Hi Rem,

The only option I have for a heater for a 2012 Suzuki Grand Vitara with the 2.4L engine is the Kat's Heaters Handi-Heat Magnum Magnetic Heater part # KH1190. This heater must attach to a metal surface since it's magnetic, so you'll need to stick it to the lower section of the oil pan (bottom sump portion where the oil settles) that is made of stamped steel and make sure the heater is flat against the pan. The heater puts out 20 square inches of heat to help warm fluid in the engine block, keep the oil from thickening, and warms the transmission fluid so starting the car is less harsh. It plugs into a standard house 120V outlet with a three-prong plug and will of course need to be removed from the vehicle before driving.

How cold does it typically get where you live?

Thank you for the response Claire! I am looking for a direct replacement block heater that is currently installed in the vehicle. It is a thread on type element. It can get up to -30 degrees celsius here in Winnipeg, Manitoba Canada.

@RemM Do you know the model of the current one you have? When I was researching an engine block heater for your vehicle all the info I found said that there isn't a threaded heating element available for the 2.4L engine, only the V6. Apparently the 2.4L engine in the 2009 and 2010 Grand Vitaras were notorious for cracked cylinder blocks and unexplained coolant loss so many engines failed and were replaced. It's pretty common for the 2012 Vitaras to have a replacement engine that could be an older model that might have a threaded freeze plug or threaded coolant port, so I wonder if that's what you're seeing.
