At 0800 hours while on the streets returning from a CO Alarm, the Temple Fire Company and Goodwill Fire Company alerted to a parking lot in the 2800 block of Centre Ave for a reported car fire. AC11 requested E13 be dispatched as well. R11 w/ AC11 arrived with smoke pushing and employees using ABC dry chemical extinguishers. We went in service with a PW until E13 arrived and stretched a booster line to wet the area down. Units were the released.
