    what motor

    ASET 460hp if has egr cooler and Vgt turbo is an ASET commercial meaning a highway application engine. If it has a straight turbo, which if 2005 should be an ASET AC, will be a ccrs type etech, most likely the AC. As joe suggested, look on the front v/c and data plate reveals all.
  2. Is the shutdown lamp coming on? Red circle with an X in middle, when it does it and may want to make sure it works. Usually 3 Amin shutdown causes are oil pressure, coolant level and temp if turned on. Have seen oil pressure sensors cause the problems and with an rd, the gauge is mechanical with an extra oil psi sensor for the ecm, located on top or side of oil filter housing or stand. What you can try is, unplug the oil psi sensor when it starts to do this, changes the code from a mechanical problem to an electrical and will cause a shut down, but most of the time it will run for awhile. Also, if male lamp comes on and you can catch it when your not driving, flash code by turning cruise on/off switch off and pushing the set down then up and count how many flashes. Maybe that will help figure out problem for you
  3. Also, if, just on the off chance, you pulled the “y” hose from bottom of the pancake oil cooler, they use a screen inside of it and when you removed and didn’t find that screen, it may have gotten in the lower pipe and could cause same effect as the rag issue. Something else to think about. Small possibility that and if you put it back, the rear water line to air compressor from the back corner of the block could have some blockage due to casing materials. Mackpro can attest to that I sure. There is an old bulletin on it and correction is to move the back water line from corner of block around to the water manifold. Also, had one that did similar and ended up finding that the water line from the water pump to compressor had pin holes, sucking air in and had collapsed near the fitting at the water pump. Maybe something else to think on
  4. Just want to show another titan at work and why yes, that is my service truck in front of it!!! Lol. That is a 2007 titan and was carrying a drill to cape canveral a few years ago. I do love playing with my puppy dogs!!!!!

    Mass flow - open circuit. It’s that pipe on drivers side that has the 2 sensors sticking up in between the two rubber hoses. If its bad, most likely the temp sensor inside was hit by moisture, ie, water. If you are not loosing coolant, then most likely was condensation which builds up in egr system after it has been ran all day and sits all night. If on the off chance you are loosing coolant and you don’t have any external leaks and can’t find where coolant is going, very possible your egr cooler is starting to leak internally. If you replace the mass flow assembly, pipe with the sensors and it’s small ecm, look and see if the “liquid “ inside is is clear or coolant colored and go from there. There are other reasons for it to code an open circuit, but that is the most common cause. Most of the time, you can run it with the code and it not effect engine op but it can cause odd power issues and even cause the turbo to go stupid intermittently. And before asking, it is an assembly and unless someone that I haven’t heard of yet has done it, you can’t change the sensors, they are welded to the pipe and that pain in the butt lil ecm and sensor are programmed together. Hope that helps
  6. There are lots of places that claim they can do it and I know it can be done, pain is keeping up with whom ever does it to begin with. Check for around northern end of Florida ,( somewhere around the Jacksonville area and can be found , if googled correctly)and that’s as much as I can say due to the fact that , first , I work for one of those “crappy” dealers you referenced and due to that , I have to limit saying whom, because, I like my job which pays my bills and bosses like to look for ways to slap you around. But I was never hear and didn’t say anything but to tell you that it’s against the law to mess with Mother Nature!!!! ( also maybe a name starting with something like, uuiummmm, southern diag) oooppps, I didn’t say that out loud!!!!😱🤭🤫
  7. Another of my 2 cents for y’all. One of y’all are gonna come and beat me up for getting in y’alls conversations, but here goes on the 460- change it to a 427 hp- (I hear this coming) if you will look at torque spec sheets for 460, you will notice that it doesn’t start to really go up until almost 1600 and around 1680-1700ist it drops, straight down. The pain with the etech programming has been, the lower hP, the longer the torque stays up. Something to think about. Also, I didn’t read deeply into the comments about pyrometer reading high, if it is and you notice coolant temp going up in a hard pull but seems ok most other times, look at your exhaust manifold and turbo exhaust housing, if they have a “velvet” appearance, it is a boost leak and if guys have checked your intake system and say nothing is wrong, ask if was checked with test plumbing on the turbo inlet or just checked the inner cooler/cac/air to air. If only cac was checked , check it plumbed at the inlet of the turbo and this is where y’all are ALL gonna think I don’t know the per per verbeial but from a hole in the ground, done heard it. If everything is sealed on your intake and I also mean the air compressor inlet, which comes from the back of the intake manifold to compressor, pull the outlet line from the air compressor with pressure on the intake system and see if you have air leaking. Just had to put a compressor on a ‘99 and customer thought I had lost my ever loven mind until we hit the first hill with 92,000 on, not the first one I ever seen. Y’all can throw the tomatoes toward Alabama and NO, I ain’t no damn football fan. Good luck and sorry if I disturbed y’all
  8. There was a company in Tyler, tx that was repairing vmac ecms and I can’t find number on line now but showing in eBay several m7 modules. Also an option, possible slim one, is check with DEX used parts, this is the Volvo/Mack used parts department. You can find them( I have 2 vmac 2 ecms and nope, don’t ask, one has an rpm issue around 1700, thanks Nick, and the other is my bestest test ecm, sorry) at several bone yards and such. Check with tony at Turbys used truck parts in vina,al. He didn’t have one a week ago but he gets trucks in all the time. Just tell him a Martian sent you.
  9. Just a stupid question..... WHY??? And when you are talking about a big bore, Cat, Cummins, Detroit??? Unless it was ordered with an MP 7, which it probably has an MP 8, the engine compartment is being squished with the 8 due to engine length and that lovely sloped hood. Truth be told, it could handle an ISX and that’s is crammed. I would love to have seen the cxu chassis with stretched hood and an MP 10 shoved in there, oooo the capabilities, lol!!! Good ole 3406 would be rear purty too, but that went with those beautiful super liners. Just had to go an pitch 2 more cents in the pile! Have a good time with it.
  10. Gotcha and by the way, the wastegate part number you want is 172743. If the one you found online is the 171702 p/n, that is a non waste gate turbo. Get your vecu to 12b , 380P4 , which is for throttle response, won’t do anything for engine power but does help somewhat with tps reaction and if the person that is doing the programming is an older Mack “mechanic “, ask him if he knows Mr. Frank in tech support, if so, he might be able to get them to change the engine files as well. ( I didn’t say that out loud) good luck and keep me posted, just curious on how it helps.
  11. As mackpro asked, what’s trans? If manual, possibly switch installed in air line to pto, if Allison , please correct me if I’m wrong, Mackp, then pto signal is controlled to vehicle ecu by trans ecu.
  12. Wondering where you work, you sound as bad as me about mp’s lol , 

    birmingham,al and that’s all I’ll say for the moment 

    1. Mackpro

      Mackpro

      Live in western Kentucky,  around Paducah. Working for a company with a fleet of fairly new Mack’s for about 4 months now. Before this I worked at a Mack dealership for about  30 years. I started there in 1988. 

  13. I agree with Mackpro, even though, I sure do miss a 427 Vmac 2 setup, damn those are fun!!! lol
  14. 305mack is one I’m asking about model, etc
  15. Yep, need to know how sensor is done and on the second truck question, not Mackpros answer, what model and all do you have, different years, models, makes a difference.
  16. Oh, look on your valve covers to find out engine model/hp stuff
  17. Look on right frame rail, possible just behind shock and on top of rail and if no vin number there Ieft rail, same area. Vins are stamped into one or other frame rail, just so if someone stole the door, lol. You will play havoc trying to find out info by engine serial number
  18. Yes, check the orings, especially the one you see fuel coming from line, if they haven’t been out since, well, a long time ( sorry,me being a S/A) then pull all of them and reseal, change your oil afterwords and watch it, still does it, check transfer pump and then have someone, ie, pump shop, check the injection pump. You will probably find issue at that one injector. So you know, injectors torque at 45 ft lb
  19. Starting in 2015-6 is when the OBD2 connector was put into the trucks, before was 9 pin all way back to 99-2000. Note on obd, Volvo, desided to be different and the iso wires are not in same places as all other brands. If using a serial link, tell your customer to make sure the order the obd connector for volvo/Mack
  20. Hope you have it fixed by now, if not and you see this, please answer back and I will check the code. If what I think it is, it has to do with the dosing system of your def fluid,but since I’m curious now, will look code up tomorrow and try to put and answer back in, sorry I’m not a computer and I can’t remember all of the code numbers since they keep changing
  21. That is S 004- fmi 14, which is the left rear( I think left ) wheel speed sensor. If it’s intermittent, quite probable your have a loose wheel nut and allowing hub to move in and out just enough to cause code, check your torque on the wheel nut(s) and might want to pull drum off and check the sensor adjustment, anytime you do brakes, always push the wheel sensors against the tone wheels while you have drums off
  22. If you have ‘09, on your dash, if you have the “basic dash” it will have a small button just below odo, if you have the arm to the right of steering wheel, upgrades dash. To read codes, basic dash(pain in the ass) you have to catch odo reading actual and mash lil black button and hold till dash changes to showing(hopefully) m128, then below write all other numbers down, with “stalk” switch, navigate to diagnostics and you can read codes in there. If you are getting the red circle/X, that’s the shutdown lamp and the 3 main causes and are settings in parameters, are coolant level, oil pressure and coolant temp. By your description, sounds like you possibly have an oil pressure sensor reading low at idle, if it’s an MP7, sensor is located at the front of the oil filter stand, just above the front bypass filter, MP8, oil pressure sensor is located drivers side, to right of engine Ecu and is the top sensor, bottom is crankcase psi sensor, which can cause shutdown, but most of the time when ccs sensor is cause, it will shutdown anytime. Hope that helps
  23. Will check with my fend that did most of the work on kitty kitty,but I do believe the 171702 p/n is correct
  24. Since it’s an AMI, yes sir and will(if you haven’t already) mount up with no problems, make sure the waste gate works and please let me know how it does with your 370 hp,please, oh please!!!! I know of some ASET AC engines that have been changed a slight bit and that turbo was used, on one perticular one who had been getting passed by a KW CAT3406, the comment that he sent to my buddy in a text was “ HERE KITTY,KITTY !!!!” You may not have the same results as him,but it should help a pretty good bit!!! Good luck
  25. Well, for the sake of sounding like the smart ass that I am,sorry, if your working on a 2000 model, that would be an ETech engine and depending on what part of the year it was built, may be a “CCRS”. If her has the uprite thermostat housing, outlet going straight up,takes 1 thermostat and by all means,please put the weep hole to the top, even if you pull old one out and it’s at the bottom or somewhere else. I saw a comment about using scalstic, only if you like digging it out of small fittings and hoses and you do t use the gasket that comes in the new thermostat kit, which, make sure if gasket does cover the check valve(hope it’s a Mack brand) cut hole out and put a new oring in there. E-7 (90-97/8) is done same way. Just thought I would chunk my two cents in the pot!!!!
