Dealer replaced opti-spark but did not replace the water pump which was ready to go out. The water pump let go and took out the brand new opti-spark. |
13750 mi US $225 |
Dealer installed new water pump and another opti-spark that the old pump took out (dealer should have replaced the pump when he replaced the opti-spark). Also, when the first opti-spark was replaced with the old failing pump, the technician pinched off the vacuum tube (that vents the opti-spark), so when the water pump stared leaking it immediately took out the new opti-spark. This was fixed by the owner....me! |
