Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
HelloCustomer I had replaced a hydro-boost on a larger Chevy truck and found within the ports of where the lines connected, there was a check ball. Look over your original hydroboost and the new one and see if there is an item that you needed to swap over, but didn't realize needed to be. This is just a thought but it may be your ticket. Let me know if you find anything.
