How to Repair a cadillac engine that overheats
On this video I'm repairing a 2002 Cadillac Deville 4.6 lt northstar
engine. Customers complaint was that the cars temperature would be good at
idle but once the car was on the road it would overheat
Another Reason NOT TO BUY A NORTHSTAR 4.6L Cadillac
I don't know why a pulley that controls the top cams would be made of
plastic instead of steel... but after the tree pull it sat for a week or
two then this happened. I have since pulled the motor and started taking
it apart for scrap... its a bad design from the start the heater core has a
section that says CUT here for service... the headers on the back cant be
removed without dropping the transmission. Tell me one good point about

Zero to 60 Run--4.6 Cadillac Northstar V8 vs. 4.9 OHV V8
Zero to 60 comparison between my new 2001 Cadillac Seville SLS with a 4.6
Northstar V8 and the 1991 Cadillac Sedan de Ville with a 4.9 that I've
owned since 2005. The Northstar in the Seville is faster, especially at the top end, but the
good old 4.9 in the DeVille holds its own--especially for an 18-year-old
car with 257,000 miles on it.
Judging from the time codes in the video, the Seville did it in 7 second
flat; the DeVille is just over 9 seconds.
Interestingly, both cars shift from 1st to 2nd at 45 MPH, and both hold 2nd
gear all the way up to ~80 MPH. Without a tach in the DeVille, I have no
idea how high it was revving, but it probably went close to redline.
The noise you hear besides the engine revving in the Seville is raindrops
on the windshield. I had the camera on a tripod held down between my legs
in the Seville; in the DeVille, it's just handheld, so it's shakier.
Both runs done on Stapleton Rd. just south of Monmouth/Independence, Oregon
1994 Cadillac Eldorado Head Gaskets
We have replaced the Head Gaskets on a 1994 Cadillac Eldorado. We ordered
the helicoils but then on different blog we found out that its not a good
idea to use those, so instead head over to your local Cadillac dealer and
they have the proper thread inserts to perform this job. The specs are all
the same. I will try and get the torque specs as soon as possible on my
site. Check out our web site @ http://www.detroitdownrivercustoms.com
Cadillac head gasket repaired
You check for leaks and everything looks good. Your mechanic checks the
cooling system and also finds nothing wrong. In fact, most Cadillacs can
idle all day and not loose a drop of coolant or overheat. However, as soon
as you get on the freeway the temperature starts to go up and the low
coolant light appears again. When you check the coolant level it's very
low. Frequently requiring a gallon or more to refill. Without any clear
indication as to what's causing the problem your mechanic may suggest
replacing various cooling system components. Again, this may resolve the
problem for a while, but soon the low coolant light re-appears. What to do?
