Buy Only on Price Point
Fit into block as advertised on my 2007 5.3 litre engine, the installation location point is left bottom rear of block. For my 4x4 I disconnected the front of the front propeller shaft to differential to gain access. Did not drain coolant system but loosened off originally installed threaded plug then quickly swapped heater into threaded bore. Lost no more than 1 litre of coolant.
Buy only on price point as this is basically a commodity item.
The 120 Volt plug has a -18 degree thermostat integrally installed just like the originall OEM plug so if you replace that plug you may get some erroneous codes and messages. Look it up on internet for further info.
