RUNNING. ALREADY CHANGED THERMOSTAT AND ADDED COOLANT, STILL RUNS HOT, SOUNDS LIKE THE COOLING FANS AREN'T COMING ON WHEN THEY ARE SUPPOSE TO. CONSTANT...


Make sure you get the air out. There may be "high spots" on the engine that you can unscrew to let the air pockets t. Close this small valve when just hot water comes out.
Unplug the radiator fan and use jumper leads to test the fan operation. Use a scan tool to check for codes. If you get a scan tool that gives live data, see that the PCM sees the actual temperature of the engine after 5 to 10 minutes of running. It should see the temp. rising to 225 degrees farenheit.
Replace engine temperature sensor if the PCM doesn't recognize the proper temperature. You ARE going to compare this to the temperature gauge!!!
If all else fails, get the PCM recalibrated or flashed at the dealership.
