FAQs

Q1: How do I verify if this H1C turbocharger fits my Cummins 4BT engine? 

Please check the nameplate on your current turbocharger for the part number 3522900 or the Cummins OEM number 3802290. The H1C model was common on early mechanical 4BT engines; matching the 7-digit part number is the most reliable way to ensure a correct fit.

Q2: Is this H1C turbocharger water-cooled or oil-cooled? 

This specific H1C model is Oil Cooled. It relies on the engine's oil circulation for both lubrication and cooling of the bearing housing. Ensure your oil lines are clean and the oil pressure is within factory specs during installation.

Q3: Does it include the compressor inlet and exhaust outlet gaskets? 

Our standard turbocharger package typically focuses on the unit itself. We recommend purchasing a new high-temperature gasket kit separately to ensure a perfect, leak-free seal during the installation process.

Q4: What type of warranty do you provide for mechanical 4BT engines? 

We understand that Cummins 4BT engines are often used in demanding agricultural and industrial environments, which is why we stand behind our quality with full technical support for our global customers.

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.
