Frequently Asked Questions About Hino 238-338 Truck Radiator Tubes, Gaskets & Hoses

Will these radiator components fit my specific Hino 238 or 338 model year?

Our radiator tubes, gaskets, and hoses are designed to fit Hino 238 and 338 models from 2005-2010. However, there can be variations based on engine type (J05D-TA or J08E-TA) and whether you have a manual or automatic transmission. We recommend checking your VIN or calling our support team at 1-888-875-7787 with your truck's specifications to ensure proper fitment before ordering.

What's the difference between OEM and aftermarket radiator hoses, and which should I choose?

OEM hoses are manufactured to original Hino specifications using EPDM rubber rated for temperatures up to 257?F. Aftermarket options we carry meet or exceed OEM specs but cost 30-40% less. Both options typically last 4-6 years under normal conditions. If you're doing preventive maintenance, aftermarket is usually sufficient. For warranty work or if you need maximum longevity, OEM is recommended.

Can I install these radiator components myself, or do I need special tools?

Most radiator hose replacements can be done with basic hand tools including pliers, screwdrivers, and a drain pan. Upper and lower radiator hoses typically take 30-45 minutes each. However, some heater hoses require removing the dash panel, which can take 2-3 hours. Gasket replacements require draining the cooling system completely and may need a torque wrench for proper installation. Always replace hose clamps when installing new hoses.

How do I know when my radiator hoses or gaskets need replacement?

Check for these warning signs: soft or spongy hoses when squeezed, visible cracks or bulging, coolant residue around connections, or coolant smell in the cab. For gaskets, look for coolant leaks at connection points or a drop in coolant levels without visible external leaks. We recommend inspecting hoses every 6 months and replacing them preventively every 4-5 years or 200,000 miles.

Are silicone radiator hoses worth the extra cost over standard rubber hoses?

Silicone hoses cost 2-3 times more than standard EPDM rubber but offer superior heat resistance (up to 350?F), better flexibility in cold weather, and typically last 8-10 years. They're ideal for trucks operating in extreme temperatures or those with modified engines producing higher heat. For standard applications and regular maintenance schedules, quality rubber hoses provide excellent value and performance.
