I had to get another one today as I dropped my old one in the cold & broke the plastic end off.
I know we all here in the forums have one of these and check our anti-freeze before winter right??
If not "You better call somebody"...!!LOL.. (WWE) New Age Outlaws...

Owned one once. I ended up using it to suck the oil out of my supercharger.

This year, I think Mother Nature tested my vehicles for me. -5*F with a -20*F windchill.

im pretty sure mines good too. i do have a tester or two around but never got around to it. its one of those things you dont think about till its too late.

And when its too late, boy...it'* too late!

for me the engine would be done. the guy down the street has a century i have been helping with, it has the aluminum 3.1 and my wife called the other day and said his car was overheating (when it was supercold the other day). i told her to have him take it to someone who had a heated garage so it can warm up slow. well he didnt. he said he ran it a few times till the frozen water thawed and then brought it down to me to drian and put more coolant in. it didnt crack the block surprisingly. if i tried that it surely would be done

Ya just think for $6 and actually using your new antifreeze tester....
You can avoid sounds like this when U start your car in the AM....
