cant figure out the reason nissan put the thermostat in the lower rad hose and not the upper but has any one ever put an inline thermostat in the upper rad hose were it should be? cars not really overheating but when i bought it i drove it back home 500 miles without 1 heating issue and now every time u get on it when its warm it starts to idle higher normally the car idles at about 2.5k on a ka clutster get on it and it starts idleing at 4k and gushes coolant out the rad but its not hot and i just have a 50/50 mix in it of antifreez

The Thermostats location isn't the issue... perhaps you have air.. or a clog water pump issue etc.. instead of hacking in a thermostat.. you should concentrate on finding the real issue..

^This.. sounds like you have an air bubble.

Blast the heater, jack the front end up, get a proper coolant funnel and make sure the thermostat opens and coolant circulates. http://www.amazon.com/Lisle-24610-Spill ... B001A4EAV0

They arent the easiest motors to bleed, but I wouldn't waste your time relocating the thermostat.

iv done it with a waterbottle like that but maybe ill try somthing taller but i was also thinking about going with that inline thermostat cuz its a 160 and make the engine run a lil colder but maybe its somthing in my heater core just got the fan working and even when the car is warm it still dont blow the warmest

Impossible to get air out if your constantly pumping it in.
