When it comes to leaks I tend to leave it all to the mechanics. These things are very difficult to trace unless the problem is right there in front of your eyes. As a matter of fact my van has had a slight oil leak for quite some time that not even my mechanic has been able to trace.
Usually a dye is added to the coolant in order to trace the leak/leaks and then take it from there.
#90 of 164 Nissan quest ac and engine overheating
Aug 27, 2010 (12:41 pm)
i have a 2004 nissan quest and the ac only blows cold when driving, once you sit at a light in idle the air stops working. I also notice the engine starts running hot , even to where it will overheat and i cant get it started until it cools down. Could this be my radiator fan, water pump? Where do i start, any ideas would help, thankyou email mozley44yahoo.com

You could have a couple of things going on. I would first address the "overheating" issue and have a mechanic look at the cooling system immediately. It could be as simple as a stuck thermostat. Also the overheating can do serious damage to your engine.
#92 of 164 AC / Overheating
Sep 08, 2010 (6:32 pm)
I just went through similiar issues. I couldnt get any cold air. I was in the process of recharging my ac and the engine overheated. I researched it a bit and sure enough, I found a lot of air in the cooling system. Once I bled it off the engine ran at normal temperatures. Now I have to resolve how the air got in. Your fan should be on if the engine is overheating. Mine was at full speed during the process. Like dtownfb stated the thermostat could be stuck closed. The water pump usually leaks from a weephole when it is going bad.
#94 of 164 2004 Quest - Engine Knocking Noise At 40+ mph
Dec 16, 2012 (2:43 pm)
Have a 2004 Nissan Quest. No problems all these years (believe it or not - one of those lucky ones that didn't have rattles). 107K miles.
Had an oil change recently at the dealership. About two weeks after that I'm experiencing a knocking sound from the engine above 40 mph. It only comes on when I depress the gas pedal. I take my foot off the pedal and there's no knocking.
Is that the drive belt going bad? Wanted to confirm if others faced the similar issues before taking it to a mechanic/dealer.

Any solution to this.... I'm having having the same problem. Please help. Took it to Nissan Service and they were clueless and utterly useless.

There is a Nissan TSB regarding this issue, so, any dealer should be able to find the TSB and perform a diagnosis.
While in park, if you rev the engine, to around the same RPM when you hear this noise, do you hear the same rattle?
If so, this is the known Nissan V6 engine issue with the nylon guides for the timing chain wearing out. You can fix it, by a partial engine rebuild, or let it go until the chain breaks destroying the engine (which is many many miles down the road from initially hearing it). This effects all Nissan VQ35DE V6 engines of the early to mid 2000 MY's.
