OK - so everything is put back together now and naturally the battery is dead from opening and closing the door after not driving the car for almost a month.

Question about the filling process. What Magnum's article suggests and TIS suggest seem to differ.

Magnum:

  • Mix the proper mixture of coolant and water, I used 50/50.
  • Fill the expansion tank SLOWLY until the dipstick tells you it’s full.
  • Put the key in the car, turn it to position 2 and turn the heater temp up to 90 degrees and put the fan speed to nothing.
  • Now start the car.
  • Go back to the front and SLOWLY refill coolant as needed until the dipstick says full, refill as necessary.
  • Once the cars temp has hit the first white notch on the gauge, have your helper rev the RPM’s to 1000.
  • You’ll start to see bubbles coming out of the expansion tanks bleeder valve.
  • Wipe as necessary or let your pan catch it, your choice.
  • Once the bubbles stop, and it appears to be all coolant let it keep going……….for about one minute.
  • Then close off the bleeder screw, put the expansion tank cap on and you’re DONE……..!!!!!
  • The following morning check the coolant level and fill to appropriate level.
TIS says to:

1. Turn on ignition.
2. Set heating controller to maximum temperature.
3. Set fan to low setting. This opens the heating valves and starts the auxiliary water pump.
4. Perform filling operation slowly.
5. Pour coolant into coolant expansion tank up to max. cold fill level.
6. Close vent plug when bubble-free coolant emerges
7. Close coolant expansion tank.
