I believe you have a pocket of air in your system. This happened to me before and I had all the same symptoms. I realized I was going to have to push water through the system manually to get it out. When I changed my water pump and hooked everything back up, there was no flow of coolant through the system, so I made sure when I hooked the hoses back up there was no air in them by pouring coolant into them. If that doesn't work, you can use a garden hose to force start the coolant.

SOURCE: Water pump problem?

You need to make sure you don’t have an air lock. Find the bleeder valve for the coolant system and release the air. If you can’t find the bleeder, find the highest hose for the coolant system and make sure coolant is flowing through it.

Have the cooling system pressure tested. If it holds pressure, that's a good thing. If it doesn't hold pressure, you may have a leaking head gasket. What may be happening is the crack in the head gasket could be blowing hot air into the cooling system causing it to overheat.

You replaced the head gasket but did you get the head or heads checked for cracks or check the block for warpage?

possible blown head gasket, have a leak down test done to see if there is bubbles present in the radiator when looking in through the radiator cap hole. you can also remove spark plugs and see if there is any water or moisture present on plugs.
even though you may have flushed your radiator ( I presume that "you" have done that) there may still be a few bars blocked with dirt etc, you may have to have the top and bottom tank removed and have the individual bars cleaned to make sure there are no blocked bars.
Hope this helps

Why is my car running hot 2002 buick century

Just ideas Is the fluid up where it should be in the radiator. Is the thermostat working properly. For the cost I would start there with a new thermostat.
Is the radiator clean inside and out. Maybe should be flushed under slight pressure. Outside radiator could be plugged with bugs and garbage. Are there any kinked hoses? Is the water pump working properly. Check all drive belts for being loose These are just ideas to look at.

Changed thermostat water pump and radiator on my 2001 Buick Century but still keep running hot...what else could be the problem???HELP PLEASE

Check to see if the radiator fan is on when the AC is on. The new thermostat may have a higher operating temperature than the old one. The thermostat could have been installed upside down. The gauge is defective and reading the wrong temperature.

Car running hot

Probably a cracked cylinder head or block, or both. Or the head was warped and the head gasket has blown again.
When the engine gets very hot the gasket expands, and after a few times it will not return to its original shape.

Where is 2003 buick century sensor located

Before you did any repairs to address your overheating problem, did you check to see if your fans were working at all ? One way to check if they are working is by starting your vehicle and turning the A/C on, they should automatically start running. If they do not, begin to perform diagnosis to that electric circuit.

Maybe a thermostat..or the heatercore clogged up..If the vehicle runs hot pretty quick then its the thermostat stuck closed..If the vehicle is not running hot,but you have no heat then the thermostat will be stuck open or the heater core not circulating

Engine over heats 2000 cadallic deville northstar engine

flush your radiator first.with the thermostat out you should see the water moving if not bad water pump.this engine needs the thermostat to function properly and either a 50/50 coolant or straight coolant so it does not boil over.also make sure your fans are coming on

My 2000 buick century is over heating fans are running i also have a hard shift after about 30 min of driving are they related ?

Hi, these are two separate issue here.

The abnormal shift is isolated within three ares. i would suggest checking the transmission fluid level first to make sure of the proper level. if its low, you will experience Miss shifts of this nature. if the fluid level is sufficient, i recommend moving your inspection to the TCM(transmission control module). this is the control module that initiates the correct shifting intervals and it relays the actual shift signal to the shift solenoids located inside the transmission pan. if the module is malfunctioning, it will affect the shift patterns dramatically. If the module is in good condition, i would then move on to the actual shift solenoids themselves.

These devices preform the engaging of the gears within the transmission as stated above. if this device is not working or is malfunctioning, it will affect the way the transmission shifts. If you have not preformed a proper transmission flush and have not changed the filter for a while, it would help if this maintenance was initiated soon if possible.

Now, concerning the overheating issue. if the fans are running in a correct manner, this will most likely point to a faulty water pump or an faulty thermostat that may be froze(stuck in position not allowing proper water flow). the most common fix will be to preform a radiator flush. during this flush, if you notice a rusty water flow and tiny metal fragments running out the radiator, this will confirm extreme radiator damage to the inner coils and it will have to be replaced or rebuilt. I would recommend flushing the radiator and testing both the water pump and thermostat for there operational value.

Please rate and god bless:)
