Review on ❄️ Zerostart 310-0005 Engine Block Heater: Superior Cold Weather Performance by Adam Bates

Revainrating 5 out of 5

Works great 2003 Suburban 5.3

Helps beat the morning chill MN! Installation isn't too bad, just be prepared for a little coolant mess. The connector is very tight and easier to access if you remove the front driveshaft.

Pros
  • New
Cons
  • Bad Experience
