....if you are looking for a temp fix....a product like water glass...an additive used for years to seal small leaks is available at your local drug store...a silicon type of product....very easy to use.....ceramic engine seal will work....by Moroso.....those pills used by GM in the Nineties to seal aluminum radiators and heads......other than that have to replace freeze plugs
