I thought the LTR engine for a 2001 X9 and 209 only had one thermostat, but the local dealership is telling me there's two. Is this correct? If so, where's the 2nd thermostat located? The first thermostat is on top in the themostat housing.

If I'm not mistaken there are two..l one in the triangle shaped housing which is for the raw water pump and one on top of the intake manifold.. Typical on all small block Chevy engines and circulates water through the block
