I own a 99 poniac grand and I blew a gasket than changes them. After I had put the car back together the car acted like it over heated again although this time it ONLY RAN for 10 min then there went that head gasket. The water pump was bought in Jan. and the thermostate has been changed ANY IDEAS what is going on?

all parts that I have bought for the car are new I DO NOT buy used because I KNOW you can run into more troubles this way

you may have air in the system it may have a bleeder on it
you may have to replace the t-stat again
I use a funnel to put the coolant in the radiator and keep it almost full to the top and squeeze the upper and lower hoses to get the air out
good luck

did you purge the air out the system?? that in it self can cause a air pocket that can cause a overheat condition. there is a procedure to remove air from the cooling system. another thing to look for is if the fans are working? are they?
start the car - then turn on the AC - does the fan come on?
the AC fan or the AC portion of the fan if it has only one electric fan is used by the computer in extreme overheating conditions...so if that is working you might want to see if the TEMP Switch is working properly , not the one for the gauge that tells you how hot it is - the one for the computer - that is a 2 wire one i think . I think you can jump wire it with the key in the ON position and it should turn on the fan if it don't there might be another way to do it i cant recall.
If you disconnect any computer wires it will turn on the CHECK ENGINE LIGHT with the key in the ON position - don't worry about that.
Id start with the air purging of the coolant 1st, then make sure the fans are working. If all else fails take it to a repair facility.
Good Luck.

Sounds like when you blew the first gasket, you warped the cylindar heads, which would explain why you are having a tough time maintaining an acceptable temperature control.

Have you changed a head gasket before?
Are you buying new parts, instead of used... also have a professional look over what you did, you may have missed a step.

was the head checked by machine shop for warpage and cracks? also the radiator should have been sent out for clean and flow test, I sometimes have problem bleeding air from coolant after repair, are you sure the head gasket is blown again,(white smoke) or maybe just overheating due to improper bleeding air from cooling system

the first thing that you did wrong was to have the head milled you can't resurface an aluminum head even though they make it flat again once it heats up again it goes right back warped and you end up blowing the head gasket again. you are going to have to put another head on it.

why dont you ask the company guys for a change? maybe you forgot the coolant or the lubricant somewhere

if you do a compression test and it low then you have cracked the piston ring's water +oil in the rad
