Just a cheap checker from the parts house works as good as anything, I prefer the type with pellets that float.
I have a Prestone tester, where the indicator needle floats. I know have a Toyota, and it was suggested that I use "Japanese import" coolant (so I did). I've not yet researched the difference v. Prestone. Can anyone here give me a Cliff Notes version of an answer? And do I need to buy a new coolant tester? TIA.
The tester is the same, I only use Toyota antifreeze if it is a older model that still has Red in it. If it has the pink stuff it gets Dexcool just like everything else with long life coolant.
