GEEEE!
we haven't have the truck for even 1/2 year and there is an issue on the same spot twice.....coincidence or a particular symptom?

Anyways, at the beginning was the bleeding screw, got the brass one and now the T itself cracked right where the bleeding screw goes...

Again, is this a symptom? like a faulty thermostat?

will post some pics soon

 

here it is...

 

That T is brittle, plastic, crap. Mine disintegrated, too.

I made a new T with pipe fittings at Lowes. Metal.

 

You just change the tee/hose assy in January didn't you? Did you ever do the thermostat change on it?

Those tees generally take years for the plastic to deteriorate even when subjected to serious overheating and doubt your thermostat would be the cause. Possible different expansion rate of brass screw could cause a crack? Never heard of that happening and unlikely unless you just received a defective part from LR. No issues yet with my brass screw and carefully inspected hose junctions.

you really need to update every hose and hose assembly on your truck. When one of them goes, the next is sure to follow. Needs coolant flushed well and refill with green ethylene. Get a new heavy duty fan clutch, 180 Tstat, everything. An aging cooling system on a D2 will be the death of the vehicle. Weakest link on the truck and will absolutely lead to catastrophic failure. The plastic lines get replaced with new tubing and possibly radiator too. One of them is from the outlet of manifold so you will have to remove some accessories to get at it but all of this is required for dependability. Don't skimp on anything!

 

If you replaced only the screw and not the whole unit then it was just a matter of time. If the hose assembly is new then could be defective or screw was torqued too much. Can't tell you but def check everything else out

 

Had that problem too. Stinkin' plastic. I got a copper "T" from the hardware store, a big bolt, an O ring and a butterfly nut and made a metal fitting. Same functionality for bleeding, but it's metal and I haven't had a problem since. Inexpensive permanent fix.

I flared the openings and coated them with indian head gasket shellac to make sure the hoses wouldn't just pop off under pressure.

I can post some photos if you're interested.

 

Please do.

 

Yes please!

 

I did the same thing
But I never put in a bleeder screw...
