1998 blazer 4.3L
I think i need a new radiator cap.
The overflow tank is full and overflowing.
a couple of days ago i cleaned the overflow tank and then filled it halfway with antifreeze,everyday since then i
ve had to add 1-2 cups of water to the radiator because it was low. I havent seen any water on the engine or on the ground.It seemed like the water was just disappearing.
Today i checked the overflow tank and now it is completely full is completely full up to the overflow tube now.at least now i know where all that water went.
m going to get a new cap because i think this one is kaput,im leaning towards getting an aftermarket cap.The cap that is on there now doesn
t look like any cap ive ever seen i
m not sure how its even suppose to work.
It`s a thin 1/2 inch thick plain plastic cap with no spring on it.
can I get any old aftermarket cap or are aftermarket caps vehicle specific?
