Did you bleed the air out of the system? there are a couple bleeder screws in the cooling system that have to be opened up so that the air can be bled out. one should be by the thermostat housing and there will be one or two more around the engine. usually on a coolant rail going to the heater core. with the engine running you will have to open them up till you get coolant coming out of them. You may have to do this a couple times in order to get all the air out. this should help you get pressure back in your system.
Let me know if this helps you out.

How to back flush heater core 2007 grand prix


drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.

I have a 96 grand marquis i just changed the radiator and the coolant is not flowing through the hose to the thermostat and the hose at the bottom of the radiator what can i do?


check water pump with car OFF try spinning the fan if spins free check thermstat if not i would say change water pump i would suggest changing them both your looking about 50 bucks for a water pump and about 10 on thermostat (i would get a fail safe, if it breaks it locks open so theres no engine problems)

1999 grand prix gt overheating. Changed thermostat, water pump, upper radiator hose. Please help!


does the upper and lower hoses seem to be the same temp when car begins to overheat? ore the radiator cooling fans coming on before the car overheats? did you pressure test the cooling system and radiator cap? also may want to remove the lower hose and flush the radiator. is the check engine light on and does it run bad?

The temp gauge on the instrument panel was


Sounds like the radiator is clogged, have the cooling system flushed, the water pump pumps water into the engine and it comes out the top hose to return to the radiator to circulate through it to cool, if the radiator is clogged the water pressure will build on the top hose, also look at the bottom radiator hose, if it collapses when you rev the engine the radiator is clogged, although sometimes the bottom hoses are reinforced with wire to prevent them from collapsing so just because they do not collapse it does not mean the radiator is not clogged.

99 grand am gt overheating changed thermostat and


try priming the engine block & radiator with water though the hose's & any hose you can squeeze to pump out the air lock with the filler cap off when running, sounds too much air is is in the system & the pump won't work dry.
I had this problem a few times & I ended up practically forcing water into any hose I could re-attach quickly using a garden hose, as the heating system need's priming too !

Engine overheating


The best way to flush it would be to take off the bottom radiator hose and pump water through the fill nozzle after all the coolent is out you can then hook the hose back up and replace it with new coolant.
