Gasket
The FP Diesel 5123570 gasket restores a tight seal between the thermostat housing and engine on Detroit Diesel Series 92 platforms. A compromised housing gasket can lead to slow coolant loss, overheating, and uneven warm-up. This replacement matches OEM shape and sealing surface coverage for consistent compression under heat cycling and vibration. Ideal for thermostat swaps or cooling system repairs, it helps keep your Detroit running at the correct operating temperature with leak-free reliability.
