I don’t know anything about cars/trucks other than that I like to drive them at questionable speeds. My truck was leaking coolant like a bitch. Thought it was the radiator, took it to my uncle and he found one of the hookups had a hairline crack in it.
When the system pressurized that thing was shooting out a stream of coolant.
$45 for a replacement all steel part (OEM is plastic), coolant flush and I’m back in business.
Oil change too for the old girl. Since I’m dumb and ride around on 33’s I can crawl underneath without jacking it up lol
