flatbed56 Posted September 1, 2010 Share Posted September 1, 2010 I flushed my coolant and let it run till clear, then let it drain. When i add coolant it so far only took 4.5 gal. I drove it around and checked when I got home and only added a quart. Did I do something wrong or do I have an air pocket...thanks Link to comment Share on other sites More sharing options...
Owner Mopar1973Man Posted September 1, 2010 Owner Share Posted September 1, 2010 Most likely didn't drain out the block very well it can hold a extra 1.5 to 2 gallons of water if just sitting flat ground. When I drain mine out I either jack up the rear of the truck or back it up a steep bank. Link to comment Share on other sites More sharing options...
Staff AH64ID Posted September 1, 2010 Staff Share Posted September 1, 2010 Exactly as Mike said, the block holds a lot of coolant, over 2 gallons on mine. Because of this I would do 3-4 flushes before adding coolant. Add the concentrate first, and use enough for the half the full volume, then top it off with distilled water and you will be at 50:50.

If your in florida or some southern state I would most likely let it slide and just top off with straight coolant... But Idaho I know gets cold so yea its a good idea to re-do it...
