I would think that being he is in So Cal it may get to 140 degrees or higher, depending on if hes parked outside, in a garage and his lows are above freezing and how long its plugged in for.

On mine when its about 5-15 it gets to ~70, above that about ~80-90... I only have it come on for 90 minutes... enough to help, but not enough to effect the power bill.

I plug mine in as soon as I pull in the garage (never gets below 50 in there) and unplug aprox. 12 hours later when I leave for work. This morning the attitude said 135 when i pulled out.

I took a block heater out of a motor to test it one time... left it plugged in on a bench... almost burnt the shop down 
they get very hot, hot enough to boil water for sure.
tks,

For all the guys that leave them plugged in overnight.. one question.... does it sound like a dry start in the am?
I ask because the warmth will allow the oil to drain compleatly into the pan, were (unless you have an oil pan heater) it cools... so now it wont flow as well... seems to me that one would only want to plug it in the minimum time.... 100* block and 15* oil just seems like you could have issues.
Now I know in the summer your block can be 70-100 just from ambient, but so is your oil....

When it is installed, the large thermal mass of the coolant and block will prevent it from ever reaching boiling. The temperature that your workbench will reach is another matter altogether. Good thing it was an almost.
