im running a sohc d16y7 with greddy turbokit on emanage blue on stock ecu

my hatch still havin issues thats trippin me out ever since i started boosting okay here it is,
it overheats ""sometimes"" i mean "sometimes"
its wierd then when i drive fast and it doesnt do anything.
but when im city driving after or just plain city driving, coolent will start overflowing out my resivor,

and the wierd thing is my heater stopps blowing hot air so then i drive faster and it starts blowing hot air again wdf is that and also the engine starts to cools off. but then eventually does the same thing again overheating again minutes later.

i dont know if its the heater core
or my head gasket
or my water pump
or my ecu bacause it does want to run funny when it acts up like that.
ive tried bleeding my hoses n letting car run with radiator cap off.

so i have a new oem honda head gasket ima install and arp headstuds
hopefully it should work things out but from now and i do have aluminum radiator n new thermostat works and fan works also fan switch works


does anyone have any tips on my motor build to help me fix it cause i wanna start boosting more pretty soon but this problem tripping me out n stressing me out n tired of spending more money on things thats not fixing problem.
if u can help please reply

thankx

had same prorblem ..it was airpockets in cooling u got to bleed all the air out i just parked mine on a steep hill were raditor cap was higer then heater core and leave cap open and turn heat on full blast and just keep fillin it up and u will see it bubble out just keep fill it andwhen no more air bubles coming out ur good

 

make sure ur fan is going in right direction ...ive seen people switch two wires and there fan spins wrong way ......way to check that is put a piece of paper behind raditor and see if it suck the paper to the raditor ...if it blows it away ur fan going wrong direction..

 

werd i tried that be4 it still manage to come out stil my cars got a curse hahaha

 

believe it or not your problem could be the smallest and least expensive part of the cooling system. your radiator cap. if something is wrong with it, it can cause all kinds of problems. they are designed to open, due to pressure, at a certain PSI. every PSI raises the boiling temp of your coolant 3 degrees. if it's junk it could cause your problem.

 

ima change head gasket i just hope its not water pump i bought silicone hoses tho looks dope and i bet after problems fixed gonna work sick too
but news now i bleeded radiator and guess what now theres alot of bubbles still coming up haha so we all know what that means
