Benefits of a Heated Engine

Start your engine easier and warm your cab faster in cold weather with this circulating tank 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.


Circulating Tank Heater

This external tank heater connects to both your heater core hose and engine block drain as an effective way to heat your whole coolant system. The heated coolant pushes the cold coolant through the engine block, heater core, and radiator, and then thermosiphons it back to the heater. The heater's internal thermostat automatically shuts the heater off at 175 degrees Fahrenheit to keep the coolant at an optimal temperature, which allows it to heat safely overnight. As a result, your coolant system will be preheated for a smooth startup, your cab will heat and defrost faster, and you won't have to worry about frozen hoses.


Installation

The included fitting lets you attach this system to your engine block drain. If there is no drain in your engine block, then you can use a lower radiator hose connector (sold separately) to splice into your lower radiator hose instead. The included Y-shaped tube will connect the tank to the heater core hose that leads to your engine block, water pump, or manifold, depending on your application.


For the thermosiphon to work correctly, the tank must be positioned vertically. Use the included mounting bracket to secure the tank to your vehicle's frame rail, fender, or firewall. Once the tank is mounted and all lines are properly connected, run the power cord out through your grille so that it can be plugged into a 120-volt outlet or extension cord.

Review from a similar Circulating in Vehicle Heaters


Here is a photo of the engine warmer installed in a 1996 CK-3500 Chey Silverado 1 ton crew cab - Vortex 350 V8 engine. I had already installed one of these, so it was a bit easier this time around. It is a very tight fit, but worth the effort because it really makes a world of difference starting the engine out here in the Wyoming winters. Because I am a Fireman, the need for me to just go when called is paramount, and this unit makes that possible even when the temps are below zero. Thank you for having these available, the auto parts store where I bought the last one no longer stocked them. I am very pleased that it came right to our ranch via UPS too. This makes life so much easier. The website, the availability, the price and the shipping were all amazing. I will let everyone know about your company. All the way around,... 5 STARS ! Thank you very much. 465155


Comments
Still works great. Also know that I took the other unit apart and discovered the electrical contact points were corroded, so I cleaned them and now it is working fine also. Thank you for this very reliable and sturdy product. I will buy more of them as needed and I already tell other mechanics about them.

Ask the Experts about this Kats Heaters Vehicle Heaters

  • Will Kat's Heaters Circulating Tank Heater Work on 2003 Tacoma with 3.4L V6
    I spoke to my tech contact at Kat's Heaters and he confirmed that many owners of vehicles such as your 2003 3.4L V6 Tacoma are using the Circulating Tank Heater # KH13100.

  • Does the Kats In Line Lower Radiator Hose Coolant Heater Circulate the Coolant
    Kat's lower radiator hose in line heater # KH16500 does not circulate fluid with a mechanical pump. It is just a heater that operates on the principal of thermosyphoning. It will definitely help keep the fluid warm at 600 watts power but it will take it a longer time than a unit with a mechanical pump. For a true circulating heater with a mechanical pump you could use # KH13100 for 16 to 25 quart systems. If the vehicle has a higher capacity than 25 quarts we do have heaters for the...
