) and always have been. But there is one thing that I have never understood. Why did GM not put the 4.2 I6 in the colorado when it came out in 2004, as it is little more then the truck version of the Trailblazer SUV? The 4.2 would have greatly improved the capabilty and both vehichles use basicly the same transmission( or exactly the same, I'm not sure ) So why did GM cut it down a cylinder and go with what is now the 3.7 5 cylinder? It doesn't make much sense to me. Can anybody else help me out?
The Colorado/Canyon are primarily an Isuzu pickup not a Trailblazer with the back cut off like the old S10 vs Blazer, it is really made for a series of 4 cylinder turbodiesel and the occasional gas engine that are put in them by Isuzu everywhere but North America
