SOURCE: 1999 cadillac deville overheating

my husband did everything that everyone else did that had this overheating problem. It was so weird that my engine cooled at a light and heated up going down the road. I have a north star 4.6 engine and this is natorious for happening. my check engine light also came on and so I had a diagnostics done which told me my #1 injector wasn't firing , car ran like **** as well. After putting in a new water pump and plugs,ect. and realized injector was good a friend told him we could have a blown head gasket. So just to see if this was the problem I went to buy a bottle of glassbeads and the auto parts guy told us to purchase a bottle of BARS STOP LEAK BLOCK SEALER NOT RADIATOR BUT BLOCK SEALER $31.99 . He followed the directions and we waited 24 hrs. before driving it. What ever the problem was has stopped my car runs like brand new and I am loving it again. no over heating no injector problem, runs great.......I hope this helps. I know its probly a temperary fix but its a fix and now we know what the problem was. SASSY

SOURCE: Problem with overheating on 1996 Cadillac Deville with Northstar

The oil life resets to zero after the engine overheats. Check for external leaks first, make sure the water pump belt is still there and turning. The most likely cause if the car has over 70,000 miles is head gaskets.

SOURCE: how to replace the thermostat on 2001cadillac deville

4.6 Northstar V8. It is located on the rear of engine (driver side) in front. It is 1n the the waterpump housing cover. Remove airbox and intake tube and bottom radiator hose. 2 bolts(believe 10mm) on thermo housing. These systems are a lil finiky about air pockets....so fill slowly and let run at idle until operating temp and let cool and chk level.....fill as needed and repeat if needed.

I just need to a general idea of where the starter is im gonna change it out is it under the thermostat on the left side of the motor on the tranmsn. side right? i have a 2001 cadillac deville.


If you have the NorthStar engine then then the starter is under the
intake manifold, no I am not joking. You have to remove the plastic intake
plenum to replace the starter, its a pretty big job and I would not advise you to do it yourself unless you are trained.

Where do i find the thermostat and how do i replace it on a 2001 cadillac deville


The thermostat in the northstar engine is located at the bottom radiator hose (unlike most conventional cooling systems), the hose connects into the housing where you will also find the water pump.
Remove the hose from the housing,then remove the two bolts on the flange,the thermostat can then be pulled out.
Take note of the orientation of the thermostat as you remove it.
Don't forget the new gasket, you may have to order this separately.
