Soo just got my car back on the road after finishing the eco swap, and having more issues. Been driving aound a bit just around the block a few times, and today it starts overheating. It did at first but barely over running temps but because the fan fuse was blown soo replaced that and fans work fine, but its now overheating for different reasons. It seems like coolant isnt getting through the hoses, atleast the upper..either that or theres air in the system because when squeezing the upper hose I dont realy feel fluid but it pushes the fluid in the tank, sound like air in the system? The radiator was ever soo slightly bent from the wrecked donor car but no cracks or anything. First thing I checked was the oil but its nice and clean soo dont think its the hg.
Like said seems like the coolants not flowing through the upper hose so its getting blocked somewhere. I didnt let it overheat all the way, only went up to about 230-240 before shutting it off to cool down. Oh and before anyone asks its 42k mile motor from a running wrecked donor ca. Would the thermostat sticking be blocking coolant from the upper hose? since I can feel fluid in the lower but not upper. Sooo...
Sticking thermostat?
Coolant just need a flush?
Air in the system somehow? I know they are self bleeding which I did with cap off
Water pump?
Coolant temp sensor? But fans still seem to be working at correct temps
Any input is appreciated!
Well, anytime you put a used motor in you should always change the waterpump and thermostat. Now if ur not getting any coolant flow, I would be willing to bet ur thermostat is stuck closed. Thats really the only thing that would litereally stop it. If your waterpump was that broken you would know. If for added measure, you want too, you can put a water pump in there for added measure. Air in the system could also be a problem but it wont stop the coolant from flowing. If it got to 230-240 then its safe to say ur thermostat is stuck closed. Replace that, add coolant, let the car run till it gets warm, and it should suck down the coolant in the bottle. Also, did you check to see if you had enough coolant in the system. Ususally the way to bleed these systems is running the car at operating temp, with the coolant reservior cap off, and it will do its thing and blow the air out and fill it with coolant. And since your fan is kicking on, I dont think ur sensor is bad. Im going to say the theremostat is bad. Goodluck!
Get a 160 failsafe thermostat. not only does it keep your head from warping but you will notice just a little bit better performance.

Well, your first problem..... ECO swap
hehe
Nah, but you didn't put in a NEW thermostat when you put the motor in?
Also, like Mike said, after you put coolant into the engine, let the car run for about 20 mins with the cap OFF the resovior bottle so the air can escape.
