I have a bottle of NAPA coolant test strips that I bought a couple years back when I got my IDI. Last time I went to test coolant the strips had gone bad. The bottle contained ~50 strips and I had used maybe ten. A new bottle of strips from NAPA is $40 and I was wondering if there was a less expensive alternative, or even just a smaller package that would work. I wouldn't have a problem paying $40 if I used them, but with only the one diesel engine I'll never come close to using them up before they expire. Does anyone know of any other sources or brands?
