Peterbilt 389 Glider Radiators

Frequently Asked Questions About Peterbilt 389 Glider Radiators

Will this radiator fit my Peterbilt 389 glider kit exactly, or will I need to modify mounting brackets?

Most radiators listed in this category are designed to match the core dimensions and mounting points used on Peterbilt 389 glider kit applications. However, glider builds can vary depending on the engine, cooling package, and chassis configuration used during assembly, so it's important to verify core size, inlet/outlet locations, and mounting hole spacing against your specific truck before ordering. If you're unsure, our sales team can help confirm fitment based on your build specs.

What material is the radiator core and tanks made from, and how does that affect durability?

Radiators in this category are typically constructed with aluminum cores for efficient heat transfer paired with either aluminum or plastic tanks, depending on the manufacturer and model. Aluminum construction is generally favored for its resistance to corrosion and its ability to handle the heat loads of heavy-duty diesel applications over the long haul.

Can this radiator handle the cooling demands of the engine used in my glider build?

Cooling capacity depends on the radiator's core thickness, fin density, and overall design, which vary by product. Since glider kits often pair a Peterbilt 389 with different engine options than the factory originally intended, it's important to match the radiator's rated cooling capacity to your specific engine's horsepower and heat output rather than assuming all radiators in this category are interchangeable in performance.

What's involved in installing a replacement radiator, and should I expect to reuse my existing hoses and shrouds?
