What radiator options??

[markismaximus]

By switch are you referring to the one which controls the thermo fan, if so this is working, as I just tested now, it opens up and turns off like any other car.

Yes, one of these switches is temp switch. How did you test it?
Put it in hot water? and check that the switch was "on"?

Then there is the gauge temp sending unit. This is what may also be stuffed.

I'm stopped overheating with the following changed

Motl 15-50 (was using Edge 5-30)
Castrol mixed 20-30% (was using Honda OEM)

Not one overheat since!

About a month now heavy driving

Basically, switch was on, plug for it wasn't connected properly, was like wtf why isn't thermo fan working? Connected it and thermo fan starts spinning so I'm pretty sure its working.

I don't believe the heat gauge is faulty, as the car actually does get hot!

I am now believing that my issue is flow related. I believe the is something restricting flow within the system, whether it being a stuck open thermostat to faulty pump to headgasket to split hoses (but not losing fluid). So flow is the problem now

HMMM!!??!!

When the car is overheating is the thermofan running constantly? or does it turn on and off as if the car was a normal temp?

[fromdeeeast]

Na it isn't running constantly on, it turns on and off

I just changed my oil 2 weeks ago I am using Nulon 10W-40, the gold bottle.

As far as I know this is suitable for the turbo integra

Or not?

Check the radiator fins for any roadkill

that's why I say check your temp gauge sender/ gauge cluster. If the fan isn't running constantly your car can't be overheating. Or it would be running permanently. Just because the temp gauge says it is overheating if the fan isn't running permanently how can it be???? does that make sense


this is for a DC2 should should be the same I would imagine. Check it if you have a FSM

[fromdeeeast]

Sorry I must have not been thinking when I answered the question, the fan works as any other car like round town, it turns on and off but on highway when its hot it is always on.

In regards to the sensor being faulty, how could the sensor being faulty only occur on the highway and not around town.

I will check it tomorrow, With the radiator fan, fins are gone!! All broken, lol

Will replace tomorrow. Should be a productive day

- Take out thermostat
- Run without thermostat to see if water pump is working
- Replace new thermostat
- Replace rad fan

See how it goes from there, I am guessing its a flow related issue. So if not head gasket will get looked at.

Update

Have done all of the above

The water pump is working perfectly.

I installed the new thermostat and thermo fan and they both seem to be working.

However the car still overheats.

I think I might have installed the thermostat incorrectly? But it seems to be working as it should car heats up, thermostat opens, bottom rad hose gets warm, fan turns on.

But when I took it for a drive it overheated as it used to on the highway

So now what do I do?

I am considering running without a thermostat to see if that helps. Only question is running without a thermostat would that still cause the thermo fan to turn on as it should?

[flipfire]

yeah.. thermofan switch is separate to the thermostat. Its a sensor that sticks into the housing and senses water temps.

if it doesnt work and the car is severly overheating, use a paperclip to keep the fan always running

[fromdeeeast]

Yer thats what I thought after taking the thermostat off yesterday.

I guess I'll try it tomorrow and see how that goes, hopefully works

fingers crossed!

are you sure its not your gauge?
