HELP GUYS OR SUGGESTIONS

What is SS LINE??

 

Stainless steel line that comes off the compressor, it is a flexible line.

 

Thanks, I need to do this egr was changed no fix still having heavy bubbles flowing into bottle with overflow line in it, going to do a gas test on Thursday when truck is done for spring bushings, also going to replace both caps so hoping I don’t end up needing an in frame dd15 650k miles no chance of damaging air compressor doing this ??

 

Also dont see signs of coolant in oil, system - coolant Sys pressure has been causing coolant loss out overflow line just hooked up bottle before putting in shop for bushings, will know more Thursday after gas test n caps

 

Also not over heating 180~200

 

A few minutes won’t hurt it. Worst thing could happen is warping compressor head or gasket. You’d have to run it a long time for that. Hook up the bottle test, Start Truck, note how long till bubbles appear. Shut Truck off, crimp or loop both coolant hoses to compressor, and unhook SS air line from top. Start Truck, check bubbles. Same? It’s not compressor. A Within a minute you’ll know, Won’t hurt it. Next check oil. Take return drain line off turbo. Start Truck, check bubbles. Same? Turbos not the problem. Only other cause could be a air controlled heater valve. Depending on your Truck make. You can tell if your cab or bunk valve has a small airline going to either or both. If so, turn off all 4 water valves under hood. Check for bubbles. Same? Probably have a cracked head, blown gasket, or dropped liner.

 

Forget the turbo test, my bad. Turbo test is for blow by, nothing to do with coolant.

 

Noticed last week I had heat but not as much,,

 

My last trip home this time last year it had turned cold. Had to stop twice and let it idle to get heat. Topping coolant didn’t help, it just blew it out. I thought it might be pushing coolant. Ran a 2500 round anyways. Finally did a bubble test, 1000 miles from home. Barely made it home. Lol. Last Truck blew head gasket at 540k. First sign was heat loss, then noticed coolant spitting out. Replaced thermostats, had shop replace Waterpump. They were right, head gasket. Ended up with new head. At 825 it blew again. Motor hydro locked. Cylinder liner dropped. Had it inframed. You may have to decide whether to do an inframe now, while it’s apart. Might just need a gasket, maybe gasket and head. Might have a dropped liner. If so, an inframe kit for sure. Not worth it to fix just one cylinder.
