92 Cadillac Deville Overheating


Let the engine cool, remove radiator cap, start the engine let it warm up.
Make sure the radiator is full. Look in the radiator for a bubbling mist. that is the sign of a bad head gasket. Also caddies with aluminum blocks require special coolant.

92 deville I've replaced heater core heater control valve water pump thermostat raditor and recovery tank and cap . had a pressure check to se if a headgasket. Have no coolant or oil mixing no white smoke...


Hello: ONE OTHER THING YOU MIGHT DO IS GO TO A AUTO PARTS STORE AND PURCHASE A SNIFFER KIT TO CHECK YOUR COOLING SYSTEM FOR EXHAUST GASES WHEN THE ENGINE IS AT OPERATING TEMPERATURE. THE KIT COMES WITH INSTRUCTIONS. IF YOU DON'T WANT TO BUY THE KIT MOST GARGES CAN PERFORM THE CHECK. A PRESSURE CHECK MAY NOT ALWAYS SHOW A LEAK OF A HEAD GASKET

Trying to remove the waterpump pulley on a 92 Cadillac Sedan DeVille 4.9 V8


  • When replacing a water pump, it is necessary to drain the cooling system.
  • Any components--belts, fan, fan shroud, shaft spacers, or viscous drive clutch--should be removed to make the pump accessible. Some pumps are attached to the cylinder block as shown below.

  • Loosen and remove the bolts in a crisscross pattern from the center outward.
  • Insert a rag into the block opening and scrape off any remains of the old gasket.
WARNING When working on the coolant system (for example, replacing the water pump or thermostat), a certain amount of coolant will spill on the floor. The antifreeze in the coolant causes it to be very slippery. Always immediately wipe up any coolant that spills to reduce or eliminate the chance of injury.
  • When replacing a water pump, always follow the procedures recommended by the manufacturer.
  • Most often a coating of good waterproof sealer should be applied to a new gasket before it is placed into position on the water pump.
  • Coat the other side of the gasket with sealer, and position the pump against the engine block until it is properly seated.
  • Install the mounting bolts and tighten them evenly in a staggered sequence to the torque specifications with a torque wrench. Careless tightening could cause the pump housing to crack. Check the pump to make sure it rotates freely.
  • The water pumps on many late-model OHC engines are driven by the engine's timing belt. When replacing the water pump on these engines, always replace the timing belt.
  • Make sure all pulleys and gears are aligned according to specifications when installing the belt.

I have a 92 sedan deville, the problem i am having is very low heat.The heat is warmer at idle but cooler when driving. I have replaced the water pump, thermostat and flushed engine out.


remove the heater hoses from the connection on the bulkhead and flush the heater rad out ,if it still doesnt work then block the bottom outlet off with a cork and then using a funnel and piece of hose connected to top outlet use a 20% caustic soda solution to fill it with and leave half hour then flush it out again.fancy wasting money on pumps and whatever else ,why didnt you ask me first

Water pump still leaks 92 cadillac deville


yes always use gasket sealer on both sides of the gasket. and make sure the old gasket is completely removed but do not use a chisel ar anything as you will leave gouges in the metal and cause a leak. Best to clean it is with some sand paper and just take your time. And just a thougtht but all i use is the black gasket sealer. It seems to wwork the best.
