Tiny intake coolant leak, advice needed
Aviation Sealer for bolts and threads.
As preventive maintenance 1/2 cup Dike Radiator sealer. Proven to work well, does not clog things up.
Although Bottle recommends up to 1 pint per 4 gallons coolant, does not take much to seal up the annoying small drip.
Got super small drip/seep? Seals them up.
Threads need to be clean and dry before application where they go into the water jacket, and apply sealer to both parts.
