Product Details

Gates EMH045 is part of the Gates Emission Control Hose line, a product line focused on replacement hoses for crankcase ventilation and emission routing. This hose is built to OE-exact dimensions, with a 15 mm inside diameter and 240 mm centerline length, so it matches the specified routing between the valve cover and intake tube. For buyers searching for a Toyota 4Runner valve cover to intake tube breather hose or a Toyota FJ Cruiser crankcase ventilation hose, EMH045 provides the correct fitment profile.

What It Helps Address

• Cracked or hardened crankcase breather hose material
• Vacuum leaks at the valve cover to intake tube hose connection
• Improper crankcase ventilation routing
• Emission system performance issues caused by hose deterioration
• Oil vapor transfer problems related to a damaged breather hose

Installation Notes

Confirm the hose routing, end style, and dimensions before installation. The push-in design should seat fully at the valve cover and intake tube connection, and the protective sleeve should be positioned as originally routed. Inspect nearby fittings and the intake tube for wear, contamination, or damage before installing the new hose.

Quality Assurance

Gates builds this replacement hose as an OE-exact emission control component using high-quality materials for durability and service life. EMH045 is intended to restore the original hose function and maintain the specified crankcase ventilation path on compatible Toyota vehicles.
