You need to replace the upper intake manifold. The coolant will get on top of the pistons and they will not fire. Take all of the plugs out and turn over to get the coolant out and put new ones back in after the new manifold is put on. You can break the starter housing if you don't get the coolant out. A common problem with this engine but the new manifold has been re-designed to last longer.

How do I determine why 2003 Pontiac Grand Prix blows no heat with step by step instructions?


The most common reason is the coolant is low.
Check coolant level when vehicle is cool.
If coolant is low start vehicle and fill radiator with coolant.
if coolant was needed high probability there is a leak
look at all cooling system hoses, thermostat housing, all over the engine to try and find leak and repair.

if coolant isnt low, make sure its not really dirty...reddish mud colored. If it is the radiator is probably clogged and needs to be flushed thoroughly..then refilled with coolant.

there will be two heater hoses coming out of firewall..they are connected to the heater core and one hose directs flow of coolant to the heater core, other hose directs flow away from heater core..start vehicle and run until engine is warm then feel each heater hose as close to the firewall as possible..if one hose is hot and other is cool..the heater core is clogged and will probably require replacement. also look in passenger floorboard if coolant is leaking there..heater core requires replacement.

if you check these things and find none of the issues, let me know, and I will tell you what to check next.
Good Luck with it and if you have any.question let me know

Drained radiator added prestone Radiator flush refilled and started overheating, drained radiator replaced thermostat and now I get no heat from heater,Radiator water is hot


disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec

Overheating


CAR OVERHEATING FIRST CHECK FOR LOW COOLANT IN THE RADIATOR COOLANT OVERFLOW JUG.IF COOLANT LEVEL IN OVERFLOW JUG LOW REFILL ADD COOLANT BACK TO THE FULL COLD MARK.PUT RADAITOR CAP ON COOLANT OVERFLOW JUG START ENGINE LET IT IDLE UNTIL IT OPERATING TEMPERATURE.MAKE SURE TOP RADIATOR HOSE GETTING HOT WHILE ENGINE WARM UP.IF TOP RADIATOR HOSE DONT GET HOT WHILE ENGINE IDLING YOUR THERMOSTAT COULD BE STUCK CLOSE CAUSING CAR TO OVERHEAT.IF TOP HOSE IS GETTING HOT.CHECK FOR COOLANT LEAKS CHECK TOP RADIATOR HOSE AND BOTTOM RADIATOR HOSE FOR LEAKS.CHECK FOR LEAKS AT THE RADIATOR CORES AND PLASTIC SIDE CONTAINERS.IF ALL IS GOOD ENGINE OVERHEATING WHILE IN A LONG TRAFFIC LINE, COOLANT FANS NOT COMING ON.COULD HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR BLOWN COOLING FAN FUSE OR RELAY.COULD HAVE PCM FAULT.MAKE COOLING FAN ELECTRICAL CONNECTORS AND WIRING NOT DAMAGE OR BROKEN.

You could have a faulty radiator cap not allowing coolant to flow to the over flow reservoir. Also check where the hose at the radiator cap connects to the over flow hose as I've seen these get clogged up and cause problems. If you have a faulty thermostat this could also cause a vapor lock in the cooling system and would be apparent if the top radiator hose is collapsed.

I have 2001 alero. Yesterday the coolant light came on and the engine just died. Any ideas maybe fuel pump or timing belt or could it be the water pump


IF LOW COOLANT LIGHT CAME ON ENGINE SHUT OFF BECAUSE IT GOT TOO HOT AND OVER HEATED.WHEN YOU HAVE LOW COOLANT.YOU COULD HAVE LEAKING RADIATOR.YOU COULD HAVE LEAKING RADIATOR HOSES AND WATER PUMP. ADD MORE COOLANT IN CAR RADIATOR UNTIL YOU AT FULL COLD MARK ON THE OVER FLOW COOLANT TANK START THE CAR LET IDLE UNTIL ENGINE GET OPERATING TEMPERATURE.RAISE YOUR HOOD LOOK FOR LEAKS THE RADIATOR PRESSURE WILL PUSH COOLANT OUT WHERE LEAKS COULD BE.LOOK AROUND RADIATOR AND COOLANT HOSES.LOOK AT WATER PUMP.IF YOU SEE COOLANT LEAKING AT WATER PUMP REPLACE IT.

Overheating, boil over when I turn on the heat


Okay! So what I did was cut my car completely off for two days, I drained the radiator by unplugging it, I took the water hose and just let the water flow in and out from the coolant housing under the hood in the right hand corner, I also let the water flow into and out of the radiator, I plugged the radiator back up after just a few clear coats of water flowed through, I filled with 1 1/2 containers of Peak 50/50 Antifreeze/Coolant. I later in the day noticed that one of my fans were out and the other one wouldn't stay on. I ran a kill switch from the inside to the fans, only one is working due to the motor on one of them but I can guarantee that my car hasn't over heated or ran hot since I did this coolant flush. And also when you put the new coolant in make sure that the car is excessively cold. If your fans aren't spinning then that's another reason. I wish you luck.
