I think now we're supposed to be able to use DX to retrieve past work information, even if it's not at our dealer. The latest techcast mentioned this but I haven't tried it. PM me or Hino123 your VIN.

I'd take it to a dealer, for one. I'd ask for a printout of everything saved in the ECU. Then if there are tests they can do on injectors/turbo/whatever, you can ask for those results. I work on Hinos. I can go into the various ECUs and compile a big report showing all of the ECU...

Now's the last year to buy a ten year old straight truck not originally equipped with a DPF All diesel straight trucks got DPFs in 2008. Sent from my XT1585 using EO Forums mobile app

Every day.

Wouldn't it make sense to take the truck to someone who is intimately familiar with that brand and model? I'm a mechanic. A customer showed up with a 2 year old truck that he'd just bought, and wanted us to check it out before it hit the road. I wish so much that he'd brought it to us...

Which engine? Depending on the metering device, the lines will be routed like this: High side: compressor to condenser to reciever/dryer to expansion valve. A huge pressure drop across the expansion valve signals the start of the low side, with refrigerant immediately entering the...

That doesn't sound quite as bad, factoring for pizza.

P1459 suggests failure of the EGR valve. You can try a few things. Take the valve apart, clean it up, and reinstall. You can check that it has battery voltage, a GOOD ground connection, CANH and CANL at the EGR valve connector. Chances are good that the valve just died. Individual parts are...

Hino123, How do you manage a head gasket in that time? I rarely get stuck doing much actual wrenching, so my times are abysmal. Luckily I don't get paid flat rate. I'd much rather chase wires. I like getting the trucks that another shop has torn to pieces and thrown all the parts in a pile...

Knees crunchy as granola. Awesome.

What year truck? What else was done at time of DPF replacement? The DPFs don't fail by themselves, something else takes it out. There are several causes of this graph jump. Engine software, injector failure, impending turbocharger failure, intercooler blockage, etc, etc. Sent from my XT1585...

Also, blower motors have a finite lifespan. When they start using more juice, the blower switch, blower motor resistor, and various connectors are all susceptible to meltdown. Sent from my XT1585 using EO Forums mobile app

For janky heaters, you'll have to ensure that the cabin air filter (if equipped) and heater core fins are cleaned regularly. You may have to remove the core and blow it out/replace it if it's really bad. Depending on the construction of the heater core, previous mixing of incompatible...

The thing about retrofitting LED lights in a dash cluster is that you're not going to have linear dimming with the dimmer rheostat. But the FL70 will probably never suffer from gauges that are too bright. I doubt there is any aftermarket parts for this. You may even have to graft LEDs to the...

The issue with doing this yourself is occasionally one of the studs on the turbo or exhaust manifold breaks off, and they're a real treat to remove. Sent from my XT1585 using EO Forums mobile app

That is in an area that does not have common leak sources. I'm assuming that's road salt. The passenger side of the engine is where the action is. External head gasket leaks and oil cooler leaks are both common. Sent from my XT1585 using EO Forums mobile app

I think your fan clutch is acting properly. Sent from my XT1585 using EO Forums mobile app

Do you hear the fan clutch engage at all? It will roar. When it's not engaged, it will spin freely. This is probably unrelated to your coolant level issue. Sent from my XT1585 using EO Forums mobile app
