I recently replaced the radiator and not sure if the coolant was bleed properly. The heat seems to be okay, but just wanted to make sure. So what is the proper procedure to bleed the system and make sure the radiator overflow hose is full so it will suck it back in from the overflow reservoir.

Thanks

 

from service manual.....

STANDARD PROCEDURE - COOLING SYSTEM FILLING
Remove radiator pressure cap (Cooling System Service Locations) and fill system, using a 50/50 mix of Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula and distilled water.

Continue filling system until full. Be careful not to spill coolant on drive belts or the generator.

Fill coolant recovery/reserve container (Cooling System Service Locations) to at least the MAX mark with 50/50 solution. It may be necessary to add coolant to the recovery/reserve container after three or four warm up/cool down cycles to maintain coolant level between the MAX and MIN mark. This will allow trapped air to be removed from the system.

 

What I do is fill the system and then start the engine. I wedge something in the throttle to hold it up around 2k rpm and run it until the thermostat opens and the fans run. I have a funnel that connects to the radiator fill so the coolant doesn't make a mess when it expands and the air bubbles out. After the fan kicks on the second time, I wait until the coolant level goes down and then put the cap on. Remove the item holding the throttle open and fill the overflow. Any other air will make it's way out on it's own after that.

Or you can buy a sweet vacuum filler. I bought one about a month ago and don't know how I lived without it. Fill a cooling system in about 2 minutes, no air pocket, nothing, just fill and go. So nice, but a little expensive for the do it yourselfer, $150 or so.

 

I've done it 6-7 times on mine and other caravans with and without rear heater pretty much like Tizzy1's method. No problems. Just check it after a drive or two and top the reservoir off if needed.
