E-cowlboy Radiator Coolant Drain Hose for Volvo & Mack Trucks 1000mm Silica-Gel Molded Coupler

E-cowlboy's Radiator Coolant Drain Hose 9996049 is a durable 1000mm silica-gel hose engineered to drain coolant from 2004–2019 Volvo and 2008–2019 Mack truck radiators quickly and cleanly.

This silicone-style silica-gel drain hose replaces OEM V9996049 and is built to connect to the radiator outlet so you can direct old coolant into a container without spills or tools. It was designed for broad compatibility with Volvo truck models (D11, D13, D16 engines) from 2004 through 2019 and Mack models (MP7, MP8, MP10 engines) from 2008 through 2019. The flexible material resists heat, oxidation and weather exposure to extend useful life under heavy-duty conditions.

How does this hose attach to the radiator outlet?

The hose includes a molded coupler sized to fit the bottom outlet of compatible Volvo and Mack radiators. It slips onto the drain fitting and creates a secure path for coolant to flow directly into your waste container so you avoid spills and messy drip pans.

• Molded coupler that matches OEM drain geometry for a snug fit
• 1000mm length provides reach to place a 5-gallon bucket or recycling jug
• Slip-on connection requires no clamps or special tools

Will this hose withstand engine bay heat and chemicals?

The hose is manufactured from high-grade silica gel designed to tolerate high temperatures and resist corrosion from coolant additives. That material choice reduces cracking, swelling and hardening that shorten the life of ordinary drain tubes.

• Silica-gel composition for high-temperature performance
• Anti-oxidation and anti-corrosion properties for longer service life
• Flexible across a wide temperature range to stay pliable in cold or heat

Which truck models and engines are covered by this replacement hose?

This drain hose is intended for a wide range of heavy-duty Volvo and Mack vehicles. It was made specifically to match the drain fitting used across the listed model years and engine families so it works as a straightforward replacement.

• Volvo Trucks: all models from 2004–2019 with D11, D13, D16 engines
• Mack Trucks: all models from 2008–2019 with MP7, MP8, MP10 engines
• Direct-fit replacement for OEM V9996049 in compatible radiators

How does installing this hose save time during maintenance?

Because it slips onto the radiator outlet and requires no tools, you can drain coolant faster and with less cleanup. The hose length and secure coupler let you position a waste container safely away from the work area, reducing the risk of spills and contaminated surfaces.

• Tool-free connection gets you draining in seconds
• Long reach allows neat coolant disposal into a bucket or recycler
• Reduces cleanup time compared with improvised solutions

Who is this for: This replacement radiator drain hose is aimed at fleet technicians, independent heavy-truck mechanics, and owner-operators who service Volvo or Mack trucks from the specified model years and engine types. It suits anyone who needs a dependable, long-lasting drain solution that simplifies coolant changes and minimizes spills during routine maintenance.
