Pro tip: stop checking coolant with the cap off on a warm engine, I learned the hard way at the shop
I used to pull the radiator cap to check coolant on a warm engine, thinking it was fine if I just glanced at the level. Last Tuesday a 2013 Civic came in hot, and when I cracked the cap a little, that scalding spray shot out and caught my forearm. I had a tech at the shop in Amarillo tell me straight up: "never open it warm, let it sit an hour or use a spill-free funnel." Now I pressure test cold every time, and my arm is still healing from that 2nd degree burn. How do you all check for leaks without getting sprayed?
Man, that Civic story hit close to home. Tried the "just a quick peek" method once on my old truck and got a face full of hot coolant for my trouble, felt like a real genius standing there soaked and steaming. Now I let it sit a good hour with a rag over the cap and crack it slow, then use a spill-free funnel for the actual check. My fool self learned that the hard way too, so you're in good company.
