    What should be checked regarding piston-to-bore clearance for the 2003 Chevrolet Astro? Posted by Customer
    A:
    Piston-to-bore clearance should be checked by measuring the bore and piston diameter to ensure they are correctly matched. If the clearance exceeds specified limits, the block should be rebored, and new pistons and rings installed.
