Nope....there is a cartridge type block heater that fits into a cylinder like depression in the engine. The heater clips into place - the same part fits several Toyota models and costs around $100 Can at the dealer. Do a quick search on this forum, there are other posts about it.I have one in my 05 hatch back that came with the car. It is located on the back of the block the area close to the firewall. I have thought of using the type that connects into the radiator hoses. They circulate the water.I will take a closer look tonight. I know that to install a block heater you have to remove one of the frost plugs and install it in the hole in the block.
It's just a heating element in the engine block. It might make the occasional click noise, but should be pretty quiet. If you're not sure if it's working, carefully touch the area in which it is installed after you've had it plugged in for a few minutes.is this block heater extremely quiet, because I recently purchased a 2004 Toyota Echo, and when I plugged the block heater in, it doesn't make any noise. I am wondering if it's even working.
