Hino 238-338 Truck AC Driers & Compressors

Frequently Asked Questions About Hino 238-338 Truck AC Driers & Compressors

Will this AC drier or compressor fit my Hino 238 or 338 model year?

Hino 238 and 338 trucks were produced across several model years with different engine and AC system configurations. Before ordering, check the part number against your truck's build sheet or existing component, and compare mounting points, fitting sizes, and connector types to make sure the replacement matches your specific truck.

How do I know if I need a new compressor or just a new AC drier?

An AC drier (receiver drier) filters moisture and debris from the refrigerant and is often replaced anytime the AC system is opened up for repair. A compressor failure usually shows up as unusual noise, seized operation, or a complete loss of cooling. If your system has been low on refrigerant for a while or has metal debris in it, both components may need attention since contamination can damage a new compressor quickly.

Should I replace the AC drier every time I replace the compressor?

Yes, it's standard practice to replace the AC drier whenever the compressor is replaced or the AC system is opened. The drier accumulates moisture and contaminants over time, and reusing an old one can introduce debris or moisture into a new compressor, shortening its life.

What should I check before installing a new compressor?

Flush the AC lines and condenser to remove old refrigerant oil and any metal particles from a failed compressor, confirm the new compressor comes with or matches the correct amount of refrigerant oil, and always install a new drier and o-rings. Evacuate and properly recharge the system with the correct refrigerant type after installation to avoid premature failure.

Do these parts come with a warranty, and are they new or remanufactured?
