Under Hood Fluid and Filter Checks

usually, you know, I'll get up in here and I'll inspect it to see how dirty it is. I'll check the air filter. I'll pull the air filter out. Um, see how bad that is to see if somebody's been taking good care of it. Check the dates on the battery. See how new those are. Cuz for a big truck like this, it's like 700 bucks for some batteries. So, if you can get that taken care of before, I would have. Then, I always, you know, you check the training fluid when it's running and hot, you know, on a level surface. But what I always do before I run it is I smell it because you can always smell if it has like a burnt scent to it. Look at the color of it. Is it brown or is it red? This one hasn't been changed for about 40,000 miles. This is a solid transmission. You can see it's nice and red. It doesn't have a burnt smell to it. And then I do the same with the oil. Before I even run it, I check the oil level to make sure that it's at proper height. You know, that's perfect right there at the top of the line. This truck is a little older. It does have a little dirtier of oil. I smell that, too, to make sure that it smells good and doesn't smell burnt out. Okay. Like somebody's been running it hot. Yep. You know, what about the radiator? Do you look at the radiator fluid at all? Yeah, you can. And you can check for milkiness on like the top of the cap and stuff. You can check for milkiness up there. So, you're looking when you say milkiness, you're looking for a froth right underneath the cap. Yep. And then I also check on the oil cap right there as well too to see if there's any frothiness on there, which sometimes in Minnesota you get a little condensation up there from the hot and cold. So, you get a little bit of it, but a little bit isn't bad. You can also check right here too for the radiator fluid for, you know, antifreeze to see if there's any milkiness going on in there. Are you uh ever going to pull the oil uh the t the cap for the oil and run the engine? Yep. So that's what I would do when it's cold. And on big rigs, this is a
