Hi,
I live in Taiwan and apologize for my poor English writing. Hopefully, I can describe my situation clearly and correctly.
Two months ago, I bought a used 2000 Nissan Maxima GLE in Taiwan which was the same model as those sold in the U.S. However, recently when I tried to clean IACV-AAC and throttle body, I found there is some coolant inside the IACV-AAC's auxiliary air passage and on the surface of it. I'm not sure if the leak is from the IACV-AAC or throttle body. The leak was small but I need to add some coolant every two week. I also found there were two in/out coolant hoses on the IACV-AAC. Can I just use a bypass hose to bypass the IACV-AAC? Will it cause any side effect? Will it effects warm up fast idle mechanism? In addition, if I decide to replace the defect parts, do I just need to replace IACV-AAC or both IACV-AAC and throttle body? I'm not sure if coolant will also goes inside the throttle body.
Any comment or advice is highly appreciated.
Thank you in advance.
