KA24DE overheating ,radiator fan?

[topairhead]

please help?the temp is good untill i come to a stop and the temp goes up.i have put anti-freeze and it last up to 1 day in normal temp the next day it overheats only when i come to a stop.

Could this be the fan???thanks.

So it's a stock Ka24de right? So did you check your radiator? Like hoses? Radiator itself (upper tank bottom tank, any cracks?) How's the coolent? It should be 50%water50%anti-freeze. Not 100% anti-freeze. Is the fan working? The fan behind the radiator should runs all the time. Also you know sometimes after the engine overheated. The thermometer wouldnt work normal. You might as well try to get a new thermometer it cost under 10. Just check all those stuff first and see what's up. Goodluck!

Are talking about the AC fan not spinning?

Are you loosing coolant? Have you checked the thermostat?

[topairhead]

thats the ac fan?? well the fan right infront of the radiator dosent spin.and no i havent checked the thermostat.

could u give detailed directions on how to do this please im not good in cars but i learn by researching .thanks

If you have to add coolant everyday to keep it from overheating, then I would look for obvious leaks first before trying to replace random parts.

Have you pegged the needle to the hot side when it overheated? May need to check the head gasket or head itself for warping.

no leaks. the only thing that seems weird is when is low on coolant the temp goes up but as soon i accelerate the temp goes down....??and how do u pagged the needle on the hot side ?

[irocknrol2]

and how do u pagged the needle on the hot side ?

What I believe he was asking you is ..have you pegged the needle on the hot side, in other words have you run the engine hot.

You probably have some air in the system. If you are adding coolant, then you very definitely have a leak somewhere, it may not be that noticeable at first. But coolant doesnt evaporate very fast.

The big white bladed fan on the front of the engine should be running when the engine is running. The smaller black electrical fan mounted to the radiator is a fan for the a/c and will not be running all the time.

Hope that makes sense to you.

[Zion8561]

It makes sense that as you start going faster you will get more airflow, waterpump spins faster...

Seems like you can either find out why your coolant is disappearing so quickly and fix that, or just keep adding more everyday you drive it.

ok i just filled my radiator with coolant and i found that it is leaking...it seems to be leaking under were the water pump is at in that section.any one give me any tuturiols on this type of problem thanks.

Your water pump is bad. It is leaking from the small weep hole on the underside. Replace the water pump.

[topairhead]

well im not exactly sure were is leaking from but it seems its leaking from somewere and its leaking slowly really slow lil drops.... well ima see wat i can do thanks.

The overheating when the car is at a standstill may be due to a bad clutch fan on the mechanical fan; during idling, the fan should be fully engaged and spinning and at high speeds, it becomes free-wheeling.

I just went through this same issue about 8 months ago. I took it to the shop to have the thermostat replaced, due to lack of time. That seemed to work for a couple of weeks then the overheating returned. The car was fine at running speed, but when I came to a stop it was heating up. I spent a little time looking for leaks and found the water pump was leeking. I then changed out the water pump and the thermostat (again). While you are doing all that get a new belt also. The car has been running great since. Hope that helps.

[topairhead]

yeah thanks i had my water pump changed a while back about 4 months ago and yeah i think i am goign to put a new belt since i hear a weird noise coming from there. but then it goes away. well right now my water pump is not leaking...and yes i look at the engine fan and it spins kinda slowly like before i can high air but now is low ima gett it checked by a mechanic see wat comes up. thanks againg. --
