On the IS250 if I wanted to change the radiator, do I have to completely remove the front bumper and the impact bar and stuff just to remove the radiator? Is it not possible to change radiator with bumper and things still on?

 

The way I looked at it last time. I think you would just remove the radiator top support. Being careful as there is wire looms underneath.

 

I have done the done the radiator on my car. You should be able to remove it without taking off the bumper. The bottom radiation supports were kinda hard to reach but I was able to do it from the bottom of the car. Overall, very straight forward process.

 

I just replaced the radiator and water pump w/ help from my friends a few months ago and nope u don't need the remove bumper, but cover your bumper with something to avoid scratching the paint...
