Adding Coolant
« on: June 23, 2018, 02:03:42 PM »
Did the test strips and the  result was to drain out 2 gallons and add 2 gallon of concentrate. My question  after I drain the two gallons from the radiator peacock,can I just pour in the concentrate,or do I have to seal the gap  around the radiator cap where I have the funnel in and run the engine until the regulators kick in and suck the coolant from the funnel.

Will probably sound flippant, but you will know when you try to add the 2 gallons.  Adding it slowly, if it all goes in, you are good to go.

If it doesn't all go in (same volume as you removed) then you will need to bleed the air from the system.  Many coaches have a line from thermostat housing to reservoir to do this automatically.

On my 1993 Foretravel with Caterpillar engine, I found that cracking open the coolant line to the air compressor at the thermostat housing was a great/easy way to bleed out the air.
