Anyone who has fought a seized exhaust fastener or a stuck manifold heat control valve knows the value of a penetrant that actually creeps into the threads. This is the factory chemical, listed in the Mopar chemical catalog as MP-50, and it does double duty as a moisture displacer for damp ignition components. It is the current replacement for the old manifold heat control valve solvent.

Application Notes:

• Penetrates metal fittings to ease disassembly of rusted and corroded parts.
• Displaces moisture from a wet ignition system and leaves a moisture-resistant barrier.
• Provides short-term rust prevention and protection after service.
• Meets the MS-3613 material specification. Supersedes 04318039AB, 04318039AC and 04318039AD.
• 9 ounce aerosol can. Contains hazardous material, so shipping restrictions apply.
