Where is the leak detection pump located on a 2001 Chrysler minivan?

There isn't a single "leak detection pump" in the traditional sense in a 2001 Chrysler minivan. Leak detection is accomplished through various methods depending on the type of leak (fuel, coolant, power steering, etc.). There's no central pump dedicated solely to leak detection.

If you're experiencing a leak, you'll need to specify *what* is leaking (e.g., coolant, power steering fluid, transmission fluid, fuel) to get a helpful answer about the location of relevant components. For example, the coolant system has a coolant pump, but it's not used for leak detection; its failure *could* indicate a leak, but it's not a leak detection device itself.
