You will need to replace that particlar pipe. I would replace all including all hoses if 5 years or older. Antifreeze & thermostat too

Cadillac deville pouring transmission fluid


transmission lines to radiator is leaking. The radiator will help cool the transmission fluid in most vehicles, and these lines can get crimped or become loose during normal vehicle maintence. Replace the lines and connectors, and recheck transmission fluid level. MIght just be a loose connection you could possibly tighten up. Busted or cracked radiator?

Coolant leak


Pressure test the cooling system to determine exactly where the leak is coming from first. Cadillac 4.6L engines have been known to leak externally from the head gaskets.

On my 96 deville i have a coolent leak coming from passenger side of engine towards the fire wall by front tire


Hello: Check the coolant overflow tank, the hoses and the metal pipes the hoses attach to. If there is bubbling in the tank after driving the you may be low on coolant or have a blown head gasket problem.

I have a 1996 DeVille with a coolant problem. I have replaced the air compressor, radiator, thermost at, serpentine belt. Car has run as hot as 255 and as low as 195 degrees. I am using up about 2 gallons...


Did you check the hoses to see if they are tight? The bottom of the radiator may have a leaking hose as well. Check the freeze plugs to see if they are leaking. Also check the cylinder heads for any leakage.

I need step by step instructions on how to


1990 Cadillac Deville 4.5L FI 8cyl Repair Guide

CAUTION:
Never open, service, or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. In addition, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

4.5L and 4.9L Engines
  1. Drain the coolant to a level below the thermostat housing.
  2. It may be necessary to remove the upper air filter assembly on some models.
  3. Remove the 2 bolts securing the upper thermostat housing to the lower housing.
  4. Remove the upper thermostat housing.
  5. Remove the thermostat and O-ring from the lower housing.

Fig. Thermostat installation-4.5L and 4.9L engines


To install:
  1. Install the thermostat and a new O-ring to the lower housing.
  2. Install the upper thermostat housing to the lower housing. Tighten the thermostat housing bolts to 20 ft. lbs. (27 Nm).
  3. Refill the cooling system using a 50/50 mixture of water and ethylene glycol antifreeze.
  4. Start the engine and check for coolant leaks. Allow the engine to come to normal operating temperature. Recheck for coolant leaks.

Hope helps with this (remember rated this) Good luck.

Brakes lines rusted on a 97 cadillac deville


Metal brake lines rust with age, become potted & leak fluid. Replace with copper pipe, is only marginally more expensive, the labour to replace will be the same but copper wont rust, so future cost saving & safety. Job is easy enough to do yourself, unscrew where it joins master cylinder, then follow line back, clipping it out from any securing clips, unscrew other end, coil up & take to motorfactors, ask them to make a copper brakepipe exactly like your old one, dont worry if you snap pipe during removal, take all bits with you so correct length can be gauged. Copper is very flexible & can be bent to shape when you refit. Make sure you have new brake fluid to bleed your system with after replacement.
Have fun.
