DIY Radiator bypass hose removal
#22
I saw a sedan owner here do this and I did this now to mount an oil catch can to the timing cover but it doesn't fit because of the radiator shroud(I think people shave some of it off to make catch cans fit). There is also another way to do this using the DM2 method here in this thread. This is better and safer and it removes a lot more stuff. https://g35driver.com/forums/engine-...coolant+bypass Nissan has done this to make the cars emissions friendly. This has no adverse affect on the cooling capability of the car and it improves it instead.
This is only temporary for my car. I already have the coolant pipes ordered so I can weld them shut instead or tap and block them off with bolts like the DM2 bypass mod.
These caps are China made and even though they are thick I have no doubt that they will eventually burst after some time and lose someone a motor. That's why it's better to tap and weld the coolant pipes/flanges. The caps also seem to be rubber not silicone.
Anyone doing this make sure you have distilled water or extra coolant around. The only difference I noticed after doing this mod and bleeding the coolant system for more than 1 hour is that AC temp is a lot more precise now. Now there is a difference between 88F and 90F where as before I would have to go from 90F to 85 or 80F to feel a difference. I have no idea how and why this made an improvement.
Pics. Also the coolant system needs to be bled of air until the heat literally burns the skin at 90F 6"-8" away from the AC vents.
