I have 1999 bravada that has had an engine replacement 3 years ago. I tried to get to the bolt that holds the cooler line to the oil pan and I cannot figure out how people that have repaired these have done it. Do some parts need to be removed? I was thinking maybe the diffficulty is due to the new engine.Any suggestions?

 

Been covered in the past. Use a few long extensions and a swivel socket on the end. It is a 10mm bolt. It is possible to get it disconnected. The trick is getting the lines out of there once you get the bolt out. Sometimes they come right out. Sometimes you have to jack the motor slightly. And in extreme cases you have to disconnect the motor mount and jack the motor.
