Frequently Asked Questions About Freightliner Coronado Air Tanks, Wraps & Mounting
What size air tanks fit the Freightliner Coronado, and how do I determine which ones I need?
The Freightliner Coronado typically accommodates 25-inch diameter air tanks, though some models can fit up to 26-inch tanks depending on your frame rail spacing. To determine the correct size, measure the distance between your frame rails and the available mounting space behind the cab. Most Coronado models from 2001-2020 use standard 25" x 36" or 25" x 40" tanks. Check your existing tank dimensions or consult your truck's spec sheet to ensure proper fitment.
Are the air tank wraps universal, or do I need specific ones for my Coronado model year?
While many air tank wraps are marketed as universal, Coronado-specific wraps provide the best fit and appearance. The mounting bracket positions vary slightly between pre-2010 and post-2010 Coronado models. Look for wraps specifically designed for your tank diameter (typically 25" or 26") and verify they accommodate your tank's port locations. Stainless steel wraps generally offer more flexibility in fitment than chrome-plated options.
What mounting hardware is included, and what additional parts might I need for installation?
Most air tank mounting kits include steel brackets, grade 8 bolts, and mounting straps. However, you may need to purchase separately: rubber isolators (recommended to reduce vibration), stainless steel bands if upgrading from standard straps, and frame rail adapters if your Coronado has non-standard spacing. Some installations also require air line fittings and thread sealant, which are typically not included with basic mounting kits.
How difficult is the installation process, and what tools are required?
Installation typically takes 3-4 hours for experienced mechanics and requires basic hand tools including socket sets (typically 3/4" and 7/8"), wrenches, and a torque wrench. The most challenging aspect is safely supporting and aligning the heavy tanks during mounting. Many customers report needing a second person or tank jack for proper positioning. Air line connections require proper sealing and pressure testing, so having an air pressure gauge and leak detection solution is essential.
What's the difference between aluminum and steel air tanks for my Coronado?
Aluminum tanks are 40-50% lighter than steel equivalents, reducing overall vehicle weight and improving fuel economy. They resist corrosion better in harsh weather conditions but cost approximately 30-40% more than steel tanks. Steel tanks are more budget-friendly and extremely durable but require regular inspection for rust, especially in salt-belt states. Both materials meet DOT requirements, but aluminum tanks typically carry longer warranties (5-7 years vs. 1-2 years for steel).
