Factory cooling system hoses are held in place by spring tension clamps that are incredibly stiff and awkward to remove. Standard pliers will slip off these clamps, sending them flying or pinching your fingers. Hose clamp pliers are designed with grooved, pivoting tips that grab the tabs of the clamp securely. Professional cable-operated models allow you to squeeze clamps located in deep, inaccessible areas under intake tubes or radiators, locking them open so you can slide them down the hose.

Spray it with penetrating oil and tap the tabs gently to break the rust seal. If it is completely seized, you may need to cut it off carefully with a rotary tool.
