It comes in two sizes and the smaller one fits my NHW11, 03 Prius transaxle pan. The larger one would easily fit on the ICE oil pan. It would take one day to install, let it cure over night, and you're done.

Bob, thanks again for the info. I will have to consider getting one of those. Do you think using the oil pan heater alone would be good, or would you suggest adding an additional heater on the block? I am just starting out, so I think the oil pan heater is a good starting point. The temperatures do get down into the teens in the winter, and usually no warmer than the mid 20's at night. Since I only drive 20 minutes to work, this would help out a lot.

Re: Summer block heater testing
The Plug-In Prius does NOT increase the available speed of EV.
There are mechanical limits that do not involve the battery.
What the plug-in battery pack does for you at highway speeds is, it takes some load off the gasoline engine.
If in a normal Prius you drive 65 MPH at 2500 engine RPM, you can now drive 65 MPH at 1800 RPM, saving gas the whole way.
Does that answer your question?

Yes no? Thanks, JJ
Thanks Bob. I have been looking for detailed info as opposed to hearsay. The graph says it all, but I do have a couple of questions. Do you have data for the "P" mode without the engine block heater? Also, what was the temperature that morning?
I'll pickup the "P" this morning. Temperatures have been running about 80F in the mornings.

No problem, I enjoy sharing what I've learned.

Except for plugins, the EV energy comes from the ICE. Our hybrid advantage is the ICE energy is handled very efficiently including storing the extra for use in limited EV modes.
You might get a kick out of this:
Same loop at a higher speed:
In both cases, the ICE and EV modes cycle on and off. The difference is at higher speeds, the peak power goes up and the cycles tend to be more ICE and less EV. But you can easily see the ICE mode charging the battery.

Yes. Thanks. I dont recall exactly but I remember reading in one the press release of higher mph in EV. I have been reading so many news that perhaps I could have mix this it up with other news. If they can go to 50 mph on EV only, that will score big with many. 40+ mph just doesn't cut it in my neighborhood.
I'll pickup the "P" this morning. Temperatures have been running about 80F in the mornings.
Thanks! Can't wait!

Indeed!
If I understood the graphs correctly, your prius runs on EV about 2 mins at 15 mph and 1.5 at 30 mph. That corresponds to only 0.5 and 0.75 miles respectively. Hmm.. I dont have nav on my TCH so I only rely on the analog consumption gauge. I am sure I can get the TCH to stay at the E mode for much longer than that at 15-20mph. Hmm..could "E" represents something else other than EV? Thanks.

I won't be able to do good energy loss testing until cold weather returns to North Alabama. The priority should be engine first followed by the transaxle. Getting the vehicle into hybrid mode so it shuts down the ICE at every opportunity gives the greatest improvement.
There are Dept. of Energy and Toyota SAE reports about transaxle losses that trace directly to the transaxle oil. Based on these reports, I've looked at the transaxle oil and operational temperatures. One safe thing to do is to bring the transaxle up to operational temperatures. This preheat brings the transaxle oil to thinner viscosities instead of robbing power from the drive train to warm up the oil: http://home.hiwaay.net/~bzwilson/pri...ml#PERFORMANCE
I haven't seen the underside of a Camry so I don't know if there is a flat surface on the transaxle side for a heater. Before ordering anything the first step is to inspect the likely mounting surfaces. You might also check with Toyota Canada to see if they have a block heater for the Camry. The other thing is to consider when is the best time to install heaters. IMHO, the priority should be summer, fall, spring, and finally winter.
