I wouldn't. Adding a stop leak product will successfully clog up your heater core so your heater won't work and can also cause engine overheating due to clogging up the cooling system passages inside the engine. HTH. - Jim


drain cock is on pass. side of radiator. facing the fender. I wouldnt add stop leak either.
