rx7 FD3S Coolant Drain Plug Washer
 

Hi Guys,

So i drained the full system, removed the engine block drain plug. My question is does this have/need a cooper washer.

Its back in and not leaking but should it have a cooper washer, if so what size do i need to buy.

Purchase a 150 piece kit, figured its best -
Will post what size it is for future reference if anybody needs it :D

I think stock there is a small aluminum crush washer on the drain plug. Most times it's stuck onto the plug and is pretty well reusable.

But, it's worth replacing. Definitely post up if you find a good size for that crush washer.
