Zerostart Vehicle Heaters - ZE22VR
- Circulating Heater
- Lower Radiator Hose Heater
- 120 Volts
- 600 - 999 Watts
- Zerostart
From job sites to equipment yards and farms, work continues when temperatures drop. This 600-watt lower radiator hose heater warms coolant and moves heat into the engine through natural circulation, helping make cold starts easier.
Highlights
- Make Cold Starts Easier: Prewarms coolant in industrial, medium-duty, and farm equipment with 600 watts.
- Moves Warm Coolant Without a Pump: Natural circulation carries heat from the lower hose into the engine.
- Check Your Hose Before Ordering: Fits 1-1/2" I.D. smooth, molded hose with a minimum 15° rise.
- Limit Heater Temperature: Built-in thermostat protects the unit at a maximum of 245°F (118°C).
- Service the Cord Separately: Replaceable cordset supports repair if the power lead gets damaged.
- Choose the Right Equipment: Intended for agriculture and medium duty engines, not cars or light trucks.
Features to know about
Start Work with a Warmer Engine
Equipment parked overnight at a job site, in an equipment yard, or in an unheated building can be difficult to start when temperatures drop. This 600-watt heater warms coolant in the lower radiator hose so heat can move into the engine before startup. It's a cold-weather preparation option for light industrial, medium-duty, and agricultural equipment with a compatible cooling-system layout. Two to five hours of preheating is usually enough before startup, depending on conditions.
Circulate Warm Coolant Without a Pump
The heater works by thermosiphon circulation. As the coolant warms, it rises toward the engine water jacket and cooler coolant takes its place. This natural movement carries warmth into the engine without a mechanical pump. For that process to work, the hose must keep rising toward the engine, with no high points or downward dips that could interrupt the flow.
Check the Hose Layout Before Cutting
This heater fits a smooth, molded lower radiator hose with a 1-1/2" inside diameter. You'll need at least 3" of straight hose for mounting, a continuous upward angle of at least 15° toward the engine, and a direct path to the engine water jacket. Check the surrounding space as well. The heater requires approximately 4" x 3" x 3" of installation clearance, including the cord connection.
Once the heater is positioned, the two included hose clamps secure it to the cut hose ends. Zerostart does not recommend this heater for automotive or light truck applications.
Protect the Heater and Replace the Cord When Needed
A built-in thermostat limits the heater to a maximum temperature of 245°F (118°C). That's a limit for the heater itself, not the temperature the engine coolant will reach. The heater connects to 120V household power through a detachable cord. If the cord is damaged, you can replace it with the Zerostart replacement cord (ZE68SR) , sold separately.
Cold-Weather Experience Behind the Zerostart Name
Zerostart is a Phillips & Temro brand, from a manufacturer that develops engine, battery, and equipment heaters. That experience is relevant when you're preparing working equipment to start in cold weather, from industrial job sites to agricultural operations.
Important Notes:
1. Verify Application and Hose Fit:This heater is intended for light industrial, medium-duty, and agricultural equipment. It fits a 1-1/2" inside-diameter, smooth, molded lower radiator hose. It is not recommended for automotive or light truck applications, and a matching hose diameter alone does not guarantee proper fit.
2. Maintain the Correct Hose Rise:
Choose a straight hose section at least 3" long. From the heater to the engine, the hose must rise continuously at an angle of at least 15° and connect directly to the engine water jacket. Avoid high points, downward dips, and sharp bends that can trap air or prevent warm coolant from circulating. The equipment must be parked on level ground during heater operation.
3. Install With the Engine Cool:
Allow the engine to cool before opening the cooling system. Drain the radiator as directed, install the heater in the selected hose section, and secure both connections with the included hose clamps. After refilling, follow the manufacturer's instructions for running the engine and checking for leaks before using the heater.
4. Keep the Heating Element Surrounded by Coolant:
Never plug in the heater before installation or when the cooling system is low on coolant. Fill and bleed the system so trapped air does not interrupt circulation or expose the heating element. The manufacturer calls for a 50/50 water and glycol coolant mixture; do not use 100-percent antifreeze.
5. Disconnect Power Before Starting:
Do not start or operate the engine while the heater is plugged in. Disconnect the extension cord from the power source, then unplug the heater cordset from the extension cord before starting the equipment or driving away.
6. Protect the Cord and Use Grounded Power:
Use a properly grounded 120V GFCI-protected outlet and an outdoor-rated, 3-prong extension cord rated for at least 10 amps. Route the power cord away from hot surfaces, sharp edges, and moving parts.

Video Transcript for Review of Zerostart Vehicle Heaters - Circulating Heater - ZE22VR
Hi, everyone. Steve here with etrailer.com. Let's take a look at our Zerostart Lower Radiator Hose Heater. It's a 1 1/2 inch inner diameter hose, runs at 120 volts, and it's 600 watts of power. So, these are great to give you dependable equipment starts in those tractors, loaders, and generators, maybe even whenever it's those cold winter months. And it's gonna protect your engine and give it some longevity because it's gonna keep that coolant moving.
It's gonna keep it nice and liquid versus getting gummed up, or thickened, or even possibly frozen, depending on where you're at in your area. And that's gonna, in turn, ease the strain on your engine and the starters and those kind of things. So, it does give you a worry-free built-in thermostat. It's gonna regulate the temperature. You simply hook this up in line with your radiator heater hose, and that's that 1 1/2 inch lower radiator hose.
And this will give you both of the hose clamps needed to then mount that. And then, of course, you have your 120-volt plug here with a nice dust cap cover, keep dirt and debris out. And this plug here is removable. I did have to give a little force to put it in, but that's what you want because you want a nice watertight snug fit. And zooming in here closer, you can see it's got about five connection points here, three round and two blade-style.
And then, of course, you have a nice gasket deep inside of here that you can barely see. But that's gonna keep everything nice and tight. And then if you need to unplug it whenever it's not in use for that season or something, it's easy to do and it's easy to replace the cord if, God forbid, you get that damaged as well or something like that. So, a great little product. This is the Zerostart Lower Radiator Hose.
I'm Steven with etrailer. Thanks for watching, have a great day.
