[yenghawj]

would this work with modern vehicles?

[metalrescue]

@yeng Yes-Metal Rescue will work on ALL vehicles this way. Follow Ken's instructions. Drain the cooling system and then follow up by flushing the system. When steps are complete you can add Metal Rescue to your cooling system filling to the top DO NOT add water. Note that Ken runs his engines with Metal Rescue in the cooling system to elevate the temp. throughout the process (speeds process). The process Should take from 6-12 hours depending on the severity of the rust in system & temp.
