Overheating Question

Hello, everyone. I'm new here and new to Ford Trucks. I recently picked up an '88 F-250 w/ 40k original miles and minimal rust for $1500! The truck has some minor issues but nothing to scare me away from buying it.
I'll post some pics later.

Anyway, here's my question. I ran a few errands today with it and as soon as I shut her down, the coolant overflow...overflowed. While driving there was no indication of it running hot. I've driven it a good bit around town in the past week or two and haven't had this happen. Just wondering what to look at first or if this sounds like something immediately obvious to someone. You guys are such a wealth of f'ing knowledge, I can't stand it!

Thanks

Could it be that the coolant level when you first got it, was low enough to cause it to overheat? Obviously you probably refilled it after it over flowed. What I did after my over heating issues never seemed to go away after numerous repairs and parts. The factory gauges were actually not functioning correctly, I installed an after market set and found I was in the gold zone all the time. I dont like the ford "NORMAL" gauges because they dont give you the hard numbers. Yours might be lying to you, and you could be running hot. Drive it for a few days and see if it does it again.

O, yea if the coolant level wasnt high enough the probe might not be even submereged into the coolant. There for a false reading.

Sean, There may be a different issue that I know happens on the older trucks. Your being new to the truck may not know what it likes yet. Expansion tanks on newer vehicles deal with that. Does yours have one?

Go out when when the truck has had several hours to go cold and check the level. As long as you can see water don't add any, and check it again before you start out to see if the level stays the same. Always check it cold.

I don't mean to imply that you don't have a cooling issue but your being new to the truck may not know what it is happy with.

Just keep an eye on it and keep some water on board in case you need it.

John
