Technical A top tip when dealing with fluids. This one sucks!

Hello and welcome to Mart's Garage. I needed to swap drain plugs on the big inch flatty in my 32 Sedan. How to do it without losing coolant? I remember Canadian Youtuber AvE mentioning this trick and I thought I would try it. The results were unbelievable. Really, as in I didn't believe it.
Check it out and see how I got on.

Now that is a great tip! Thanks for posting, now I’ll be checking out AvE channel....

 

Cool Mart! I want to change out the flat style petcock in my radiator to one with a pipe, like you just installed...I'll be using that trick.
