After a freezing night, a warmer engine can make the morning start easier. This Zerostart heater threads into your engine block to preheat coolant, so your engine starts with less cold-weather strain and warms up sooner.


Highlights

  • 400-Watt Coolant Heating: Works with a 120V outlet to warm your engine before a cold-weather departure.

  • Phillips & Temro Experience: Zerostart comes from a manufacturer that also supplies OEM engine heaters.

Features to know about

Give Your Engine a Head Start on Cold Mornings

When your car or truck sits outside overnight in freezing weather, the engine can take more effort to start. This 400-watt Zerostart heater warms coolant inside the engine block before you turn the key. With the engine already warmer when it starts, there's less cold-start strain and it can reach operating temperature sooner. It's a practical addition for the days when winter weather is part of your regular morning drive.

Find the Right Threaded Opening for Your Engine

This heater screws into a designated 3/4" NPT threaded opening in the engine block. Although it's categorized as frost-plug style, it isn't a press-in core plug or a dry cartridge heater. Fit and installation location vary by engine. Check the vehicle fit information for compatibility, then use the Zerostart application catalog (see instruction link B below) to locate the correct opening. The manufacturer's installation instructions linked below explain the procedure.


Plan on draining the coolant and removing the specified threaded plug. Apply pipe-thread sealant or PTFE tape as directed, install the heater, and refill the cooling system. Run the engine to check for leaks and purge trapped air before applying power to the heater. The element must stay submerged in coolant whenever the heater is plugged in.

Make Preheating Part of Your Winter Routine

The included 5' silicone cord has a right-angle connector that attaches to the heater and can be routed toward the front of your vehicle for access. Secure it away from hot and moving parts, and check that it reaches where you plan to plug in. Phillips & Temro recommends at least 3 to 4 hours of preheating before departure. Be sure to unplug the heater before starting the engine.

Know Who Makes Your Zerostart Heater

Zerostart is a Phillips & Temro brand. The company supplies engine heaters for original-equipment applications as well as aftermarket vehicles, so you may recognize the manufacturer even if Zerostart is a new name to you. Its heaters are developed and tested for individual engines, which matters when you're choosing a heater that needs to fit a specific opening in the block.

Important Notes:

1. Coolant and Installation

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, which can also shorten the heater's life. Follow the manufacturer's instructions for sealing and tightening the threaded heater. Overtightening can damage the threads or compromise the seal.


2. Testing Your Heater

Never plug in the heater before installation to see if it works. Without coolant surrounding the heating element, it can quickly overheat and cause serious burns. Instead, disconnect the cord and use a multimeter to check resistance directly across the heater pins. The manufacturer's general testing guidance specifies a reading between 5 and 100 ohms.


3. Using Your Heater Safely

Always make sure the heating element is fully submerged in coolant and any trapped air has been removed before plugging it in. 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.


4. Disconnecting the Power Cord

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 connections, potentially causing the heater to malfunction or creating an electrical short.

Video Transcript for Review of Zerostart Vehicle Heaters - Custom Fit Frost Plug Style Engine Block Heater - ZE89FR

Hi, everybody. Andy here with etrailer.com. Let's take a quick look at the Zerostart custom fit frost plug style engine block heater. Now this is going to fit a wide range of Ford and Mercury vehicles, and I do have a lot of information there for you on that graphic, but those vehicles are going to be equipped with the 3.0 liter, 4.0 liter or 4.2 liter V6 engines and select 7.3 liter V8 turbo diesel engines. Those include the Ford F Series trucks, the F-150 through the F-550, and then the Free Star Mercury Monterey, Mustang, Probe, Taurus, Tempo, and Ford vans from years 1986 to 2009. Now, my recommendation is to go through our vehicle fit guide here at etrailer.com, enter the year, make and model of your vehicle and any other questions that it might ask, and our fit guide will confirm if this will work for your particular vehicle or if we have something comparable that will work for you.

So as you know, cold mornings don't have to mean slow starts or long warmups because this custom fit block heater is going to get your engine ready before you even turn the key. By warming up the coolant ahead of time, this is going to help your engine fire up smoothly and reach operating temperature faster. So you're going to be able to hit the road without waiting around. When those temperatures do drop, engines can struggle. Thick oil, cold metal parts and dry starts are gonna put extra strain on your starter and reduce your engine's life.

So that's where this block heater is going to come in. It's gonna take care of that issue by pre-warming the coolant so your engine's going to turn over quickly, run smoother right away, and avoid that unnecessary wear rather. Now, unlike universal heaters that often need tweaking or extra parts, as we saw, this one is built specifically for your vehicle's engine. So it's going to install right in the frost plug. That's the spot designed for efficient heat transfer.

So it's gonna be a clean hassle free setup. This is gonna give you 400 watts of steady heat at 120 volts and it's gonna give you reliable warmth that's gonna keep your coolant ready to go. And this silicone cord is removable from the heater. So if you ever damage the cord, you're not going to have to replace the entire heater, you'll just have to replace the cord. So that's an added benefit here.

And also, this is a nice touch, this does come with a tethered cap here to cover up that three prong plug when it's not in use. So it's going to keep those prongs in good shape. So this is going to fit a 3/4 of an inch NPT bore diameter. If you happen to have any other questions about this heater or anything else that we carry here at etrailer.com, don't hesitate to reach out to us. We do want to make sure that you're getting exactly what you want and need. Well, again, my name is Andy. Thank you for joining me.

Fits as it should and works great.

I tested out the Zerostart engine block heater, and I like how well it’s designed for cold-weather starts. I was impressed by how solid the build is and how quickly it helps warm the engine. What really stood out to me is that Phillips & Temro actually test fit their heaters and work directly with OEMs to make sure every unit fits and performs the way it should. They’ve got a full engineering team and a cold room big enough to fit a semi-truck, where they test products down to –40°F. It’s a well-engineered heater that’s tested to fit, and that kind of quality control gives me a lot more confidence compared to other brands, like KAT’s, that don’t go through the same level of development. It’s a reliable heater that does exactly what you need when the temperature drops.
