What Is This That Keeps Beeping???

The shop should provide you with a gallon or two of pre-mixed “permanent antifreeze”. Try to avoid adding plain water unless it only needs a quart or less and that’s all you have access to at the time Every bit of plain water you add over time will raise the freeze point of the coolant. Also, I don’t recommend adding any full strength antifreeze you may have stowed in your old beater car.

 

On the newer trucks you should see a “hot” mark and a “cold” mark. It’s important not to fill the reservoir all the way to the cap and to fill only to the appropriate marks. I’m certain you know this but not sure about others who may happen upon this topic later.

Trucks old and new develop minor leaks at some point. The coolant level sensor in general is fairly sensitive to level drops. Sometimes you can get a pinhole in the radiator from a defective radiator construction to a piece of gravel hitting it. Sometimes a hose connection will drip slowly when the temperature gets cold like when parked overnight and the colder it gets, the more it will drip

 

And the Nation hovers with baited breath over the keyboard with anxious eyes fixed on the screen for the miracle run you are trying to undertake to save a city teetering on ruin without your delivery.

 

I had a pinhole twice in my life. One directly behind the turbo on a external coolant line. Right over the right steer well in the cabover. Makes me wonder if it was a icepick stabotage... which might be a possibility.

My second was at the El Camino here in Arkansas with the output hose from the water pump on top of the 305 V8 which happened to be where you might stick a icepick as well.

 

Yes.

The car I drove home 9 miles on steam. Lost most of it, got home before any damage was done to engine.

The truck breakdown was in the median strip of I-270 at the Shady Grove Rockville subway station spur interchange northbound. I had to cross many lanes of rush traffic on foot. It was one of the most stupid and dangerous things I ever did. (And do it twice.) I called from a land line phone up on the hill with all the offices. There was no Cell Phone in those days.

Frederick 76 shop made repairs in Maryland off I-70 I think mm 54 off the 355 road interchange.
