Well my radiator started leaking at the plugs and some other locations so I purchased a new one, but I was wondering which plugs I need to buy.I was able to find the standard radiator plug but I couldn't find the one I pictured. Any help would be great

 

Who did you buy radiator from? So of them have a stop valve in there that doesn't require a plug. An aftermarket I bought did that and I was really concerned to not plug the hole... But they told me I didn't need it plugged so I didn't bother. Didn't leak...

 

The only thing that could be on an SC radiator is a coolant temp sensor. I encountered this when swapping to a Supra TT radiator but to my knowledge the SC300 did not have this sensor on its radiator. I have heard that SC400's do but I cannot confirm that. On the Supra TT it is an M16-1.5 drain plug size. For an SC400 radiator I have no idea, never having seen one personally.

If it's not a coolant/radiator temp sensor then I am at a loss.

 

I bought this one

They said it typically doesn't come with one but I can go to a store and find it. I've gone to advanced and auto zone and no one can seem to find it.

Well on the oem one it's just that plug. That was one of my leaks

 

Anyone know where I can find it?

 

I went to Lowe's bought a 14mm 1inch bolt and plugged it up with some Teflon tape. Stuck there like glue.

 

Thanks grumpi. I'll probably end up doing that
