Thank you "GM ENGINEERS"
for the wonderful e z to install on the production line quick connect fitting that everyone leaks and does this when you go and change it...
Just to have and spend 2 hours using a chisel and a hammer way down in the truck to fit it,and i did fix it, I used a water pump fitting out of a big block,and put a real hose on it with 2 clamps..so it will never be a problem again!!!
