I always let the pre heat cycle play out, even go through the process twice on cold (-15C or so) mornings thinking it will help ( I do not really know, though). I do have some squealing belts, though...
...I just posted a question about this to you, and then thought if I relied on the thread in question it might be better...I am looking for the electrical diagram as well.
well, I am hoping someone out there has some advice for me!
On cold starts, the alternator does not appear to be charging. The warning lights on the dash all come on, the amp meter is at zero; so headlight s etc are running on the batteries only.
after a few minutes the warning lights go out...
apparently the pats guy wanted to help me and the part was available in California or something, didn't mention it was for a RHD, but Toyota Canada cancelled the order. He said Toyota Canada does not want to deal with RHD, period.
