Cold mornings don't have to mean sluggish starts and long idles. This custom fit block heater warms the coolant so your engine fires up smooth and reaches operating temperature quicker. Hit the road faster knowing your engine is ready to work.
Your pickup may be headed to work, or your tractor-trailer may have a load to haul. Either way, freezing temperatures can make that first diesel engine start harder. This 600-watt Zerostart heater warms the coolant inside your Cummins ISV 5.0L before you turn the key. Starting with a warmer engine reduces cold-start strain and helps it reach operating temperature sooner. It's a practical way to prepare for winter mornings when there's still work to do.
This heater is designed for compatible Cummins ISV 5.0L diesel engines, including those found in certain Nissan Titan XD pickups and commercial trucks. It uses an M27 straight-thread connection with an O-ring seal, which differs from the tapered NPT threads used on some other immersion heaters. It also doesn't press into a smooth freeze-plug opening. The manufacturer identifies the installation location at the front face of the engine, near the left cylinder. Confirm your engine's application and the correct installation location using the Zerostart catalog (instruction link A found below) before beginning.
Installation involves draining the coolant and removing the specified threaded plug. Clean the opening, inspect the O-ring, and follow the manufacturer's instructions for preparing the seal and tightening the heater. Unlike tapered NPT fittings, this connection relies on its O-ring to create the seal. After refilling the cooling system, check for leaks and remove trapped air before applying power. The heating element must be completely submerged in coolant whenever it's plugged in.
You don't want to open the engine compartment every time you need to plug in on a cold morning. The included 6' silicone cord lets you route the power connection to an accessible spot on your pickup or commercial truck. Secure it away from hot surfaces, sharp edges, and moving parts, leaving enough slack for engine vibration. Connect it to a properly grounded 120V outlet and always unplug it before starting your engine.
The cord is removable, so damage to the cord doesn't mean replacing the entire heater. This model uses a Type K connector, and the Zerostart 6' replacement power cord (ZE99SR) is available separately.
Zerostart is a Phillips & Temro brand. You might recognize Phillips & Temro from factory engine-heating applications even if the Zerostart name is unfamiliar. The company develops and tests heaters for original-equipment and aftermarket applications, including diesel engines used in pickups and commercial equipment. That experience matters when you're choosing a heater that needs to fit a specific opening in your engine block.
Use a 50/50 mixture of ethylene glycol antifreeze and water. Never use straight antifreeze or a mixture containing more than 65% antifreeze, as this can cause the heating element to fail prematurely. Avoid stop-leak additives. This heater uses a straight-thread O-ring connection, not tapered NPT threads. Inspect the O-ring and sealing surface before installation. Lubricate the O-ring with antifreeze, liquid soap, or silicone grease as directed. Never use petroleum-based lubricants, which can damage the O-ring and cause leaks. Follow the manufacturer's instructions for tightening the heater. Overtightening can damage the connection or compromise the seal.
Never plug in the heater before installation just to see if it works. Without coolant surrounding the heating element, it can quickly overheat and cause serious burns. Instead, disconnect the heater from power and use a multimeter to check resistance directly across its electrical pins. The manufacturer's general testing guidance specifies a reading between 5 and 100 ohms.
Always make sure the heating element is fully submerged in coolant and any trapped air has been removed before plugging it in. After refilling the cooling system, follow the engine manufacturer's procedure for purging trapped air. Always unplug the heater before starting your engine. Running the engine while the heater is plugged in can create an air pocket around the element, causing it to overheat and fail prematurely. Connect only to a properly grounded 120V outlet, using a 3-wire grounded extension cord if needed.
When disconnecting the heater from your extension cord, firmly grasp each plug and pull them apart. Never yank on the cords themselves. This can damage the electrical connections, potentially causing the heater to malfunction or creating an electrical short.
