Egr hose

Well the Egr hose split on me yesterday. Its the tiny one that sits in the center of the engine. My question is can I just get some radiator hose and cut to length. Does anybody know the size? Please help me out, hate it when my truck sits...lol

If your talking about the coolant lines to the EGR any 5/8" heater hose will work.

If you still have the EGR cooler good luck using bulk hose and bending without kinking it, NAPA has the pre-formed hoses.

Any 5/8" hose will work, don't need a pre-bent one. Its a straight shot, make sure it's cut to the correct length and you won't have any issues. Had mine blow out too, made quite the mess. While you are replacing, you should swap out the O-Ring on the thermostat bypass to the EGR cooler, they tend to get brittle with age.

Straight shot IF you have the cooler removed or have bypassed it, the two letter word "IF" over looked, a lot......

Its a slight upwards shot with the cooler in place. 5/8" radiator hose is flexible enough not to kink. Had to replace this hose before my egr suddenly fell off.

Would that be the o-ring (110) in the diagram above. What kind of pliers did you use to get those clamps off? The one I can probably get to but the other looks like a pain. Im going to start to take it off this afternoon.

Lol gotta love your persistence. Its a 2" long 5/8" radiator hose. It will be fine.

I used small channel locks to get them off. Replace them with some worm clamps
