Why is my Thermostat an 04-08 ls2/3/truck ????
Was changing to a 160 stat, drained all the coolant and realized the new one I got is different and doesn't fit. the One I received is the oneon the right which is correct for my model. .... Mine is the one on the left in the pics.I guess somewhere down the line the previous owner changed the pump and went with an ls2/3 pump. pros/cons of having an ls2/3 pump? better design? replacement? or cheaper ?

Damnit this same exact thing happened to me last night. I received a Hypertech 180* thermostat and was excited to change my coolant for the first time in 6 years/150K miles (I know, I know). The thermostat I received looks like the one on the right, but it didn't fit when I went to replace mine. The cast "support arms" on the Hypertech unit wouldn't fit in the car. I broke the new thermostat trying to force it in.
My old/current thermostat looks like the one on the left. I replaced the water pump in 2004 with one I got at the GM parts desk. Didn't know it would be different. Blah.
