soft plastic threading could be an issue!!

cap looks good on the overflow bottle, had a good fit when first installed. However, after engine reached operating temp when you unscrewed cap to check coolant level the underside of cap was turned inward, sort of warped the threading. very hard to screw back on (soft threads) due to engine bay heat? Really shouldn't warp...cheap plastic
