North Star Blown Head Gasket

The Northstar Condition

The North Star engine rarely exhibits typical blown head gasket symptoms. Initial overheating issues can usually be traced to component failure and repaired. This corrects the problem for a while and the first indication of some residual problem begins with a low coolant warning.
The car runs great so you add coolant and don’t think too much about it. You check for leaks under the car and everything looks good. Your mechanic checks the cooling system and also finds nothing wrong. The coolant seems to have just disappeared.
As the distance between low coolant warnings gets shorter and shorter you begin to have episodes of overheating. There is little time from between the low coolant warning and before the temp gauge starts to rapidly climb. Usually this sudden rise in temp is followed by a rapid fall in temp (back to normal). This is again followed by a rise in temp, but this time it doesn’t come down.
With the car engine overheating, it is only logical to conclude that some component in the cooling system has failed. Although there is no indication of what is causing the problem, mechanics frequently suggest replacing the water pump. When the engine still loses coolant and overheats the frustration mounts. Next you replace the thermostat, but no luck. Finally, you install a new radiator but the coolant loss still persists.
With nothing left to replace, you’re told that you must have a blown head gasket and must replace the North Star engine.

Your search for options quickly becomes a financial nightmare. Since replacement or repair cost can easily exceed the blue book value of the car. Steel Seal Northstar is the solution for blown head gasket repair for your Cadillac Northstar V8 engine.

Typical sequence of events

The North Star engine rarely shows symptoms that are typical of a blown head gasket. Initial overheating issues can usually be traced to component failure and repaired. The first indication that some residual problem still exists begins with a low coolant light.

  1. Car engine overheating.
  2. Cooling system is repaired.
  3. Low coolant warning appears.Mechanic find nothing wrong.
  4. Low coolant light re-appears.
  5. Engine does not overheat as long as the coolant level is maintained.
  6. The engine still runs good and has plenty of power.
  7. The Distance you can drive starts getting shorter and shorter.
  8. Replacing other components in the cooling system has no effect.

The Solution – How it Works

Step #1:
Install Steel Seal’s cooling system modification kit. This will eliminate air pocket formation. Air pockets that develop while the engine is overheating under high demand (freeway speeds) cause the thermostat to malfunction and close. Coolant flowing through the radiator stops causing the engine to overheat. The head gasket cannot be repaired as long as overheating conditions exist.

Step #2:
Add part A and B of the Steel Seal Treatment to the surge tank.
Drive immediately (60 mph, 3rd gear, for 5 miles)

  • Sets at high RPM’s under load.
  • Reinforced graphite composite
  • Two part sealant catalyzed at 2500 rpm’s
  • Forms high strength flat surface bond insuring tight seal around stretched head bolts
  • New thin layer technology developed to seal high volume exhaust leaks. This allows the repair to take place while the engine is under high demand.
  • Reinforced with high temperature aluminum silicate fiber
  • Able to withstand temperatures up to 3700 F
  • Maximum repair density achieved by driving 60 mph, in third gear, for 5 miles
