NOTICE: 
If  the air  cleaner  is off, a backfire can cause  a damaging  engine 
fire.  And,  dirt 
can easily  get  into  your  engine,  which will damage 
it. Always  have  the  air cleaner  in  place  when  you’re  driving. 
AUTOlMATIC TMSAZE FLUID 
When to Check and Change 
A good  time to check  your  automatic transaxle  fluid  level  is  when  the 
engine  oil  is  changed.  Refer to the  Maintenance  Schedule to determine 
when  to change  your  fluid.  See “Scheduled  Maintenance  Services”  in  the 
Index. 
How to Check 
Because  this  operation can  be a little difficult,  you  may  choose  to have 
this  done  at a Cadillac  dealership  Service Department. 
If you do it yourself,  be  sure to follow  all  the instructions  here, or you 
could  get  a false  reading  on  the dipstick.

it  is  low. 
If you  have  a problem  with.  engine  overheating,.  see “Engine 
Overheating’%  the Index. 
r The  proper  coolant for your  Cadillac  will: 
0 Give  freezing  protection down to -34°F (-37°C). - I .0 Give boiling protection  up to 262°F (128O C). 
0 Protect  against rust and  corrosion.

What to Use 
Use a  mixture  of one-half  clean water.  (preferably  distilled)  and one-half 
antifreeze  that ,meets “GM  Specification 
.1825-M,” which  won’t  damage 
aluminum  parts. You can  also  use  a recycled  coolant  conforming  to GM 
Specification  1825-M  with  a complete coolant .flush and refill.  Use  GM 
.Engine  Coolant  Supplement.  (‘sealer)  with  any.  complete  coofant  change. 
If you  use  this  mixture,  you  don? need to add  anything  else.

Downloaded from www.Manualslib.com manuals search engine The Northstar engine  is designed  to require  less maintenance  than many 
other  DOHC 
V-8 engines.  Engine  systems  are designed to remind  the 
driver  when  service  is  required. 
An oil life  index  indicator monitors 
ongoing  operating conditions and  reminds the driver  when  an  oil change 
is  needed. 
A low  coolant  warning  message  keeps  track.of the level of this 
vital  fluid.  Direct acting  hydraulic  tappets provide  maintenance  free  zero 
lash  operation 
of the 32 valves  from idle to  the  6500 rpm  redline.  The 
camshafts  are driven  by 
a two stage roller  chain  assembly  which  is 
designed 
to provide  quiet maintenance  free Operation.  Platinum tipped 
,spark  plugs increase  the replacement  interval 
to 100,000 miles. 
The  four  valve  per cylinder  design  provides  more efficient  engine 
breathing  which  results  in  higher  power  than comparable 
two valve 
engines.  The central  location 
of each spark  plug ensures  a  fast and 
complete burning  of the  fuel/air  mixture.  The induction  system  uses 
smooth thermoplastic tubes  to channel  air into  the cylinders.  The 
smoothness 
of the  tubes  is  equivalent  to the  elaborate  port  polishing 
methods  used for race  car engines.  Careful design  using  the  shape and 
length 
of the  tubes  boosts  horsepower  by using  sonic  pressure waves 
created  by the  motion 
of the  inlet  valves  to increase  the amount of air 
entering  ,each  cylinder. 
The  Northstar  engine is also designed 
to be very durable. The aluminum 
block  has cast-in-place  iron cylinder  liners  for greater  wear  resistance. 
High  strength  connecting  rods support  the  free floating  piston  pins  in 
bronze  bushings  for superior  high speed  performance.  The fillets 
of the 
nodular iron crankshaft undergo 
a high  pressure  compression  rolling 
operation  to improve  their resistance  to fatigue. 
Quiet  operation  is enhanced  by the  use  of special  materials and  designs. 
The front cover of the engine  is stamped from laminated  steel which 
damps  out noise.  Special  cam  cover  gasket  seals  isolate  valve  train 
operation.The  fuel injectors  are placed  inside  the induction  system 
housing 
to eliminate-  the clicking  noise  which  is  common  to other  fuel 
injected  engines. 
The  Northstar engine  is  designed to provide  years  of efficient.  reliable. 
satisfying  operation.
