SOURCE: used cadillac deville

i would suggest having the car towed to a shop before purchasing it. have them check the water pump first and because it has the north star engine they need special tools to fix it

SOURCE: my 2001 Cadillac Deville got head gasket leak, how

Hello: You add the sealer to the tank on the passenger side under the hood. I don't recommend this as a proper repair. You may create problems with reducing the flow of coolant through the radiator. The best way is to replace the head gaskets. The tank has a radiator cap on it.

i would have the head gaskets replaced, this way , you know that there won't be any more leaks, and sometimes , using the sealer, might not work as good as you need it too.

SOURCE: Overheating - 1999 Cadillac Deville

is the cooling fan operating properly(on and off at proper temps),does the rad have a flow problem this can cause it as well.you don`t say when and how long it takes to overheat.sitting idling for long periods of time,driving in the city only,on the highway,coming off the highway,only on acceleration,only with the a/c on.all these factors can make a difference in finding the problem.have you told the shop when and how its overheating.you may have to drive it under the same situation to get it to over heat and take it to the dealer and have them check it out when its happening or take it to a shop as dealer techs won`t spend as much time on it as they should because they are paid flat rate and if nothing shows in short order they kick it out the door and move onto a paying job.

Just bought a 2000 Cadillac deville an I drove it 5 min. and it started over heating...the previous owner put a new radiator and thermostat in and said the heads was not blown..


he could be right about the heads but he may have put the thermostat in wrong and instead of opening it is blocking the coolant flow causing the overheating
The time span quoted is about right for a thermostat to start opening

1998 Caddilac DeVille overheated water in the oil blown head gasket. would it beworth fixing.


It depends if you really like the car or not how much it costs.and how many original miles your engine has on it now. It might be less expensive to find and put a good low mileage used motor in there instead vs. replacing the Head Gasket and rebuiling the Head.

How do i repair a blown head gasket on my 1992 cadillac deville V8 4.9L


The correct way is to remove the head(s) have the head(s) checked for warpage repair as necessary then clean everything good and replace the head gaskets. There are some places that advertise a product that is suppose to seal a head gasket leak but remember if it seals the headgasket leak it may stop up your radiator, also it will just be a temporary repair

Overheating. i put in a new thermastate, clutch fan and a new radaiator cap, and today i flushed out my radiator


Hi have a pressure test done on the cylinder head to rule out a head gasket failure, also check the water pump, and last make sure the coolant system has been bled properly,

Hope this helps
