Didn't exactly look like a straightforward swap, but I guess if you're good at these things it's no big deal

Honestly, It looks like a very simple swap. Its two bolts and two clips that hold the entire assembly together. It's a pain in the a** though. The rear clip is in the stupidest position and the whole project is very awkward. I did it and I had wished I payed someone to do it for me. But the CM30 but get a mechanic to put it in for you. It took me like 6 hours and I'm pretty good with cars. I've installed everything from subwoofers to coilover suspension but this project just sucked.

here is the step by step.
1 brake torque on front right tire bolts
2 jack the fron right tire with the back under the trunk floor mat
3 remove remove bolts and take tire off
4 remove the front right wheel liner and the plastic piece right under the bumper you wil see the pum located right behind it..
5 remove bolts for the mounting bracket from the old pump
6 removed coolant lines and install in new pump accordingly
7 splice the power , reconnect and mount the new pump with the provided braket that comes in the package.
8 bleed system put everything back together in reverse order from step 4 to step one and you are done.................. if you are still confuse after this use google search bar.

The problem was I couldn't remove the stupid clamps from the hoses, that was the annoying part. But I'm not going to argue any further. It's really the OP's thread.

The replacement is probably one of the easiest jobs to do on the car. I think it took me a little more than 1 hour and that's doing a coolant flush, refilling the coolant, and running a heating cycle to remove air from the line. I don't think I even took off the wheel, I think I just turned it to get access to the panel. The clamps were a bit tricky and there wasn't a lot of room, but you can use pliers to get the clamps off.

Maybe I'll try it then, since I got the Bosch HD pump, I guess it should be plug and play compared to the CM30 which needs some mods to fit.
Thanks for all the tips, and sorry for hijacking the thread. I believe the OP got his answer already anyway though.

@ apox, if you are going to own this car for a long time you need to start getting used to doing the litle stuff since you are going to be doing them over and over again sometimes to troubleshoot just an advice if you have money to blow go ahead plus for me its not about the money saved its about knowing that it was done right. the only tools you will for this whole car are found in walt mart 30 dollars mechanics tool set i bought mine 7 years ago and its still holding it own till today. on this car if something is taking someone a long time to do its because they are trying to figure out how to do it

My question for you is, how can you mount it verticaly as there is simply NO room
Although I still agree with you my friend
PS: I did mine in less tha an hour as well. It really isn't that hard guys. Pain in the *** yes, difficult no.
