Complete 1823182C95 Oil Cooler Gasket Kit for Navistar DT466E Engine – Oil Cooler Seal Set

Engine oil cooling is essential for maintaining proper lubrication and preventing overheating in high-output diesel engines. For the Navistar DT466E engine, the 1823182C95 oil cooler gasket kit provides all necessary seals, gaskets, and O-rings to rebuild the oil cooler assembly. Leaking oil cooler gaskets can cause coolant-oil cross-contamination, loss of oil pressure, and eventual engine failure. This complete gasket kit restores a leak-free seal and ensures your DT466E operates reliably for years to come.

Engineered for Navistar DT466E Engines

The DT466E is an electronically controlled, 7.6L inline 6-cylinder diesel engine widely used in International trucks, school buses, and agricultural equipment. The oil cooler on this engine is a plate-and-fin or stacked-disc type that transfers heat from engine oil to engine coolant. The 1823182C95 gasket kit includes the oil cooler base gasket, cooler element O-rings, end cover gaskets, and sometimes coolant bypass valve seals. This kit is designed to withstand high temperatures and pressure cycles without shrinking or hardening.

What’s Included in the 1823182C95 Gasket Kit?

A typical complete oil cooler gasket kit includes:

• Oil cooler base gasket (between block and cooler housing)

• Oil cooler element O-rings (inner and outer)

• Oil cooler end cover gasket

• Coolant bypass valve seal (if applicable)

• Oil filter adapter gasket

• Various small O-rings for coolant and oil passages

Why Choose This Oil Cooler Gasket Kit?

1. OEM Equivalent Materials: High-quality rubber (NBR or HNBR) and fiber gaskets resist oil, coolant, and temperature extremes.

2. Complete Solution: Everything needed for a single repair – no need to source separate seals.

3. Leak-Free Seal: Prevents oil from entering the cooling system (which causes sludge) and coolant from entering the oil (which ruins bearings).

4. Cost-Effective: Replacing just gaskets is far cheaper than replacing the entire oil cooler assembly.

Symptoms of Failing Oil Cooler Gaskets

• Milky oil (coolant in oil) – often visible on dipstick or oil fill cap

• Oil film in coolant reservoir (brownish residue)

• Loss of coolant without external leaks

• Low oil pressure due to oil dilution

• Engine overheating (coolant flow restricted by oil contamination)

• White smoke from exhaust (coolant burning)

Installation Recommendations

• Drain both engine oil and coolant before starting.

• Remove the oil cooler assembly from the engine block.

• Thoroughly clean all mating surfaces – use a gasket scraper and brake cleaner.

• Inspect the oil cooler element for cracks or blockages; replace if damaged.

• Lubricate new O-rings with clean engine oil before assembly.

• Torque fasteners to Navistar specifications (typically 25-35 Nm for cooler mounting bolts).

• After installation, refill with fresh oil and coolant, then run engine and check for leaks.

Conclusion

The 1823182C95 oil cooler gasket kit for Navistar DT466E engine is an essential repair solution for preventing oil-coolant cross-contamination. Whether you are servicing an International 4700 truck, an IC Bus CE school bus, or a Case IH Magnum tractor, this complete seal set ensures a durable, leak-free oil cooler assembly.
