Benefits of a Heated Engine

Start your engine easier and warm your cab faster in cold weather with this cartridge-style engine block heater. Heating your engine coolant keeps it from thickening and freezing, resulting in more reliable start-ups and smoother operation altogether. It also lessens the workload and extends the life of your vehicle's battery. And because starting your engine when it's warm creates less condensation in the engine block than starting it when it's cold, your engine will get better initial fuel vaporization, which causes fewer emissions and less pollution.


Cartridge-Style Heater

This cartridge-style heater simply clips into the cavity of your engine block. There is no need to remove the core frost plug. The power cord on the heater is removable so that you won't need to buy a whole new heater if the cord gets damaged. The cord can be routed through your grille for easy access to a 120-volt outlet or extension cord. Make sure the heating element is fully submerged in the coolant before plugging it in.

The product wasn't a proper fit at all for the vehicle. I had to modify it by cutting the thickness on the plug end with a hacksaw, to go past the engine case edge. Created a flat spot. Otherwise it wouldn't insert properly into the cavity in the engine. It would have to be all one diameter if designed properly. Not sized or designed well. Now that it's installed it seems to work ok.



by:

Had to modify it to try and get this to fit as other people showed. Wouldn't fit and because it was modified it can't be returned. It would fit but you would be taking apart the engine cooling system because of rigid metal tubes and their brackets would have to be modified as its right infront of the hole, just to fit this into the slot of the block. Not worth the effort or time unless you want to pay a large amount of money to get someone to install it. Or if you have all the tools and a lift to install it yourself, since you will be going from underneath as well as above.

2015 Hyundai Sonata 2.4 install. Have to remove air intake, very tight to get it in just enough space. Had to trim a little bit to make it fit but nothing ever fits perfect. Picture say it all.

I live in northern Ontario, Canada. Average temp is -20 but has gone as low as -30/-35. This heater was installed in a 2016 Hyundai Elantra GLS 2.0 engine. Installation was easy once the battery box was removed. Slipped in the cavity real nice. The heater was plugged in for 4 hours at -20c. I then tested the engine for warmth. To my surprise the engine block was warm to the touch and the snow had a small circle on the hood where it started to melt. This surpassed my expectation, and I highly recommend this heater. Uses 350 watts per hr. That's less than a frost plug heater at 550 watts per hr. Shipping, packaging and instructions all great.

This heater is by far the best thing since sliced bread. This little heater will keep the engine warm to the touch at any temp outside. Still working great after one year.

I cannot rate the product (which may be really fine) since there is no instructions given on installation so I'm stalled. Well the so called "instructions sheet" says to put the heater in the "cartridge" but doesn't give the slighlest idea where it is other than stating that for my car its situation is " LF" whatever that means.

Not on par with etrailer's business practices !

I recommend watching the engine block review video that I have linked below. The 2017 Mitsubishi Outlander has a transverse engine which would be mounted perpendicularly to the direction of travel, lying horizontally within the engine bay. You can see a diagram that shows the locations of the holes on the engine in the link below. The LF stands for left front.

Still working like new. Im still very pleased with my purchase



by:

Fits like the factory one. The only issue I had is that the electrical cord is a bit on the short side. Other than that the heater works great.

Jonathon at eTrailers help me verify this product would work in a 2013 Hyundai Santa Fe AWD 2.0T.

Installation was done by a 3rd party for about $100.

We've had days of -20 to -30 C weather a few times now this winter. Works as it should.

The heater worked good, finding out where to install it was difficult. It did not go where the manufacturer stated even after calling for help. Found the location using a flex line camera. Had to remove parts from the engine to install. Car started in 20 below weather several times, used a timer to turn on when needed.
