1. The water pump just the o-ring sudah kecut.. looks still boleh pakai lagi, or jual 2nd hand.. :4:

2. I prefer 2 x 1.5L BMW coolant. I find 1 bottle is too diluted.

3. Radiator is side cover leak, can tukar the side plastic cover if not mistaken, then can pakai lagi, keep as spare or jual 2nd hand.. :4:

hi bro, further inspection of the water pump, saw that it was changed in yr 2010. there were also some corrosion marks on the impeller. so im not going to sell it, dustbin is the answer.lol. i need to reflush the coolant, so i've another 2 bottles left. for the radiator, the bleeder nipple broke also. how ever will post more when i change the valve cover gasket and need to remove the intake manifold.

Open intake for what? CCV can be accessed without having to remove intake. Unlike my stupid N46.. :20:

saw some nuts missing at the intake manifold and the pvc water pipe. good job done by the previous workshop. i've seen couple of slugish intake manifold. so its time to remove and clean it up.

You may want to consider to change another 2 hoses below the Air Intake Manifold as well.
See item #6 & #8

Cooling System Water Hoses - BMW parts catalog

Another thing is to make a heat shield for you DSC/ABS Module.. The circuit tends to fried up cos near the exhaust manifold.

thanks bro, but i can see that these parts have been changed recently. but strangly,item #10 is missing. that of of the reason for me to remove the intake manifold and inspect it. you guys got any idea how do you make the heat sheild? thanks again

An inexpensive effective DIY heat shield. Go to Jusco household section and look for thick aluminium foil that is used as backsplash for open stove cooker. Buy 2 pcs of this foil (about Rm20.00) and then wrap around the DSC/ABS module.

ok bro, thanks. i was going thru about the heat sheild. i remember i asked a fabricater to do a heat shield for my 1jz back then. will post some pics.
