Thank you all, so I guess I'll remove them. Very interesting info

My M1152 has these all around, Friend thinks it some kind of RFID

Not my humvee, came out of one I was working on. Military alt failed, swapped in civi alt, test run civi was not charging batteries so trouble shooting found bad start box and 7 out of 8 glow plugs bad. Put good start box in and alt was charging as it should. She put up a good fight.

Latest update, went on 20 mile test drive, speeds up to 55, temp never went above the little "flag" (temp symbol) on gauge, fan kicked on and off normally. Very happy now. Action I owe you a case of your favorite beverage :)

Thank you, I figured $50 in product was worth it vs $500 for new shroud.

Update. 10 mile test drive so far so good, temp only went to mid green, fan kicked on around 220ish hard to read on mil gauge. Shroud repaired.

So today I installed the correct fan on my 1152, ran her at about 1000 rpm for 40 min, temp went to mid green, tomorrow a test drive and we'll see if she got any better, next I'll fix the shroud.

Yes, V belts on my 998

I'll update post when fan arrives and if that did in fact solve the issue. Ordered OEM fan from Midwest, very helpful company with fast shipping.

DING DING DING Action wins with the wrong fan comment. I compared my 1152 6.5 TD to my 998 6.5 NA my 998 and my 1152 have the same fan installed. The 1152 has the 6.5 TD with surp belt and if I understand correctly the water pump turns the other way so fan blades should be opposite. The USMC...

Oil looks good, not milky, oil fill cap is clean, no white smoke out exhaust, no blow by (that I can see), runs good, sounds good, just overheats.

I did remove the thermostat but did not drive it. I have tried the original thermostat (it was bad), tried civi thermostat that I tested before install (later removed), currently installed is an OEM thermostat. I am leaning toward new radiator, can I have a leaking head gasket and it not show...

Thanks Mog, is that part number the same for my ECV model (M1152). I’ll look in parts book later. Thanks

Thanks all, next is pull the radiator, I found a shop that sounds good for cleaning out radiator, I’ll go by and talk to them and make sure that can do it. I plan on putting Fleet antifreeze in after I get it working. I tried the radiator cap off my M998 and no difference, still gets hot...

Old coolant looked light green, in my post #1 i mentioned I did an eng block test, that was for exhaust gasses in the coolant system, the test liquid remained blue, Just to test the liquid I placed it in the exhaust and pumped the bulb, the blue turned greenish yellow. I do get some bubbles...

I took the original thermostat out and it still heated up, tested original thermostat, bad, I installed a civi thermostat and it heated up so I then installed an OEM thermostat same issue, I removed the upper hose and started engine to check flow, granted I do not know what normal flow looks...

I feel air blowing, but I'll double check. Thanks

Need help figuring this out, my 2006 M1152ECV 6.5 Turbo gets hot when I drive, sitting in drive way I can let her run for hours no issue. So what I've done so far; Changed all hoses, new surp belt, new OEM thermostat, flushed radiator, fresh antifreeze mixed to 50/50, preformed eng block test...

Thanks 86, sending a PM

Anybody have this before ? The brake light switch in my M1152 (left side) gets really hot. I don't see a test procedure for the switch in the tm's, I can't imagine it's supposed to get hot. Also I believe the right side is brake light what is the left side ? I think I remember reading it has...
