Frequently Asked Questions About Kenworth T700 Radiator Tubes, Gaskets & Hoses

What years and engine models are these radiator components compatible with?

Our Kenworth T700 radiator tubes, gaskets, and hoses are designed to fit models from 2008 through 2019. However, compatibility varies based on your specific engine type - whether you have a Cummins ISX, PACCAR MX-13, or Caterpillar C15. Always check the product description for your exact engine model and serial number range, or contact our support team with your VIN for verification before ordering.

How difficult is it to replace radiator hoses and gaskets, and what tools do I need?

Most radiator hose replacements can be completed in 1-2 hours with basic hand tools including pliers, screwdrivers, and a drain pan. Gasket replacements typically require removing the radiator, which adds 2-3 hours to the job. You'll need a socket set, torque wrench, and potentially a coolant pressure tester. Many drivers handle hose replacements themselves, but gasket work often requires mechanical experience due to the need for proper torque specifications and alignment.

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

OEM components are manufactured to exact factory specifications and typically carry a higher price point but ensure perfect fit and longevity. Our aftermarket options from trusted brands like Gates and Dayco meet or exceed OEM standards at a more competitive price. For critical applications or warranty concerns, we recommend OEM. For routine maintenance on older trucks, quality aftermarket parts provide excellent value without compromising performance.

How often should I inspect and replace radiator hoses and gaskets?

Radiator hoses should be inspected every 6 months or 50,000 miles for signs of cracking, swelling, or soft spots. Most hoses last 4-5 years or 400,000-500,000 miles under normal conditions. Gaskets typically last the life of the radiator (7-10 years) unless disturbed during service. Replace hoses immediately if you notice coolant seepage, bulging, or deterioration at the clamps. Preventive replacement during major service intervals can prevent costly roadside breakdowns.

What are the most common signs of failing radiator tubes or hoses?

Watch for coolant puddles under your truck, especially after parking overnight. Other warning signs include a sweet smell in the cab, white residue around hose connections, engine temperature fluctuations, and low coolant levels requiring frequent top-offs. Soft or spongy hoses when squeezed (with engine cold) indicate internal deterioration. Any visible cracks, especially near clamps or bends, require immediate replacement to prevent catastrophic failure.
