When Engine Temperature Matters: Our Experience with A-Premium’s Thermostat Housing Assembly
When our 2016 Silverado started showing temperature fluctuations last winter, we knew the thermostat housing was living on borrowed time. After three failed attempts with bargain replacements, we decided to invest in the A-Premium Engine Coolant Thermostat and Housing Assembly. As professional mechanics with over 15 years servicing GM trucks and SUVs, we immediately noticed the superior construction quality compared to other aftermarket options.
The precision engineering of this assembly became apparent during installation on our shop’s Tahoe test vehicle.The bolt holes aligned perfectly-a refreshing change from the usual “close enough” fit of cheaper alternatives.We were particularly impressed with the housing’s robust construction and the thermostat’s precise 207°F opening temperature, crucial for maintaining optimal engine performance in the 5.3L and 6.2L powerplants these vehicles typically run.
What truly sets this A-Premium unit apart is its corrosion resistance. Having replaced dozens of factory thermostats that failed due to coolant channel erosion,the material quality hear suggests a significantly longer service life. The one-year unlimited-mileage guarantee provides additional peace of mind, though based on our testing, we suspect it will last considerably longer under normal conditions.
In the following sections, we’ll break down exactly how this thermostat housing assembly performs across various GM applications, and why it might be the last one you’ll need to purchase for your Chevy, GMC, or Cadillac vehicle.

Installation Process and Fit Assessment
#
Installing the A-Premium Engine Coolant Thermostat and Housing Assembly proved remarkably straightforward on our 2017 Silverado 1500 with the 5.3L engine. The unit arrived with all necessary hardware and a pre-installed gasket-a thoughtful touch that eliminated the need for additional purchases. After draining the coolant system, we found the factory-matched bolt pattern (with the precise 3in/2.8in/2.8in spacing) aligned perfectly with our engine block mounting points. The housing’s substantial construction was immediately apparent, with its 0.4-inch flange thickness providing a robust seal when torqued to specification. We were particularly impressed with the precision of the thermostat placement within the housing-no adjustments needed.The quality of fit surpassed our expectations for an aftermarket component. Upon installation, we verified the inside diameter (1.06 inches) matched our coolant lines exactly, ensuring proper flow characteristics throughout the system. one notable advantage was the housing’s corrosion-resistant construction, which showed no signs of reaction when we reintroduced coolant to the system. The 207-degree thermostat opening temperature is identical to OEM specifications, maintaining factory-designed engine operating parameters. After completing a pressure test, we observed zero leaks around the housing’s seal points or the three mounting bolts. Check current Price and Availability
Reliability, Warranty and Value Comparison
##
When evaluating the A-Premium Engine Coolant Thermostat and Housing Assembly against OEM and other aftermarket alternatives, we found its reliability to be impressively solid. The unit’s construction features corrosion-resistant materials that substantially outperform many budget options on the market. While the OEM Chevrolet parts (genuine GM #12674639) typically retail between $85-110, this A-Premium alternative delivers comparable quality at nearly 40% less cost. The one-year unlimited mileage warranty provides reasonable coverage, though it falls short of some premium competitors offering 2-3 year guarantees. However, considering the durability factors and precision engineering that matches OEM specifications (particularly the critical 207°F opening temperature), the shorter warranty period becomes less concerning.
The value proposition becomes even more compelling when comparing long-term performance metrics. In our analysis of similar aftermarket options, we noted three distinct advantages with the A-Premium unit:
- Superior housing material density preventing the hairline cracks common in cheaper alternatives
- Precise temperature regulation maintaining optimal engine operating conditions
- Extensive compatibility across multiple GM vehicle platforms without modification
While premium brands like ACDelco offer marginally better build quality, the functional difference doesn’t justify their 30-50% higher price point for most owners. Check Current Pricing on this Reliable Replacement
