I recently bought a Mishimoto Aluminum radiator used on the forums, and the guy who sold it to me did not give me the drain plug for it. I figured out that the dimensions for it are: Drain Plug Thread Size: (M16) .06", Drain Plug Thread Length: .047", but i have no idea where to buy it? Does anyone know where I could get one? Thanks

 

you should be able to get one from Mishimoto or one of their dealers, quite honestly it is just a metal bolt which uses teflon tape to seal it, get a bolt of that size and length wiht the right thread pitch and use teflon tape. The one they give you is a magnetic bolt but I see no use in the magnet as everything is pretty much aluminum within the engine and rad system. Go easy on tightening so it doesn't strip out the aluminum threads.

 

How do i find out the size and pitch? I took those diameters to three different places and everyone told me that that wasn't enough info to get me the bolt i need?

 

well you will have to guess , bolts are pretty inexpensive, if you know it is m16, then it will likely be 1.25 or 1.50 pitch I think, so try buying bolts in the right length that are m16 x 1.25, or m16 x1.50 as good places to start. If your radiator isn't installed yet take it with you to a fastener shop and try out some m16 bolts and see what fits. Find a good specialty fastener shop in your area. I would go with a stainless steel bolt as well if you can get them in the size you need, if not then get what you can and remember to use teflon tape on it.

 

Great, I will try that. Thanks JFUSION!

 

mishimoto will send you a new one. contact them directly. they took care of me quickly when i need the adapter for the temp sensor.

 

How long did it take them to ship it, and did they like charge you something rediclous for the adapter you needed?
