I have a stock 2003 WRX with about 65K miles. Last week, while pulling out of a parking lot, I heard a sharp crack and my car died. Looked under the hood and saw the A/C belt shredded. Figured that was the extent of the problem. Unfortunately, that was not all she wrote. Closer inspection revealed that the A/C idler failed and probably caused the belt to shred. In addition, the timing belt tensioner failed which, threw the belt and bent some valves.
Now, I get to pay for a substantial amount of work. So, my question is do I need to replace the water pump? Are there any other additional parts that need to be replaced when the timing belt fails? What is the long term prognosis for recovery?
One final question, once the car is up and running, I plan to replace the spark plugs. Can someone recommend some spark plugs? I've been told Bosch and Champion. I've seen good reviews on NGK. Platinum vs. Iridium?
Thanks in advance for the help.
