SOURCE: replacing a radiator in cadillac deville northstar 1997

a drain pan, a hose release tool, flare nut wrenches and simple hand tools, such as a set of wrenches (sae and metric) and sockets with a variety of extensions. it would be helpful to have both 1/4" and 3/8 inch drive sockets and ratchet's

SOURCE: how to change starter

You have to remove the intake manifold as the starter is just underneath it.
Removing the starter itself is quite easy once you have the manifold off.

Unfortunately, removing the manifold is a right royal pain in the back side!!!.
I can list the removal procedure as per the factory workshop manual if you wish?.
The good news is that you do not need to work under the car,everything is done on top.

SOURCE: removing starter from a1999 cadillac deville

Northstar motors are complicated. The starter is inside the motor under the intake manifold.

Does a 1997 Cadillac Deville have a coil pack or a distributor cap

Michelle,

The 1997 V8 engine in the car is fitted with coil packs which are quite visible on the top of the engine. These need to be replaced when they eventually fail as is common.
Here is a video on the coils which may help you.................

Air suspension fuse location 1999 cadillac deville

Cadillac Northstar owners to those whose vehicle is overheating .My 99 Deville was overheating turns out it was Catalytic Converter.Dont rely on PCM for code.If the Cat converter gets plugged up the heat will not get past converter it will back up into engine block causing overheating.My deville ran at between 190 & 201 degrees this morning.If you have a misfire the unburnt fuel goes into Converter and causes damage to converter (blockage).Alot of people overlook converter when overheating happens.

Temp got up to 230 on my 99 cadillac deville is that normal

Make sure your engine is breathing properly, by regularly changing air filters. Flush your cooling system once each year and pressure test. There are cooling lines that cross over the rear of the engine that get corroded and may begin to weep antifreeze..you can view these lines by removing the engine cover....if you've had a consistent odor of antifreeze after running,with no drippage evident, this area is probably the culprit.....love my 99...

I want to buy a 99 cadillac deville and I was told it was only a head gasket problem (blown) what other items should I review before purchasing this vehicle. The owner claims she never let the car overheat...

poor choice if purchased. The head bolts tend to break and to have it repaired is very costly for they are slender and long. . A 99 Cadillac is too old for they have many modules operating this vehicle and the shocks themselves run nearly $1000 each. Back off on this deal

Overheating,eveything looks ok.

I have a 97 Cadillac Deville with a northstar engine and have replaced it twice so far, so i answer this by experience...i've noticed to my two prior engines that went bad that the normal temp should NOT EXCEED 228 (normal), the red overheating light will come on at 250 and at 260 it will beep and tell you to stop engine - idle engine and will begin to smoke (overheat).

I hope this helps you and anyone else...by the way if your asking why did i replace my engine twice is simply because my cadillac is super clean inside and out, immaculate condition.

Alternator

J,
I have a 99 and aftter posting the same question was given some bad info, at a different sight. On the 99 I found it necessary to remove the fan assemblies, drain the radiator and remove , you have to move the condensor for the A/C but it does not have to be removed. I also had to remove the upper plastic piece in the engine compartment and the lower gravel shield. After this is done you will have a clear view of the Alt., mine was the watercooled version, I also replaced all the hoses and belts while I was in there. You may want to have the Alt tested before removal this was a 2 day job in the driveway for me. Mine is also the northstar version , I believe the 2000 is the same.
