Many norhstart have very coming problems with radiators,
hold the rpm like 2 to 3 k and if car does not oveheat any more then you need a radiator, but make sure than also there is no air trap on collinf system because they are kind a hard to bleed.
and please leave feedback after tryiging what i said

I have a 99 deville w/ 32valve north star engine and i have problems with it over heating i changed the water pump the radiator and thermostat i have no leaks but it still wont stopover heating


It is probably a head gasket issue if you have replaced the thermo and the pump and it still overheats. You probably can drive it 15 minutes or so and then the gauge starts soaring towards overheat shortly there after. Under completely normal driving conditions. Northstar engine's actually don't overheat not from bad head gaskets (they aren't the defect issue) but the inferior bolts holding the heads to the block. The bolts have been found to be pulling out of the Northstar's soft aluminum block(this is the actual problem but it's blamed on the gaskets). Causing spaces between the block, gaskets and the head that allows hot exhaust air to seep into the coolant flow chambers. This why your have coolant bubbling out of the top of the overflow valve under the hood after only short drives. Under normal operation the engine is literally boiling it's own water supply. The head bolt issue is a design flaw by GM and one that leads to a great number of Northstar engines being crippled at well under 100K miles of driving. Only remedy is to have both heads pulled off the engine, the head bolt replaced with new gasket and you're all set. Bad new very labor intensive whcih = a several thousand dollar repair. I had it happen to my 1998 Concourse Deville. I feel your pain.

Over heating when driving. changed thermostat, changed head gasket, still over heating and now it is hard to start


It is hard to start because the recent overheat causing a gap between the head gasket reducing the compression ratio in each cylinder hence it is difficult for a combustion.
The most culprit of the car overheating is the poor circulation of coolant due to bad pump or/ and clog up radiator. The 2 important things that have not been mentioned are needed to take care of now.

1996 cadillac deville overheat..radiator?


Check for coolant flow at the Purge line,this is a common problem on the Northstar.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.

98 deville runs hot. i have already changed thermostat


You likely don't want to hear this but Northstar engine a common for head gasket failures. One good test that I use it to fill the coolant tank all the way to the top. Then start it up. If the coolant shoots out of the tank. The heads have a problem.
