This is a great point, John. We all want our animals and the wildlife around us to remain safe. Now I don't make a habit of drinking antifreeze, but I have the occasional "splashback" incident where some winds up in my mouth...and I can say definitively that Zerex adds a bittering agent to their Dexcool concentrate. It does not have the sweet taste of older blends from years past that have killed so many animals.

Good timing on this comment, haha. I actually just changed the coolant filter for the first time since the install and initial swap (I changed the smaller filter out after about two weeks just to let it catch any junk that may have been in the coolant, so the bigger filter I just changed had been on there for about 2 1/2 years). Zero issues - the valves worked perfectly, no leaks anywhere, lines are in great shape, coolant still looks brand new. Two thumbs up!

@AllThingsMech sweet. I have a small Crack on my overflow tank and a little play in my water pump, so I wanted to do as much as possible the first time. Any other recommendations 🤔 and how did you settle on a filter bypass pressure

Not much additional to add, sounds like you've got it covered if you're replacing the pump and the overflow tank. You may want to flush the rad while you're at it depending on age/mileage and how much gunk there is in the coolant, but that's about it. I can't take credit for the filter choice, I just took the internet's recommendation and ran with it, lol. These are coolant specific filters though, so there's no bypass or anti-drainback diaphragm or anything like that - just a straight in and out design to maximize flow and help avoid pressure spikes. Once the install was complete and the engine was up to temp, I made sure to check that the hoses on both the input and output sides were hot just to verify that I had good flow and no obstructions, and it was fine. It's been a solid setup ever since. I will say that it looks like I've got a crack developing near one of the bolt holes I drilled to mount the filter, but that was probably because of the rough roads out at the ranch beating that thin sheet metal to death. Now that I'm living near pavement again it hasn't gotten any worse, so I'll probably let it ride for now...even though I should probably stop-drill the crack and weld it up. 😂 Good luck, give me a holler if you have any other questions.

@AllThingsMech so I've figured out what I'm gonna do... the upper radiator hose gets an inline coolant filter with the clear housing, and the lower radiator hose gets the filter to collect everything and to not be as hot at the inlet side. With gravity working for the filter but against changing it, the shut-off valves will come in handy. Thanks, dude. I'll even try to record it as my first youtube video for people to critique and advise.
