Hey Scotty, I bought a 93 s10 with a 4.3 with only 138k miles. I have proof that I'm only the 3rd owner and both previous owners kept this truck well maintained with most service records and the car runs like a top, my only issue with it has been with the cooling system. When I made the purchase my uncle had screwed the radiator cap incorrectly. One of those lever caps, it caused the water to leak out from the cap, but luckily I didn't have to drive far and got it filled back up without any trouble for months when the heater core started leaking in my cab, I promptly changed it out and ran multiple flushes and back flushes with and without cleaners (didn't like the idea of corrosive liquid in the engine or radiator) but got most of the nasty corrosion and rust flakes out till I got clean water. Since than, maybe 4 or 5 months now, I've had 50\50 coolant in only without any leaks. My biggest pet peeve from this whole ordeal is that I can't seem to get ,1 my temp gauge to read correctly. 2 rare times when gauge reads too hot. I've changed the temp sensor sender, the sensors connector as well as 1 break in its wiring harness that was rubbed off from valve cover. My best assumption is that my gauge itself is broken because I've put an IR temp gun to it AE-LOT all over the engine it reads below what the gauge reads. Like, most every time it's hovers around 190 via temp gun. When cars at running temp gauge always is above 210, occasionally creeping up enough to flash the check gauges light. It's very frustrating to not really know what the water temp is while I'm driving, but I've put over 3k miles on it myself and ,after addressing heater core and flushing, have not had any water leaks, or anytime where the car started dying from getting too hot, it's not showing any signs of over heating but my heart drops when the check gauges light comes on and it's reading hot. Any help would be appreciated, thanks scotty

first, put on a real temp gauge, you can buy a racer type one and wire it on top of the dash easily, costs very little. then you know the real temp
