I just tried to check my antifreeze strength but after I took the cover off the overflow resevour I could'nt get the hose in from the tester, there was a rubber stopper in the way or something. How do you test?

 

just take out the stopper. pry it out and then replace after testing.

 

right now the panels are so cold that I'm afaid to try to remove them so I can get at it,but thanks I thought My cap may have come apart 2004.5 500

 

Does the Factory set the freeze-point for the rad....Or is it the dealers due to the different locations all these quads are sent(U.S. and CAN.) EX. warmer and colder climates....Thanks...Caper.......

 

as far as i know they are factory set since the dealers dont fill them. i ment to pry off the insert up thats under the cap. it should be good for at least -30 below f. a 60/40 mix is good for that i think since a 50/50 is good for -40
