is this the little valve in the coolant filter housing? it looks like a lever.. If it's one i'm thinking of, I have a hook for my slide hammer to jerk it out of there then go back in with the new one once you look for debris like a piece of the old o-ring. to avoid draining the coolant, you can have a helper hold a shop -vac over the filler hole and apply suction to the tank. do not seal it to the tank, use youre hand to maintain a 1/2" space between the vac and the filler neck. when you pull the valve out, the vac will suck air into the hole rather than allow coolant to gush out. of course you will need to burp the system when its done.. just an option here,,, jojo

Awesome!!!

Too bad our King isn't concerned about our country's border's, like he is about Ukraine's Border... Jojo

That's the Damned truth !!!

Ox50,,,, Meet (FJH).... He always pull's out a good approach to a problem. From what I can see here, he take's the time to study the issue and then post some real smart sh!t.... jojo

the steel pipe from the compressor tends to build up with carbon and blocks the flow.. i bet its restricted.. you may be able to take it out and throw it in the firepit and burn it out, or just replace it.. its expensive, and hopefully still available.. lately, common parts are a bitch to get... jojo

I jut saw the truck again... Spoke wheels?? what country are you in? no biggie, just curious..

I forgot to ask about power steering performance in my last question..jojo

are you having issues with building good air pressure in the tanks and maintaining the pressure?

For Sure.... thanks Bob

I know I just said I was out.... I was wondering if the after treatment ECU is trying to read the 2 differential pressure systems? EGR/DPF? How do you 'lie' to them so they think they are doing a good job? jojo

ok... well to be honest, I know nothing about deletes other than they breed future problems.. with respect, I am backing out of this post... good luck sir, Jojo

you reckon.... programming is the issue? do you need a 'file' that supports the delete? I really don't know what the 'f' i'm asking here but it seem's to make sense.. jojo

that screen looks like Premium Tech Tool... there are calibration tasks in the program, I dont know about deletes, but do you still have a DEF system? or is this an '09 before DEF? to calibrate the VGT. you have to remove the accuator and run a calibration then install it to the turbo... (B.S.) there is also a gauge to check/set the 1/4 gear into position.. jojo

I drive an Isuzu NPR with a 16" box as my service truck. I love the maneuverability. However, I would love to have an MR with an E-7 or Early E-tech as my service truck.. It would be 'overbuilt' and that would suit me just fine..

we used to be ''mechanic's" but now we are parts changer's... all in the name of "quality control" I get it.. but I really think it's about "Income control"... it's funny how a 15 year Indonesian kid can build a component better than we can.. anyway, just a little rant on my part... jojo

there is a bunch of things that are sent out or just bought as a reman now.. jojo

Robert Bosch 8100... I beleive... I really wish that I worked in the pump room 20+ years ago, it is my only regret, during my Mack years... jojo

The RW I'm working on has an Ambach pump with the reversing relay and a Bimber valve.. I guess i'm robbing this thread for some knowledge, thanks again.. jojo

I was curious about the boost pressure that was posted.. I didnt think they made much more than 32 psi, but my knowledge is more about E-7 and E-Tech... Jojo

JoeH and Glenn... are you guys talking about the reversing relay screwed into the the intake manifold? I am working on a Superliner with an E-6 4valve, and I was wondering if I should replace the reversing relay.. I havent checked to see if I can get one yet... just curious, Jojo

ok... just because.... is the throttle lever loose or slipped out of adjustment? jojo

loosen 2-3 fuel lines at the head, and pump the hand primer until fuel comes out, wait for the air bubbles to stop. tighten the first line that bleeds, then pump again til another one bleeds, tighten it then go on to the next. (17mm or 19mm wrench) then fire it up !! jojo

they need to be their own country..

pic's ? please ?
