Performance Water Pump & Timing Belt Kit for Toyota 4Runner (1996-2002) 3.4L

Complete Timing Belt & Water Pump Service Kit for 1996-2002 Toyota 4Runner (N180)

What it Does: The Performance Water Pump & Timing Belt Kit synchronizes camshaft and crankshaft rotation while restoring cooling system flow on the 1996-2002 Toyota 4Runner to prevent catastrophic valve train failure and overheating.

The Stock Toyota 4Runner Service Life Limitations

Factory-installed rubber timing belts on the 5VZ-FE degrade progressively due to engine bay heat soak, ozone exposure, and oil vapor contamination. Over extended intervals beyond 90,000 miles, tensioner dampening degrades, idler bearing seals dry out, and internal water pump mechanical seals begin to weep. A worn belt risks tooth shearing or timing drift, while a failing bearing can seize, immediately throwing valve timing out of alignment and leaving the vehicle stranded.

The Engineering Solution

This comprehensive overhaul kit features a high-tensile, heat-resistant EPDM timing belt reinforced with aramid cord construction to eliminate stretch under load. Paired with high-grade steel idler and tensioner pulleys and a heavy-duty hydraulic tensioner, it maintains precise cam-to-crank indexing. The replacement water pump features precision-machined cast alloy housing and sealed, low-drag bearings to resist cavitation and thermal fatigue. Complete front crankshaft and camshaft viton seals ensure positive oil retention at high operating temperatures.
