Kenworth T700 Engine Parts & Cooling

Frequently Asked Questions About Kenworth T700 Engine Parts & Cooling

What model years are these engine cooling parts compatible with for the Kenworth T700?

Most of our Kenworth T700 engine cooling parts are designed to fit model years 2008-2019. However, compatibility can vary based on your specific engine type (Cummins ISX, PACCAR MX, or Caterpillar). Always check the product description for your exact year and engine configuration, or contact our support team with your OEM for verification.

How difficult is it to replace the radiator or cooling fan on a T700, and what tools do I need?

Radiator replacement typically takes 3-5 hours for experienced mechanics and requires basic hand tools, a coolant drain pan, and potentially a hoist for heavier units. Fan clutch replacements are generally easier at 1-2 hours. Common tools needed include socket sets (metric and standard), coolant pressure tester, and torque wrench. We recommend having shop manual specifications for proper torque values and coolant capacity.

What's the difference between OEM and aftermarket cooling parts, and how does it affect warranty?

OEM parts are manufactured to exact factory specifications and typically carry a 1-2 year warranty. Our aftermarket options from brands like Dorman and TYC meet or exceed OEM standards at 30-40% less cost, usually with similar warranty coverage. Aftermarket parts won't void your truck's warranty if installed correctly. Many fleet operators choose quality aftermarket parts for cost savings without sacrificing reliability.

How often should I replace coolant hoses and thermostats on my T700?

Coolant hoses should be inspected every 6 months and typically need replacement every 4-5 years or 400,000-500,000 miles, whichever comes first. Look for soft spots, cracks, or bulging. Thermostats generally last 500,000-750,000 miles but should be replaced if you're experiencing temperature fluctuations or overheating. Consider replacing the thermostat whenever you service the cooling system to prevent roadside failures.

What are the signs my T700's water pump is failing, and can I replace just the pump without other components?

Common water pump failure signs include coolant leaks near the pump, grinding or whining noises, engine overheating, and visible play in the pump pulley. While you can replace just the water pump, we recommend also replacing the belt, tensioner, and coolant at the same time since you're already accessing the area. This prevents repeat labor costs and ensures optimal cooling system performance.
