Jiffy Lube isn't a flush. They only perform a coolant swap. You want a power flush to dislodge any gunk in the core. Call some shops in the yellow pages until you find one that does a power flush. That means pressurized water or pressurized air and water.
I used to work at a Jiffy Lube.
What you want to see is both radiator hoses disconnected, the lower hose placed in a drain and a pressurized source hooked up to the upper hose.
Conversely, if you have good water pressure at home, you can disconnect the heater hoses from the engine, and connect one to the garden hose. Just be sure to collect the old coolant for proper disposal.
