FAQs
Q1: How do I verify if this H2D turbocharger fits my Volvo truck?
Please check the nameplate on your current turbocharger for the part number 3526008 or the Volvo number 864592. Since the 12L engine had several regional variations, matching this specific 6-digit or 7-digit OEM number is the most reliable way to ensure a correct fit.
Q2: My truck is over 30 years old. What should I check before installing this new turbo?
For classic Volvo trucks, it is critical to replace the Oil Feed Line during installation. Over decades, carbon sludge (coking) can build up inside the old line, restricting oil flow to the new precision bearings and causing instant failure. Also, ensure your engine's oil pressure is within factory specs.
Q3: What is "K18 Nickel-Alloy" and why does it matter?
K18 is a specialized high-nickel alloy used for turbine wheels. It is designed to maintain its shape and structural strength at exhaust temperatures exceeding 900°C. This is vital for 12L heavy-duty engines that maintain high boost levels over thousands of miles.
Q4: What type of warranty do you provide for international logistics and fleets?
We understand that Volvo F12 trucks are still workhorses in many parts of the world, which is why we stand behind our quality with full technical support for fleet owners and professional workshops worldwide.
Q5: Do you provide worldwide shipping? What is the delivery timeframe?
We ship globally via premium carriers like DHL, FedEx, and UPS, as well as sea freight for bulk orders. In-stock items are typically dispatched within 24–48 hours. Express delivery to North America and Europe usually takes 5–7 business days.
