Frequently Asked Questions About Peterbilt 367 Engine Parts & Cooling

What model years of Peterbilt 367 trucks are compatible with your engine cooling parts?

Our engine cooling parts are designed to fit Peterbilt 367 models from 2007 to present. However, there are important differences between pre-2011 and post-2011 models due to emissions system changes. Pre-2011 trucks typically use different radiator configurations and coolant reservoir designs. Always verify your specific truck's OEM and engine model (ISX, C15, or DD15) when ordering to ensure proper fitment.

Are aftermarket radiators and cooling components as reliable as OEM parts?

Quality aftermarket radiators from reputable manufacturers like Dura-Lite, Freightliner Alliance, and Modine meet or exceed OEM specifications. These units feature aluminum cores with reinforced plastic or aluminum tanks, identical fin density to factory specs, and proper mounting brackets. Many drivers report 500,000+ miles on quality aftermarket radiators with proper maintenance. Look for parts that carry at least a 2-year warranty for peace of mind.

What are the most common installation challenges when replacing cooling system components?

The most frequent installation issues include: coolant hose routing confusion (especially on trucks with APU systems), difficulty accessing lower radiator mounting bolts, and proper torque specifications for aluminum components. Plan for 3-4 hours for a radiator replacement. You'll need basic hand tools plus a torque wrench capable of 15-85 ft-lbs. Many customers find removing the charge air cooler first provides better access. Always replace thermostats and pressure caps when doing major cooling work.

How do I choose between aluminum and plastic radiator tanks for my 367?

Aluminum tanks offer superior durability and heat dissipation, making them ideal for heavy-haul applications or hot climate operation. They typically last 7-10 years. Plastic tanks are more affordable and work well for standard highway applications, lasting 4-6 years on average. Consider aluminum if you frequently gross over 70,000 lbs, operate in mountainous terrain, or have had repeated plastic tank failures. Both options use aluminum cores, so cooling efficiency is comparable.

What coolant type and capacity does the Peterbilt 367 require?

Peterbilt 367 trucks require heavy-duty extended life coolant (ELC) meeting CAT EC-1 or Cummins 14603 specifications. Total system capacity varies by engine: ISX engines hold 11-12 gallons, CAT C15 engines require 13-15 gallons, and Detroit DD15 engines use 12-14 gallons. Never mix conventional green coolant with red ELC coolant. When switching coolant types, perform a complete system flush. Most cooling system failures stem from improper coolant maintenance rather than component defects.
