RubbeRy stuff

Give those coolant hoses a squeeze to ex­pose any cracks and hard­ness. Check all ac­ces­si­ble gaiters and rub­ber cov­ers for splits, too. There’s a rea­son why con­doms have a use-by date. The same should go for rub­ber items on a car, as they could have sim­i­larly costly con­se­quences. Coolant hoses, espe­cially nat­u­ral rub­ber prod­ucts, of­ten lose their sup­ple­ness over time, mean­ing that their abil­ity to take the flex be­tween a vi­brat­ing en­gine and a rel­a­tively solidly-mounted ra­di­a­tor will be im­paired. The same goes for their abil­i­ties to ex­pand and con­tract with fluc­tu­a­tions in coolant tem­per­a­ture. Brit­tle hoses can rup­ture un­ex­pect­edly, with con­se­quent loss of coolant and po­ten­tial en­gine seizure. Drive­shaft and steer­ing gaiters suf­fer in much the same way, splurg­ing out lubri­cant and leav­ing vi­tal joints dry.
