Hino 238-338 Truck Radiators

Frequently Asked Questions About Hino 238-338 Truck Radiators

Will this radiator fit my Hino 238 or 338 truck without modification?

Radiators in this category are built to match the OEM specifications for Hino 238 and 338 model trucks, including core dimensions, tank design, and mounting points. However, because production years can bring small design changes, it's always a good idea to confirm your truck's model year and engine configuration against the product details before ordering to ensure a direct fit.

What material is the radiator core made of, and how does that affect cooling performance?

Most replacement radiators for the Hino 238-338 are constructed with either an aluminum core and plastic tanks or an all-aluminum design, depending on the manufacturer. Aluminum cores are valued for their heat dissipation properties and resistance to corrosion, which helps maintain consistent engine cooling under heavy-duty operating conditions.

Is professional installation required, or can I install the radiator myself?

While experienced DIY mechanics can install a radiator with proper tools and safety precautions, we recommend having the installation performed or checked by a qualified diesel technician. Proper installation includes correctly seating hose connections, torquing mounting hardware, and bleeding the cooling system to prevent air pockets that can cause overheating.

How do I know if my old radiator needs to be replaced rather than repaired?

Common signs that point to replacement rather than repair include persistent leaks at seams or tanks, visible core damage such as bent fins or corrosion, frequent overheating despite proper coolant levels, and cracked or brittle end tanks. If your radiator has been repaired multiple times or shows widespread core damage, replacement is typically the more reliable long-term solution.

Does the radiator come with a warranty, and what does it typically cover?

Warranty coverage varies by manufacturer and specific product, so we recommend checking the warranty details listed on each individual product page before purchasing. In general, radiator warranties cover manufacturing defects in materials and workmanship, but they typically do not cover damage caused by improper installation, road debris, or lack of routine coolant system maintenance.
