Top 20 2004 Pontiac Grand Prix - Page 7 Questions & Answers

remove battery from car. disconnect wires and bolts from starter. Pull starter from its opening. Put new starter in hole. tighten bolts and replace wires. Replace battery. The end.

don't drive it until you get this figured out. If you can jack up each wheel, first check all 4 tires for bulging or cracks. They should all be round and run true, no wobbles. Check that wheel nuts are tight on all 4 wheels. Check for top to bottom movement, and side to side, there should be very little movement. Do this by grabbing the tire top and bottom, side to side and rock back and forth. If these things all check out, you may have more serious problems. You didn't say what the symptoms are, so hard to guess. Make sure power steering fluid is topped up, a little hard to do as you have to move the radiator overflow tank out of the way. If you can't do all this yourself, get someone to look at it who knows what they are doing.

Antilock brake module problem. Replace EBCM.

This engine has problem with gasket .

Could be air lock.

Belt tensioner pulley bearing, most likely.... Remove the serpentine belt then spin the pulley by hand. If it makes ANY noise, that's your problem.... pretty common on GM engines.

hi brenda , if you look down threw the windshield from outside can you see the display on ? sometime the spring that holds the mirror in position for the display wears threw the plastic and causes it to drop thus not reflecting off the windshield correctly ....

What sort of answer are you looking for ? A guess at a long list of possibilities ? Need a repair shop, don't you,to diagnose the issues

The belts may squeal, you may notice reduced charging from your alternator.

Check coolant level,could be air lock!

assume this is the power steering, normally the reservoir for the power steering in with the pump. The pump is usually belt driven and will be near the radiator

This must be a 3.8 liter engine. They have 2 plastic elbows that always break they run threw the alternator mounting bracket. #1 disconnect battery #2 remove serpentine belt by unloading tensioner . #3 remove alternator and mounting bracket this needs to be pried away from cylinder head remove broken pieces and clean passage bores install new elbows with some vasoline on o-rings and align then reassemble. one elbow comes from intake manifold both sides are the same size the other comes from timing cover near water pump the lager side goes into timing cover.

Sounds like the battery is shot. Does the battery pass a load test? A battery can charge and still fail a load test.

All power originates/passes through the master control switch on the drivers door panel. Start by popping the drivers switch and with key on check power going to & through the master switch especially the switch that raises/lowers the window in question. Surely you've done checked the fuses and or relays? Hope this helps.

if you have a power distribution box there is a cable that goes to it that could be corroded and it is not letting voltage through is there power to anything like the horn lights stereo

Heater elbow connector

More likely than not, you have done damaged the engine! Try this, with engine cold, remove radiator cap/coolant jug. Fill with water to proper level and leave cap off, then start engine. If the water/coolant goes immediately to gushing out that means you are getting compression from 1 or more of your engine cylinders into the cooling system from the heads or head gaskets being blown. Also, depending on which engine your car has, (3.4L or 3.8L V-6) if 3.8L engine, they are know to get cracks in the plastic intake around the EGR valve area. Either way, as I'm sorry to say more likely than not, you'r engine has already suffered internal engine damage which can be very costly to fix. If you know how, you can perform a compression test to determine which cylinders are damaged. But, if you are getting water/coolant in ANY of the cylinders, do not drive/run the engine as it will only get worse and cost more to fix. I hope this helps

that would suggest a loose wire connection , the overheating could well be the head gasket , take to a mechanic as there are tests to help diagnose blown head gaskets

Check fluid level.

Low coolant, bad thermostate, bad cooling fan. Blown headgasket but unlikely unless the car was driven hot.
