Hi, I'm looking at changing my coolant this evening and was wondering if anyone knows off hand what size socket I'll need to remove the engine coolant drain plug. I changed my diff and tranny fluid yesterday and was put in a bit of a spot when I needed a 24mm socket (I only had up to 21mm)) for the diff drain plug. I will be changing from green coolant to the honda type II (blue) and I really want to make sure it's changed thoroughly. Any info would be greatly appreciated. Thanks.

 

doesn't get any better than this

Yeah, I read that one. Unfortunately he didn't drain it through the plug specified in the manual. He had an engine block heater attached there and used another coolant line. I'm sure that works just fine, I was just wondering if anyone knew what I'd need to do it the "factory manual" way.
