Its only obvious to those of us that work, and employ workers.... Oh yeah, and have to decide if they are going get a new.... anything.... or pray the old one hangs on for a bit while I fix the house, or the car.... Oh wait, keep my kids in good repair as well... Just my thoughts... I dont have kids, but I have the other things... Just a small working fish in a pond of welfare pirrahnas... Jojo

with the belt off the water pump, there wont be any flow, so the water will be "still" until combustion pressure enters the cooling system... no biggie, its a bit of work to do this test, but a heck of a lot less time than pulling heads that didnt need to be pulled, plus the cost of gaskets and bolts,, and whatever else decides to break..... Good luck sir, Jojo

Utterly amazing!!!

ok... I was told much less than 45 years ago that it can hurt the turbo.... thank you for clearing it up for me.... I have been laughed at a few times about this, guess I don't know what I think I know... 👍 jojo

is there a cap on the stack? if not.... tell him to check his turbo.... and .... yes .... girls kick ass......jojo

Holy Crap!!!! You Guys Just posted some real S#!T !!!! I just read back a bunch of post's.... and Hell Yeah!!! you guys post what I think everyday... I go to buy groceries, and see so much B.S...... .I was always told, to not judge a book by it's cover.... B.S.! it's very easy to judge now.......Thanks Barrack? and now we have you're Monkey... jojo

to me... a slight vibration on this engine, can be many things... what other things were done to the truck recently? I could ask a bunch of questions, but the list would be long... check the obvious things like loose bolts on the fan, , alt., a/c comp. a sloppy fan clutch, Take the belts off and run it a bit and see if it still vibrates.... if it does, look at the clutch bolts through the inspection hole in the bell housing for an issue... Does it stumble when you rev it up? Like I said... lot's of Q's...there is an S-Load of smart people here.... we'll get it..jojo

well, he just armed the Taliban with our great equiptment.... whats next? a bridge from, there. to here?? it blows my mind, how any, "real" American could allow and support the destruction of our great nation..... I'm lost..... Jojo

Yes.... I was taught this procedure years ago by a 65 year old grumpy, MF'r.... Take the belt off the engine, by-pass the water lines for the air compressor, pull the top radiator pipe off, remove the thermostat, and put the housing back on, leave the short hose on top of the thermostat housing, fill the cooling system til' the water is at the top of the thermo housung,... which leaves 4-6 inches of hose sticking up off of the thermo housing , which will give room to watch the water perculate, like a coffee pot, pretty quickly if there is a head/gasket issue....you can let it run for 30 minutes or more at idle without overheating it. and just watch for bubbles in the top rad. hose... compression leaks will show up early.. i did chase a series 60 detroit that took a long run time before proving there was a head issue. I diagnosed it, but did not repair it... anyway, Good luck..... jojo

When you replaced the water pump. Did you inspect the housing on the front of the engine for pitting/cavitation?.... This can cause air into the system, which can cause excessive pressure and push coolant.. However, I'm still curious about an issue with compression leaking into the cooling system. "V" has touched on this... jojo

I don't go to sites that I don't belong in... not a big deal..... I also don't go to Gay bars.... Why????? because they are not my type.... It's simple math, and nobody needs to dislike the other.... just go somewhere else, no-harm-no-foul... Jojo

Nice try..... Those of us that work and pay for Buttheads to live for free, disagree.. jojo

ok, I am not familiar with Austrailian Macks. Here in the U.S. a 2005 is an ASET... Yes, 10 PSI is correct for an E-Tech.. Im sorry I didnt have the answer for you. Good luck.... Jojo

16 psi. should be correct for the cap... jojo

SB215025, is a service buliten that may be what you are looking for,,, Make sure that it applies to you, since you are in Australia... Jojo

Here in N.C. theres an add for jobs in the medical insurance field that clearly says they need english and spanish speakers, and will train to certify them as agents.. no experience neccassary....... Hell, why the hell do i fix trucks... I speak a bit of spanish, and a little bit of American too.... I may just check this out. I will post more as I get the truth out of this.... Jojo

The air starter on this truck should have the same bolt pattern as a 42 MT Delco starter.. I suggest using a 39 MT because its lighter and has gear reduction and will crank with weak batteries.. the air starter should be an Ingersoll Rand tire gun without the long anvil.... so to make the conversion. you could attach a battery tray, and (2-3) 925 amp. group 31 batts. and a simple push button start system, and rock-and-roll... jojo

the EECU would need to be re-programmed...too bad we cant just add a little exhaust pipe to the EGR pipe and let it leave like the big exhaust pipe... Crazy thinking by me.... jojo

No Ether..... Check fuse 40 in the EPDM next to the steering column under the hood. If its good, take a good 12volt battery and connect the ground post to ground on the engine. and make a little jumper wire to force 12v to fuse 40 and see if it starts. If it starts up, replace the starter. Jojo

if you have an Ambach pump, they have a controller with a diode, I think on the firewall.... Did you run a hot wire with an aligator clip to the posts on the heads just to see if they work? Robert Bosch pumps have micro switches.... and no diode... (Glenn,) correct me if im wrong...

it may have an electronic control on the back side of the injection pump...(governor housing) easy to see., a round gray plug.. the 400 has a great power curve, and can pull anything that the other (non MACK) trucks can pull. That engine is the last of the Million Mile Engines..... with the exception of a well maintained E-Tech ......which came after that one... jojo

run time on an un-cooled compressor is short, before damage happens, however, youre post tells me that you have some good knowledge, and you will be cautious doing this test.... looking forward for the cure being posted.... jojo

I was so upset, I left off 2 'Zero's' Sorry... jojo

so they know who's not vaccinated in the U.S.,, around 90,000 is what I heard, but they didnt vaccinate the Arab's they flew here, and the border jumpers in the deep south, but If I am not vaccinated .... I can't get on a plane or eat a good meal, or whatever...... ... Please ... correct me if i'm wrong.... I have many issues with this, as do, you!!! this is bigger than I can understand... do I need to Armor one of my trucks and fortify it with stout guns??? Why the hell am I thinking this way?? I'm No wimp, but WTF?
