FAQs for Wholesale 89019400 H6 AC Compressor
Does this H6 compressor fit both the 1500 and the heavy-duty 2500/3500 Silverado models?
Yes. This 89019400 unit is a standardized H6 model used across the GMT800 light truck and heavy-duty chassis from 1999 to 2002. The mounting configuration and 110mm PV6 pulley are consistent, allowing you to service a massive range of GM trucks with a single SKU?
Is this compressor compatible with the high-output V8 engines like the 6.0L Vortec?
Absolutely. Our H6 units are built with reinforced internal components designed to handle the thermal loads and high-speed operation of the Vortec V8 engine family. It provides consistent high-pressure output, ensuring the large cabins of Silverado and Express vehicles stay cool?
How do you ensure the electromagnetic clutch survives the stop-and-go duty of delivery vans?
Commercial vans like the Savana and Express face extreme duty cycles. We use premium-grade copper for our clutch coils and high-carbon steel for the pulley to prevent thermal failure and slippage during frequent cycling, which is a major pain point for fleet operators?
What is the standard lead time for wholesale container-load orders?
For our high-volume B2B partners, we maintain a focused production schedule for classic GM parts. Our standard lead time for bulk wholesale orders is 60 days. This includes 100% factory performance testing and secure export-grade palletization?
Can we customize the branding and technical stickers for our regional wholesale line?
We offer professional private label services. We can laser-etch your brand logo and custom part numbers directly onto the H6 housing. Additionally, we can provide customized, high-strength packaging that features your corporate branding for a complete private-label solution?
What quality control steps are taken to ensure these units are leak-free upon arrival?
Every 89019400 compressor undergoes a multi-stage leak test using high-pressure nitrogen. We also perform a comprehensive functional run-in test to check for noise and vibration, ensuring that when your clients install these units, they perform to OE standards immediately?
