So the cooler shown above could be used in conjunction with the stock cooler? I thought that the stock cooler had to be deleted/bypassed.
No it's the same setup here, many people DO delete the stock cooler when installing the aftermarket one but you CAN also leave it in place as well.Chances are it's a different set up out in Australia versus the US Ranger. Out here we have to delete the cooler in order to add plum in what you did. Or we can wait for mishimoto to bring out a more efficient heat exchanger when you would be a good idea. It's just whether or not they're going to do it or not
