Title: Radiator tank leak 2001 U320
Post by: dsd on June 03, 2021, 10:28:43 am
So after my last 2k trip I noticed I was down on coolant and the aft tank is got a small leak. I've read were people have snugged the tank bolts up and resolved there problem. I know what I currently have and am concerned of opening Pandora's box on the road. I prefer not to use stop leak because I just replace all the coolant and would rather just repair once home.
My two questions are
1 Should I adjust the tank bolts back up to torque?  Or just relax and keep filled
2 Does anyone have the gasket part numbers and possibly a source to order them from so when I get home they will be waiting for me.
My initial inspection shows nothing to be falling apart or corroded and I have zero cooling issues, however I was not surprised to see this accrue do to increasing overall operating temperature and pressures. Coach has been running at 183 degrees going down the road. Never exceeds . Prior was running 160s . Once apart this may be viewed differently.

You changed cooling fan speed too, as I recall.  160s is low, mine normally runs at 178.  Very hot days, grades mid 180s, maybe a bit more.  What are the torque specs?

5/16 bolt probably not much. Torque wrench in Nevada so I would just pull up by hand. Just don't want the gasket to split and cause a real leak

Scott, if you just replaced the coolant you probably also drained the Bar's Leak. There was a recommendation to put Bar's Leak in the system even if it wasn't leaking. I think it was even a Foretravel notice. I added the Bar's leak after reading about it on the Forum. I had a small leak also and it is now stopped. The biggest problem was having to siphon some coolant out of the tank to make room for the sealer then having to put the Bar's Leak in and driving the coach to get it hot enough for it to work. If I was on a trip it would have been easier than doing at home.

Scott, Personally I would just keep an eye on overflow tank and keep it filled to half way, then enjoy the trip
Chris
PS I always keep at least 1 gallon of antifreeze mix in the coach

Scott, that is the same area mine had a leak for a few days right here in the driveway. It stopped leaking and I wasn't sure what to think. I had been told the radiator had been replaced by the PO. I'm interested in the Bars Leak TSB from Foretravel. Craneman thanks for the tip, did they give a recommended amount? would really like to add. Getting ready to change out all hoses, clamps, t-stat, and coolant. Thanks, Jim.

Scott how long did was the coach parked there for that much coolant to
drop there. I would probably try and very carefully try and tightened the
bolts, I have done it before in heavy equipment with good luck. They were
cork gaskets. You would have a better idea as you are there.

Left Boulder with two gallons oil, two gallons premixed anti freeze, small funnel, and quart coolant bottle for transfer bottle. Added about 3 qts. Probably overthinking it. Last trip home I was filling with a gallon jug with potable water every hundred miles. PITA. I'll pick up some Bars leak and add to tank. Jim said it was one dose per four gallons. I figured it would take a year to work out most of the bugs, in month eleven now, got to be getting close.
Thanks for the help
Scott

Really wasn't leaking much over night as much as residual from on the road I think. Was parked 12 hours. Added one bottle per four gallons. 4 bottles total

So although I've never been a fan of the bars leak I installed the recommended bottle per four gallons and last 200 miles didn't loose a drop.

My 03 leaked from end of radiator as well.  I snugged up the bolts and wasn't leaking when I sold the coach about 3 to 4 years later.  FWIW

Well we finished our week long 4500 mile wedding trip and the last half was leak free. We did loose the left rear hub cap and nut covers and a engine hood latch striker pin was liberated from the coach in the last 1000 miles. Glade I wasn't working on a leak anymore.

What is the engine hood latch striker pin?

That little headless pin that all the doors latch onto. I'll make some up
