This seems... odd to me. The motor in your prado IS a jetta engine is it not? There must be some differences, but not sure what they would be. Different year? Glow system does not work the same? Or?That's one (of many) things that I miss about my '97 Jetta. I started it a couple of times at -18ºF, no trouble at all. I was lucky to get my Prado started yesterday at 0ºF, it refused the morning before at -11ºF.
