I have an OBD2 d16y7 with an OBD1 intake manifold, and Obd0 throttle body (for vacum) I just swapped it into my EF hatch

whenever the car idles, it overheats, when im driving around and givin it gas, its fine

i replaced the thermostat, changed the radiator, and changed the hoses

whenever the car idles for 3 - 5 minutes, the overflow container starts boiling almost and spilling everywhere

after it overheats and looses coolant, and i add more water, there are bubbles that come up (when its hot, so i dont think its the headgasket)

any help is appreciated because hopefully ill be able to fix this problem by tommorow and drive my car 100 miles


Thanks

 

help me

 

did you check if your fan is working? wat about your water pump

 

well you're not going to be idling 100 miles now are ya? you'll be fine then!

it's got me stumped. if it was a water pump, it'd overheat no matter what. you replaced the thermostat...radiator is fine.

it doesn't leak anywhere until it overheats, right? it might be a headgasket. it bubbles because it's pushing the air out of the system. change your oil, see what color it is. if it looks like chocolate milk, you got yourself a bad headgasket!

 

you have like a reverse thermostat lol

 

the oil on the dipstick is good, but yeah there is no radiator fan, but i didnt think that would make it overheat as much as it did, cause one of my friends been rockin no radiator fan for a month

 

if the fan makes a difference, ill hard wire one to a toggle switch or something tommorow b/c the wiring on mine is fcked up

 

well **** guy, that IS your problem. air doesn't flow through the radiator = no heat exchange. driving/air moving = heat exchange. put the fan on.

 

bad thermo or seems like you should bleeed your system

but...he just changed his thermostat....and the reservior is boiling over. If there was any air..it's gone after that.

also, there are only 2 e's in bleed. I looked it up. So dont try anything funny.

I would invest in a cooling fan.

Also, OP, do you have the right combination of coolant/water in there? You said you were just adding water. Your friend with no cooling fan might just be running a little more coolant blend than you are or something. Thermodynamics state that water is a better carrier of heat....but coolant raises the boiling point of water. They work together for a pretty rad team. Maybe your friend has a bigger radiator? No thermostat? There's gotta be some inconsistency there.

 

Got damn it ... why every backyard mechanic is trying to be smarter than an army of little Japanese engineers who designed this car ... how hard is to understand that there is plenty of smarter people than you guys ... and in addition if they work together they are far smarter than you ... and by their common effort they designed this car to run at it's best - WITH ALL THE STUFF THEY PUT IN THERE ...

so if by any twist of your sick mind you think you don't need radiator fan ... you prolly don't need your car too. Let it overheat ...

i just got a radiator fan wired in to a toggle switch, hopefully it will run better
