HX35 Frame Highlights (reference)

HX35 / HX35W turbochargers are known for high-efficiency compressor design and journal bearing construction commonly used in diesel / off-road applications. Exact wheel / housing specs vary by version, so fitment should be verified by nameplate.

Common Symptoms of Turbo Failure

Before Installation (Highly Recommended)

To avoid repeat turbo failure, check:

1. Air filter & intake leaks

2. Oil feed / return lines (clean or replace if carbon blocked)

3. Intercooler and charge pipes (oil pooling)

4. Exhaust leaks / restrictions

Installation Notes (Turbo Life Matters)

• Pre-lube the turbo with clean engine oil before first start

• Replace engine oil and oil filter

• Ensure oil pressure builds before loading the engine

• Idle 3–5 minutes after installation; cool down before shutdown
