2006 Pontiac Solstice 2.4L Engine VIN: 1G2MB33B26
Well this fix was too easy. The timing cover removal is a very easy procedure, nothing tricky. The tensioner is right there easy to remove, and a 90 degree turn of the pluger will reset it. I used a left over pin from a timing belt tensioner to hold it down. R...
