EV 9409191C A/C Evaporator Core-DIESEL, Eng Code: MX-13

It’s an A/C evaporator core used inside the truck air conditioning evaporator housing to absorb heat and help cool the cab air. This EV-9409191C evaporator core is built for diesel applications and is intended for systems matching the MX-13 diesel engine compatibility noted for this part. Replacing a restricted or leaking core can restore cooling performance and reduce strain on the A/C system.

This part is specified for diesel engines with the MX-13 engine code, making it a match for applications calling for that fitment. Always confirm the EV-9409191C evaporator core against your truck’s VIN, OEM number, or the existing core dimensions before ordering. Compatibility can vary by truck model year and HVAC configuration even with the same engine family.

Weak cooling, intermittent cooling, or an oily residue at the evaporator case drain can indicate a failing diesel A/C evaporator core. A musty odor and persistent fogging can also point to a contaminated or restricted A/C evaporator core. A proper diagnosis typically includes leak testing with dye or an electronic detector and verifying system pressures.
