Hey guys, well I am not convinced that my coolant is fully free of air bubbles although my temps are ok. Just curious if there is an alternate way to bleed the coolant of air after installing the APS kit, as the coolant bleeding valve is removed in order to put a T in its place for the turbo coolant lines.

Thanks!

I had to re-install the bleeding valve, right next to the T, to bleed the system , to much pain to remove and re-install the joint in that T, specially in the vq35, because you need to bleed the system like 10 times to remove all the air.....

you just crack the new fitting you installed inplace of the valve. Or you could jack up the front of the car and leave the cap off just be sure you poor the coolant in very slowly to let the air escape.

Hmmmm you mean just take off one of the sides of the T fitting to let the air out or what do you mean by crack it? Cant do the jack up thing unless I do a coolant flush, coolants already in there

Spill free funnel FTW. It's how I do my APS Z.

I kept my oem "T" fitting in place and spliced the line to install the feed to the turbo. If you don't have the oem piece you are supposed to unscrew the fitting that feeds the turbo and bleed it that way. I would recommend reinstalling the oem fitting and splicing the line and reinstalling the APS supplied T

damnit... highly doubt I have that oem fitting anymore... so I can just unscrew the coolant feed line that screws into the T and bleed it that way is that what your saying Ziv?

What are the best steps to take to bleed it that way... I would assume I have to plug the braided line I unscrew, then just warm up the car until coolant starts pouring out of the T? hmmmm I dont think that will work... :0/

I read something about warming the car up with the radiator cap off and the front end jacked up to allow air to get out of the radiator easier? Truth or Lies? Will that work?

Honestly, APS' bleading instructions are perfect. So just look at the install instructions. Otherwise, check the service manual for the Z.

Had this problem before, if you want to check for bubbles.. take the radiator cap off and squeeze the radiator hoses a few times.. if there's bubbling.. then you still have air in your system.. Jack up the car with the cap off too.

I've done this more times than I care to admit. You need the funnel and you need to open up the coolant system in the rear to get all the air out. It issually takes about 3-5 heat cycles to get it purged
