[mx730md]

does anyone have that block check tester where you have fluid that changed color above the coolant overflow tank around carrol or fredrick county? id like to test mine i have high pressure in the coolant system but dont puke or over heat. if anyone has it id give you a couple buck if you would test mine since in the kit you get it suppost to be plenty of fluid for multiply checks.
