TOPIC: check for overheating

Do the infrared laser targeting thermometers work to check engine temps or do I need to use the melting crayons? Thanks!

Yes, love mine I can check each cylinder alone and the temp of the stream

Thanks. Any old brand?

I got mine from harbor freight for 25 i think, i got it for checking tire temp across the tread to adjust pressure for autocross, i use it all the time now even for cooking
