CROSS SENSITIVITY
TO AUTOMOTIVE CHEMICALS
Some automotive solvents and chemicals have similar hydrocarbon properties as
R-134a and may elicit a positive response (<30 seconds) from the PROWLER. Before
leak checking, clean up any of the following chemicals that elicit a positive response:
• Rain-X windshield Wash Fluid
• Ford Spot Remover (wet)
• Ford Rust Inhibitor
• Ford Gasket Adhesive (wet)
• Loctite Natural Blue degreaser (diluted)
• Ford Brake Parts Cleaner
• Ford Silicone Rubber (uncured)
• Motorcraft Antifreeze heated to 160° F
(PARTIAL RESPONSE)
• Gunk liquid wrench
• Ford Pumice lotion (with solvent)
• Ford Motorcraft brake fluid
• Ford Carburetor Cleaner
