I bought the cooling system test kit on Amazon (link below) to test my Volvo Penta boat engine closed cooling. It dropped by 2 lbs in 30 min.
Brought it home and decided to test my F250 pickup to see if could be a problem with the cooling system test kit. Pickup was cold but still unscrewing the expansion tank cap I could hear a hiss. So tight system there with no leaks. Pumped it to 10 lbs (got tired) and awhile later (30 maybe 60 min) it had lost almost 2 lbs.
So what to think? Cheap or defective cooling system test kit? How to test a cooling system test kit.
Return it?
