Can leaking coolant hose cause spark plugs to get corroded?
fist of all.. no. if your coolant hose is leaking then you will probably run out of coolant and blow a head gasket and you dont want that.second of all i have a question for you:is your coolant hose leaking or are you just losing coolant all the time? if your hose isnt leaking, then is possible you have a blown head gasket or a cracked block or a blown head gasket, and either of those two will cause ur spark plug too look nasty when u take it out, but there are also many different reasons why your spark plug could corrode.
