Comments about Alumaseal Radiator Seal Liquid:
The radiator in my 1989 F-150 appeared to have been beaten with a ball pein hammer for the last 23 years. It had a small leak from somewhere (driverside on radiator), and would slowly leak ~3/8 of the coolant out over a day. After doing research on all of the radiator sealers, alumiseal appears to be the least harsh on the cooling system. I put about 80% of the bottle directly into the radiator and within 10 miles there was no leak. If you have a beater that you dont want to spend $$$ on/ dont have time to put in a new radiator, THIS IS PERFECT.
