yeah, a bit of both. when I wrenched back in the day, grease/oil/dirt would get in the tiny cracks and crevices of the skin of your fingers. and it didn’t matter how many times you washed your hands, they still looked dirty.

> [this forum](https://www.wranglerforum.com/f202/how-do-i-bleed-air-out-of-the-cooling-system-2352283.html) discusses it and it appears there’s a bleed valve on the thermostat housing. If this is the same Jeep as yours then you might need an offset wrench to get to it.

Yep, the bleed valve on the thermostat housing is easy to open/close with a screwdriver. This [coolant funnel kit](https://www.amazon.com/EPAuto-Radiator-Coolant-Filling-Funnel/dp/B01I40ZQWE) is really cool. I didn’t spill a drop!
