Title: Doesn't work -- poor wiring connection
Review: I installed one of these in a 2000 Yukon. Freeze plug type heater installed easily. But the wiring that plugs into the heater is very difficult to get on, but once on is too loose to stay in place.I ordered a replacement but the second cord had the same issue. I checked to see if it worked by putting the vehicle on a ramp and leaving it plugged in overnight. The block was still cold the next morning, the plug was loose and wouldn't stay attached, and the wire sparked when I wiggled it.I'm going to pull the wire. No sense in removing and and returning the second heater because it'll cost me more in coolant than I'll get in refund.I won't buy one of these again and I won't recommend them to anyone.
Is the review positive or negative?
