overheats after a few boosts

itsjdm · 3rd July 2008, 04:51 PM

my car is overheating after a put my foot down a few times it goes just over half way what can i do to stop this i do only have a half size radiator

ITR_cam · 3rd July 2008, 04:56 PM

um check the radiator isnt blocked.. get the tank taken off by a radiator specialist or try flush it yourself with some wynns rad flush.. make sure its bleed properly also

could be thermostat not opening?

check timing?

thermostat not opening..

itsjdm · 3rd July 2008, 05:24 PM

i put a new one in about 3 weeks ago

nemesisteg · 3rd July 2008, 05:27 PM

when you say its going just over halfway, do you mean thats as high as it goes?? or does it keep rising all the way to the top of the gauge?? welcome to the joys of turbo honda, upgrading your cooling system to accomodate can open a pretty awesome can of worms

itsjdm · 3rd July 2008, 05:31 PM

it goes just over then i pull over and it goes back to half then just under half

Coupe-R · 3rd July 2008, 06:12 PM

around half is operating temp, take that gauge with a grain of salt.
Like just over half could be well over 100C.

get a decent temp gauge, and get a decent radiator and fan you should be ok,

other than that, maybe check the tune and plug heat range. It might be to retarded and heating up too much

AccordB20A · 3rd July 2008, 06:15 PM

see if it goes any higher.....

may need to check your tune. lean mixture would make it get hot.

Coupe-R · 3rd July 2008, 06:26 PM

yep, lean mixture would get hot and blow, too much igniton retard will heat it up tho HEAPS

This is why we don't advise nubs to have a turbo honda

Radiator's physical size is fine. Fan coming on at all? How high will it go?/

Remove air from coolant and/or flush it.

itsjdm · 3rd July 2008, 06:33 PM

tune and plug heat range

speed factor just did it only been driving the car 5 - 6 days since i just wont boost so much

fans on a switch might get me another

BTLF3D · 3rd July 2008, 07:12 PM

buy a proper temp gauge (hopefully it reads right :s) and see what temp it is on the gauge, also try some redline water wetter instead of antifreeze.

ITR_cam · 3rd July 2008, 09:02 PM

is the fan sucking the air through.. not blowing it back towards the front of the car

bumpd-EG · 3rd July 2008, 09:16 PM

never even got hot for me....???
it would just come up to 1/4 on the gauge and stay there all the time pretty much.
so somethings not right?

sounds like when you had it the thermostat was screwed.

Should have sat at half at operating temp, any lower and the thermostat is sticking open

Seriously check this, mine was wired backwards and it was doing exactly what you describe. Easy to do by mistake especially if youve been fucking around with the wiring and adding switches etc.

yes i also have done that and it does make your car overheat weird enough.

Why is it weird? The fan is trying to push hot air from the engine bay back through the rad and out the front of the car.

ITSJDM: You've just had a partial tune from Speedfactor, and have been playin round with the wastegate? If you have upped the boost from what you were tuned for it will be running hell lean (I would assume Lin to but a boost cut in but who knows I guess). Something else to think about.

SK1TZ- EF · 6th July 2008, 12:49 PM

I had my fan spinning wrong way, just gotta swap the wires on the 3 plugs till you get the fan taking air away from Rad, but honestly, anywhere around half should be OK (on NA Honda) if it goes higher than 2/3, be worried
