Brand Tiers for Your Skylark
- Premium Tier (ACDelco, Gates): ACDelco is General Motors' official parts brand, and many of its parts are identical to what was installed at the factory. This makes it a top choice for GM vehicle owners. Gates is also a highly respected brand, well-known for its quality cooling system components and belts. Both are excellent choices for reliability and long-term use.
- Standard Tier (GMB): GMB is often recommended for its blend of quality, price, and wide coverage. They are known for making reliable pumps that are a good fit for daily drivers and often come with the necessary gaskets and hardware.

Pro Tip: When replacing your water pump, it's a good idea to also replace the thermostat and any related belts, like the serpentine belt. These parts are often removed during the replacement process anyway, so doing it all at once can save you time and labor down the road.
