Spill proof cap for coolant

I’ve had this spill proof cap for many years and would like to get another but can’t find one. Anyone know where I can get one? Thanks

Wouldn’t it be easier to simply use a funnel?

I’d just get a spill-proof coolant funnel set.



I’ve had a couple of those for years. Here’s one Amazon: https://www.amazon.com/Hopkins-10101B-12-Anti-Freeze-Windshield/dp/B0000AXRH1 Just search for “spill proof antifreeze spout” and you’ll find what you want.

I have several of those both for oil and coolant. I like them a lot better than a funnel.
