Pretty sure it's the opposite on my Honda.

How would the temperature be regulated by a thermostat only exposed to cooled water from the radiator?

In a closed, circulating system, is there really an "in" and an "out"? A thermostat lets out what it also lets in, no?

In and out of the engine. Both the Suzuki G10 in the Metro and the D15 in the Honda, the water pump pushes coolant into the block. it rises up and exits the head. On the Suzuki engine, the coolant goes through the thermostat before going into the radiator. On the Honda engine, the coolant goes through the radiator and then through the thermostat.

Actually Canada and the US, the household voltage is 120v. X 15 Amp = 1800 Watts. 80% is 1440 Watts. So a 1500W heater should run continuously without a problem. With the exception of the extension cords. Depending on how long and the gauge of wire in them, you will have a voltage drop through the cord, which will decrease the available continuous current.

But if you put the tank heater on an outlet with a timer, a 1 hour draw should not be a problem in most cases. The extension cord, will dissipate the heat generated, because it is lying in the snow

I also felt the coolant hose coming out of the heater this morning, and it was HOT. I'll have to get my IR temp gun and get a reading off of it just for giggles. If I was going to a higher wattage heater, I'd definitely try to mount the heater in a better position for better natural convection. Its too far off to the side right now IMO, but it was easy to install there.

The other option that I'm pursuing is an electric water pump which would circulate the coolant while the heater is plugged in. I need my garage back to finish up that project though.

Another month and another fill up. 54.3 mpg now that the weather is getting a bit warmer.

Its been a while since the last update. I lost my exhaust last Friday on the way to my in laws for dinner. I bungeed it up and fixed it over this past weekend.









And with that, and its just about time to let this car move on to its next owner. This weekend I took time not only to fix up the exhaust, but also remove most of the modifications from the car. I also got it all cleaned up. Hopefully it won't take too long to sell. Once it does, the Insight will be my new daily driver. I am looking forward to playing with it.

Did the tired old Metro do better, MPG-wise, than your Prius on your commute route?

[Daox]

The answer is yes, the Metro got better mileage than the Prius. The Prius consistently got high 50s with one tank well into the low 60s. The Metro did high 50s all day long with a few 60 mpg tanks, and a couple tanks into the mid 60s. I probably put more effort into getting higher mileage with the Metro though. It also has more modifications. It also requires a lot more effort to get that high of mileage. It'll definitely be interesting to see how the Insight compares.

Interesting factoid. Last week I was coming in to work with the Metro hitting 65-70 mpg every day. Today, without mods (and it was a good 10-15F cooler), I only clocked in 45 mpg. That is without engine off coasting, just driving it easy, timing lights, etc.

The Metro is officially off the road. I smelled gas the past couple days, but on Friday when I went to leave for work it was especially strong. I've now put the Insight on the road. More info in my build thread here:
