Hi guys.After having no heat for last few weeks I was thinking of ordering a heater core,but decided to flush it first.Still no difference.Figured the pump wasnt pushing enough volume through the core,but truck didnt overheat.Finally I split the heater return hose and drained everything out and reconnected it.Then I used my buddies lisle cooling system funnel for refilling.Sits on top of rad neck and holds coolant.Wasnt real impressed at first until I blipped the throttle and saw bubbles.After about 15 minutes of revving up engineand letting the coolant percolate I checked the cab.WHAT a difference.I had to turn the dial down on the ride home because I was sweating.THATS never happened before.Usually I am sucking down hot coffee so I dont catch a cold.Hard to believe I had that big an airlock.Anyway,the tool is cheap,less than $20,and is available on tool trucks.An air evac system would probably work better but thats about $120.I think if your working on a ram radiator this tool is essential to keep your sanity and your juevos warm.Hope this helps somebody,as I have learned a lot from you guys.

 

Please post up a pic of said tool.

 

Sorry left it at work,but its a lisle 24610.A bargain at twice the price.

 

I am really baffled by how you used it and what you did. You said, "I split the heater return hose and drained everything out and reconnected it.Then I used my buddies lisle cooling system funnel for refilling." I don't understand how this tool works. Also, where did you purchase it?

 

OK.Allow me to reiterate.I split the supply line of the heater hose{off of the water pump}.Apparently my air lock originated there.I installed a flushing tee in that line to alleviate further air locks,although a bleeder valve would be better.After installing the tee I installed the t cap loosely.Then I put the funnel in the radiator neck and filled with coolant.After coolant began coming out of the t,I closed the cap.Then I filled the funnel up with a/f and cranked up the engine.After a few minutes of running to warm up,I started snapping the throttle open.Every time I revved up the engine I would get bubbles.After about 10 minutes of snapping the throttle I let it idle for awhile.When I got in the truck it was toasty.Quick fix and better yet,cheap.Any good tool truck should have this tool,or the almighty ebay.

 

Ahhhh, a bleeder "T". Gotcha.

 

I did a web search and found this info. Looks like a BIG funnel that screws onto the radiator fill neck and has a valve at the outlet. See this link:

Yup I knew what you were talking about. We used to have those when I worked at a shop.

 

So what you are saying is that you added a 'T' on the return line. The line that goes into the water pump not the line that comes out of the block next to the thermostat? You then just used this big funnel to store coolant as you bled the air out of line. Did you do this while the engine was running? I really don't see the value in the $30 big funnel. I think the value is that you added the bleeder. Can you post a picture of your bleeder "T"?

 

The t is just from a prestone flush kit.It helps get a some of the trapped air in the sytem out,but not as much as the funnel.The most important part is to keep the funnel full and constantly snap the throttle while the engine is running.The funnel gives the cooling system a high point to burp,while allowing coolant to replace the air.I tried it without the funnel first and got little improvement.After using the funnel for 15 minutes I am convinced.I was a little skeptical at first myself,but now I have to turn my heat down while driving around town.Thats never happened before.Hope this helps
