I have an '07 Uplander with the 3.9 V-6. I need to replace the thermostat, and can't seem to figure out where it is on this motor. I don't have an owners manual for it. Got it used a few weeks ago, and I want to get the cooling system flushed out before the cold weather sets in.

Thanks, Mike

The t/stat housing is on the front of the engine, just left of the oil filter. Follow the radiator hose to it.

I'm going to guess lower radiator hose. Thanks.
