[quote=Anonymous][quote=Anonymous]The only difference between current police cars (called commercial/LE chassis pkg in the industry) and regular cars are: dual batteries, higher output alternator (both for powering more electronics found in LE vehicles) [b]and a larger radiator and transmission cooler (for pursuits/chases[/b]

NP-Doesn't that have to do with cooling? Idling produces a lot of heat so a transmission cooler or larger radiator would absolutely help with over heating while idling. PP was being an ass.[/quote]

Idling consumes the absolute minimum amount of fuel required to keep the engine running when not being turned by rotational inertia forces from the driveline (ie coasting with your foot off the gas pedal). In terms of thermodynamic energy conversion, it is the absolute lowest level of fuel consumption and ergo the absolute lowest level of heat generation possible in a running engine. So idling will NOT overheat a car, period*.

* unless the car has a broken fan clutch or fan motor, in which case it’s not pulling air through the radiator at all.
