Just wondering if anyone knows a good place to buy a block heater for my 06 4cyl. Would the install require a drain and fill of the coolant?
There are a few existing posts on the RAV4 block heaters.
These heaters are cylindrical heating elements that slide into a hole pre-drilled in the block. So they're not like tank heaters...no messing around with coolant, or any fluids.
What's not mentioned in those posts, however, is that apparently Toyota recently stopped selling block heaters, at least for the RAV4 engines. That same model block heater is used in about half the Toyota engines, too. I tried ordering one online and they told me you can't get them any more from Toyota. (Weird!) A parts person at my dealer told me the same thing a few months back.
However, when I called to get my ToyotaCare maintenance scheduled about 6 weeks ago, on a whim I asked the parts person about it and they said they DO install block heaters, but they're aftermarket. Fine by me! So I got it done. I've already used it a couple of times. It may be that only certain dealers will do it, given the aftermarket nature of the parts.
Below are two of the more relevant previous posts. More detail about the overall system and procedure are in the first one (albeit for the V6 engine), with the I4 engine-specific additional info in the second one.
