: Head Gasket - Ran in 2nd Gear & Temp Went Down?

I test drove a 2003 SLS last night and ran it in 2nd gear at 75 mph for roughly 5 miles and the temp gauge actually went down about 2-3 degrees rather staying constant or going up. Keep in mind that it was about 8 degrees above 0 last night here in Illinois. Is my thinking correct that since the engine was running at a higher rpm that the water pump was pumping more coolant through the engine, thereby lowering the engine temperature, and hence the head gaskets are probably ok? Thanks for any comments.
