I dont see any white smoke from my exhaust, nor are there any leaks under neath the car, when i opened my radiator cap, it was clean, no clogs or any type of debris, when i turned my car off i heard some water splash sound coming from the drivers side, no clue what that was...

 

maybe be its a leaking radiator......

 

Where could the radiator be leaking from? i don't see any leaks on the ground in the morning or anything, fluid is just backed up into my reserve and causes the car to overheat... It seems like coolant is not flowing through properly or as fast as it should be, they needed to make the cooling system more bigger for these cars, ive seen soooo many heat issues about this car, the heat is working fine when i burped the air out but stopped after a while, i just hope its seriously not the head gasket, i guess that stuff is worth a try even if there is a small leak

 

I had the same issue which turned out to be a recall on my fan motors so i would investigate and see if the radiator fan are spinning properly. Please dont use top leak either that **** is garbage. But i dont think you have have any damage to the head gasket yet but i wouldnt drive the car either becuase your creating more damage. Start the car up in the drive way and let it idle for at least 10-20 minutes and see your fans kick on at all and if they dont your going to need new fan motors.

 

I had same issue as well...replaced the fans and it has been running good as new!

 

Im having a very simliar issue, will that still cause the coolant to backup in the reserve? and i left my car on, the fans did turn on, after 13-16 mins when idle...temp gauge goes up when giving gas or pressing hard on it, fluid spills out the reserve when backed up

 

I would do a radiation coolant flush and would change the thermostat which are both very cheap for starters. Make sure both fans are spinning fast also.

 

this **** is a nightmare. i just replaced the thermostat with a brand new OEM one with the gasket... i dont see any leaks on the ground at all...i dont know what else to look for... im looking for shops in my area that actually know how to do pressure test's and to check if my headgasket is bad or anything, i havent changed my fan motors yet but i just dont wanna throw money if i dont know what the problem is... could it be a bad water pump, i ran my car today after i poured very little of that sealant stuff by blue devil, tried to bleed as much air as i could and i felt a little heat back in the car, dont see no smoke from the exhausts and don't seem to be losing oil...

 

i bet its your fans

 

My fans do work, they both come on and spin at the same time but maybe you might be right, cuz fans are really whats cooling the engine when its hot, idk how they could be defective but, any good online places to purchase it from? Recommendations?

Another question... the fan and motor come together with the assembly or you have to purchase them separately? check this out

You can purchase the assembly w/motors, fans and shroud or just 'a' motor or just 'a' fan blade....simply depends on what you need. Your link above tells me it's just a single motor.

This is the fan motors, blades, and shroud for the Nissan 350Z or G35.

This is the Fan Motor found in either position of the electric fan assembly on all 350Z's and G35's.

This is the fan blade found on all 350Z's and G35's.

The recall was just on the fan motors correct so I wouldn't need to replace the whole assembly, just the 2 motors? I'm passed the warranty so I can't go to the dealer but its just plug and play for the motors? Is the replacement hard?
