hello tranky that the pump mounts to your 147? cp1H R60? R65? these pumps on the 147 they kinda suck, I could not tell you why the same pump on a 159,croma,G. punto,bravo,etc...the 1.9 120cv don't cause problems I don't know...
if you need to replace, I would recommend you to go directly with a pump 2,4 cp1H R70, or you may revise your installing the cam and pistons 2.4 to the interior of your however it takes a good pompista and a little bit of money...
