So I have a 07 TB with the 4.2L I6 (aka- gas hog!!!) I have been brain storming forever on how to save gas in it- just like everyone else. My dad and I came up with an idea, but dont know how it will work and was wondering if anyone could give me some input. The fan on the engine is ran by the engine (which uses gas), we were thinking of putting maybe two 12" electric fans in place of the existing fan. The fan that is there now uses alot of power and gas to run and cool the engine. Does anyone know about the sensors that may be in the coolant system or the fan system. I dont want to do all these modifications and then have some sort of strange sensor problem, seeing how the new engines have all sorts of electrical sensors and stuff. I just want to see if anyone thinks it is worth it is about a $200 fix!!!!!
