Want to install an Engine Block Heater yourself? This guide may help.

No, nothing to remove, no oil to drain. Just find the hole. One tip, I was look for a hole that ran vertical, up from the bottom to the top. The hole runs laterally with the aperture on the left side, inserting towards the right.

Now it get me thinking if I should build a microcontroller to regulate the temp (e.g. shut off EBH when it reach certain temp)

Another (really crazy or I am nuts) idea, is to set a timer/microcontroller, use the HV pack to drive a EBH. Then you don't have to worry about plug it in, forget to unplug etc. Except it could run the HV pack dry before you start your day. But if you program your microcontroller carefully, say adding a RTC to it, it may work. Have it to fire up Mon-Fri morning. Cuz I think the HV pack may just have enough juice to run the EBH for 3 hrs to be safe. Oh but then how much ICE will get used up to recharge the HV pack? hummm... this get me thinking... hummm

Why do the words "Danger Will Robinson" come to mind when you start "thinking".
At 3 hours that's at least 1.2kW...you better make sure you've got safeguards in case you park with a low SOC one day or are off on vacation for a couple days in a row...or sick or leave it with the spouse or whatever.

I know what you're thinking, and conceptually I like it...but practically it seems frought with bad mojo.

Yes, of course... If one using HV pack to heat up the engine block, they alson need to factor in the SOC of the HV pack as well. The worst is when you only have 1 bar left, drained the HV battery & 12 V battery dry on a Freezing Monday morning. hehe...

nice sticky!

These instructions were fantastic! 35 minute install - no problem. Then we tried on my dad's Yaris - that took about 5 hours with a lot of disassembly....I wouldn't do one of those again...

On a Yaris? Has it helped on the MPG's?

Don't know yet - just installed it this afternoon. It was the same part, though the installation was upside down of the prius and we had to shave down some of the clip to get it in. That does not even consider all of the disassembly required to get at it. This is my dad's car - he is currently getting about 40 MPG...I'm talking him into pumping up the PSI on his tires and using the block heater daily. He is also buying a scan guage which will be invaluable to him without an MFD on the Yaris.

I just called my dealer in West Bend. He claims an EBH is not available for my '08.

Looks like I'm going shopping online. Anyone know who might have one "in stock"?

I just wanted to say that the guide provided by Green Hokie in the original post in this thread works for Prius Classic models too. I just installed a block heater in my 2003 Prius and had no problem. Thanks for the excellent photos. I never would have figured it out without this help.
