Review on Zerostart 3500043 International Caterpillar Approved by Deejay Allard

Lasted 3 days and didn't heat up the block This is my second zero, 1 from local parts and 1 from Revain. I will not waste time and money on this, I repeat. Get a different, OEM, Ford or 1500w block heater sold here at Revain. That's exactly what I did, and with average temperatures around 20-25 during the day and 0-15 at night, my truck block is operating at Stage 3 and American made.
