This kit will allow you to upgrade your International 4200 engine oil cooler from the problematic OEM style to our reliable and capable Air to Oil engine oil cooler. Upgrading your engine oil cooler is one of the MOST IMPORTANT upgrades you can do if reliability and longevity is your goal.
This Bullet Proof Oil Cooler System is made specifically to fit the International 4200, VT365 Trucks. Because reliability is a necessity for these vehicles, this version includes the Heavy Duty oil cooler and the Cold Weather Kit. These upgrades ensure that the trucks oil comes up to temperature as quick as possible and then stays where it needs to be for optimal engine performance.
How the Bullet Proof Oil Cooler Kit Works:
The Neal Technologies Oil Transfer Block (protected by US Patent) replaces the OE engine oil cooler. The oil transfer block mounts where the OE oil cooler mounted and it utilizes OE gaskets and hardware to retain the assembly to the engine.
Engine oil is directed through extreme duty hose to the externally mounted oil filter and then to the air-to-oil cooler. In order to maintain or exceed OE engine oil heat removal, an effective liquid to air heat exchanger needed to be utilized. Further, this new engine oil cooler needed to have sufficient air flow to maximize heat transfer.
The supplied engine oil cooler is mounted just behind the condenser. The oil cooler is located in direct air for maximum heat transfer. The radiator fan also acts to move air through the oil cooler. Even during extended idle with little to no air flow, the radiator fan moves more than enough air through the oil cooler to effect more than sufficient heat transfer. This eliminates the pattern failures of early injector failure and early engine wear due to overheated engine oil. This also cures the pattern failure of coolant and oil mixing because of a compromised oil/coolant barrier. This system also has the added benefit of liberating the engine oil temperature from the coolant temperature. This means that during cooler seasons, engine oil temperatures can run cooler than can be accomplished with the OE engine oil cooler. Another benefit of this system is the separation of the oil coolers reliance on the engine coolant for heat transfer. Since the OE oil cooler is the highest point in the cooling system, a low coolant condition could effectively render the OE oil cooler inoperative.
The oil then travels from the supplied oil cooler back to the Oil Transfer Block. The now cooled oil is then directed to the various engine oil circuits. The oil transfer block has an integrated High Pressure Oil Pump (HPOP) filter screen. This screen is constructed from stainless steel and will last the life of the engine. This cures the pattern failure of the High Pressure Oil Pump (HPOP) filter screen failing, resulting in the HPOP failing.
The Engine Coolant (coolant) enters the Oil Transfer Block from the same path as with the OE oil cooler, but the coolant is diverted directly to the EGR cooler. This eliminates the pattern failure of restricted coolant flow to the EGR cooler caused by a plugged or restricted coolant side of the engine oil cooler and coolant reservoir (degas) venting coolant due to the flash boiling of the coolant in the EGR cooler. This also has the added benefit of much cooler coolant entering the EGR cooler. This in turn allows for more heat to be removed from the exhaust gas before it is blended with the air charge. The result is cleaner combustion with fewer emissions. Everybody wins.
