Description

The Lingenfelter 160 degree thermostat offers a premium upgrade for General Motors vehicles, designed to reduce coolant temperatures. This component is a direct drop-in replacement, meaning no modifications are necessary for installation, and it comes complete with the required rubber seal. By lowering engine operating temperatures, this thermostat can contribute to increased horsepower, enhanced performance, and improved driveability. This thermostat is specifically designed for a wide range of GM LS engines, including applications in the Cadillac CTS-V (LS6 5.7L & LS2 6.0L), Chevrolet Corvette (C5 LS1/LS6, C6 LS2, LS3, and Z06 LS7), Chevrolet Impala SS and Monte Carlo SS (5.3L), Pontiac GTO (LS1 5.7L & LS2 6.0L), Pontiac G8 GT (L76 6.0L), Pontiac Grand Prix GXP (5.3L), Cadillac Escalade (6.0L), Chevrolet/GMC Trailblazer/Envoy (5.3L & SS 6.0L), Chevrolet SSR (6.0L), Chevrolet Tahoe/Suburban and GMC Yukon/Yukon XL (4.8L, 5.3L, 6.0L), Chevrolet/GMC Silverado/Sierra (4.8L, 5.3L, 6.0L), and Hummer H2 (6.0L). It replaces GM part number 12600171 and AC Delco part number 131-156.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
