26 Buick coolant and rear trans seal

Recommended Posts

What is good coolant for 26 Buick as I have always used water and drain in fall. Also looking for rear seal on trans. Old one looks like weather striping, can this be used? Thanks

It is a bad habit to drain the water for the winter. The block will rust a lot when air (oxygen) and humidity left reacts with the iron. When filling the engine with cold water you should always run the engine hot so that the oxygen dissolved in the water goes away.

Using distilled water in an old car's cooling system avoids the corrosive chemicals that are in tap water. And the use of propylene glycol instead of ethylene glycol gives the environment a break, as it is non-toxic. You can get it at auto supply stores (like NAPA). A 50-50 mix is optimal.
