I've got a 2006 quad cab 4x4, 83,000 fairly easy miles. I noticed a small puddle under the engine last night, coolant leak. It's coming from a small rubber hose on the passenger rear side of engine. Looks like it attaches to hard line that goes into the heater core.

My truck will be 10 years old in February, but has low miles. I tightened the clamp down on the hose, it was fairly loose, doesn't look like it's leaking anymore. But it must have been weeping for a while because there is no coolant in my recovery tank. I'll need to add some more to bring it up to proper level.

I know I should probably change the coolant out. I think I will drain it as much as I can and refill with the proper coolant. Should I do anything else while I have the coolant drained? Should I change any hoses or are there any other trouble areas?

Thanks.

Looks like from past posts, Dodge has a replacement hose and clamp kit for this part. I'll go ahead and get that and take care of it, though I'm still searching for the part number(s) for that.

Any opinion if I should do anything else while I drain the coolant? Thanks.

I just tighten my clamp whenever it starts to drip, been 3 times in 127K miles.

Very known issue on the 06 as you have discovered.

I snugged the clamps on mine a couple of times and it has been fine.

The updates hose I believe comes with spring type hose clamps.

If tightening it stops the leak I wouldn't worry about it, or I'd wait until I need to flush and replace coolant to change the hose.

If I was going to service my cooling system, I would replace the thermostat while I had the system open. They don't last forever and replacing it now can prevent problems down the road. I'd use OEM from Cummins or Dodge, I haven't had good luck with aftermarket thermostats in these engines.

you are going to change the coolant, replacing the hose would be worth while. If you aren't, wait until you do and have time to spend. Changing the hose is a royal PIA.

Did you get the part number for that kit? I'm looking for the same thing.

Yep, I've had to tightened mine a couple of times since new. Now at 11200mi. kind of hard to get to though. It's the little hose kinda behind the turbo.

It stops leaking when you replace it w the new orange hose and snap rings.

Did mine back in '09 or '10 and is still dry through the 6-7years of winters and temperature cycling.

What is the product number or description I need to search for to get the new kit?
