98 Accord V6.

I suspect that I may have a slow leak in my cooling system. So after watching a bunch of youtube videos on how to pressure test the cooling system, I loaned the tool from advanced auto part to do the test. Well guess what? None of the adapters included in the kit fits. Albeit, I did change the radiator a number of years ago, it should still be within the OEM spec since the original radiator cap is still used.

I took a pic of the cap, see attached. If you know the size of cooling pressure test adapter please let me know as soon as possible. I can only loan the tool for 5 days.

 

Btw, this is the radiator bought 5 years ago if it helps to pin down the correct adapter size. Thanks.

you could try harbor freight if you got one nearby, try youtube

 

I do have a harbor freight within driving distance but I don't think I've ever seen the adapter in the store.

There are a few youtube video out there but not one specific to Accord V6. And none of them mentioned the size of the adapter either.

 

Okay. I was an idiot.

The adapter is included in the kit, I just didn't try hard enough.

The adapter size is #8, folks! Don't ever let that be a hinderance to you again.
