International HT570 diesel engine

[Hay Dude]

Looking at buying a truck in NY with an IH HT570 9.5L diesel engine.
It’s an ‘07, so it’s a pre-emissions model.

I have had a few trucks with DT466’s and DT530’s in them. They were stout. Don’t know the bigger ”high torque” HT-570.

Heard all the horror stories on the ”Max Force” versions, so not even going there unless I would get a great deal.

Its a 7/06 engine build date and its 310HP/1050TQ.

Do a bit of homework. Tractors got real serious about emissions in 2014. Trucks started about 2004, I believe. My 2008 Dodge had a diesel particulate filter and some kind of exhaust gas recirculation. That was the first year for that particular engine - always a bad thing.

I never saw any emissions on a truck dated 2007MY or older, other than EGRs.

I never saw any emissions on a truck dated 2007MY or older, other than EGRs.

"To achieve the 2004 emissions, most manufacturers introduced exhaust gas recirculation (EGR)—in many cases in conjunction with diesel oxidation catalysts—on heavy-duty diesel engines."

Good information here on HD diesel emissions.

The International CEO nearly bankrupted the company wth his "EGR only" emission goal, while his engineers said that it would defy the laws of physics.

I am not really into on-road emissions, but i read its the emission standards that were implemented between 2007 and 2010 that allmost bankrupted the company due to warranty claims, loss of business, and non-compliance penalties.

Because Navistar International was late to the party and had to pay non-compliance penalties, i suspect the 2007 model didnt have this troublesome emission system yet.

With offroad engines, on the manufacturers plate it is stated which emission level it complies to. I dont know if on-road is the same, or if emissions are approved as a whole truck, instead of an OEM engine like we used back in the day.

Oh by the way: if that engine is buit 07 month, 06 year, it means that they have buffered the MY 06 engines for use in 07 so they didnt have to pay the non-compliance fee yet. That would mean that youre good with this engine...

Excellent, because I’m very close to owning it. I don’t see any emissions hardware on it, so I was pretty confident.

I used to work for an International dealer as a mechanic, those are a fine truck engine. They had EGR and a catalyst muffler which could easily be removed in favor of a normal muffler. Most frequent problems are injector harnesses and leaks in the high pressure oil system. Just don't buy the next model year.

I have been looking for about a year and purposely avoiding the “Maxxforce” engines.

Update on this engine. I have been operating it for about 3 years now. I had to replace the head gasket (pressurizing coolant system), radiator (was pretty well shot) and exhaust manifold gasket (popping sound under acceleration) along with all associated hardware (turbo gaskets, head bolts, etc.) Truck runs excellent and pulls very strong (310HP/1150TQ)

However, I seem to have another “problem”. Both the engine and transmission are heating up pretty good, especially under load. After about 30 minutes of running, the truck’s temp gauge will hit 210 and the big fan kicks on. This cools the engine down rapidly, but the cycle continues as you drive and it doesn’t seem “right” to me.

An IH technician I know thinks the trucks ECM does this on purpose to “burn off the EGR cooler”. He may have a point there, but heat is so bad for equipment that it seems like the truck would be destroying itself. It has never overheated, but the only thing saving it is the big cooling fan.

The Allison transmission temp gauge also hits 200+ while operating. I do know the transmission is cooled by the radiator stack, so that could be why the transmission runs hot.

I feel like this is abnormal and shouldn’t be happening. Me and the local guys are kind of baffled by this.

It could be the other way around, the transmission might be heating the cooling system.
