So i bring my car back to my workshop, jacked up high, use torchlight also cant find where the leak spot. All kind of examples i've tested (running the engine keep it hot/go out take a short ride slam RPM to 6k) is useless. Even i put on the water tank pressure pump system also cant find the leak. Actually, doesnt mean new hose will never leak anymore, there is 2 places i found leaking, but it only happend when u slam on the RPM 6-7k and car must be running not idling. Then u can see water coming out from the hose due to too much pressure (check both end of hose), especially the under hose which installed bottom left of the fan. There is a termostat sensor connected. The sensor also will leak once the pressure is there. The last part is abit difficult, u need to take out ur air filter box 1st, then u can see clearly the short hose connected to the expansion tank, at the end of the connection between the hose and tank, look underneath it ! and u might found dried water sign. wakakakkakakakkakaka.Hope this can help most of the people who facing this problem. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin    :D" loading="lazy" data-shortname=":D" />D</blockquote>
