ka overheating

[s13boy89]

i have a question on a ka i installed alright here goes. i recently purchased an s14 ka i put my s13 intake on there since all the emissions and most of the coolant lines are gone. when i put it back on i didn't have a gasket so i used silicone. i was wondering if it should be fine because the car likes to over heat on spirited driving, but if i let it cool down it will be fine again so i want to know if it is my hg or my shitty silicone job. also yes i have bled it several times, i also took off the thermostat to see if that was the problem and it wasn't. also i have no thermo and it still does it and i dont have heater anymore so i cant bleed it

[tre4s13]

Bleeding it several times just doesn't seem to do the trick on KA motors. When it warms up, cut it off....open bleeder purge on manifold, refill...cool off, repeat...till you see NO bubbles come out that little bastard.

[s13boy89]

yeah i have a radiaotr cap that lets all the bubbles out when i flick the switch but water comes out as well and when i squeeze the hose they are rock hard are they supposed to be like that

[tre4s13]

I do also, but don't use that it'll just push the air into your over flow tube...lol just do it how i told ya, TRUST me it works. top off, warm up, cut off, bleed, cool down. REPEAT!

[tre4s13]

oh yea, and don't forget to let your car cool down for FIFTEEN minutes. i think this is important...

[tre4s13]

This is what I used after I did my ka-e to de swap.

and it works.

[s13boy89]

bled it all day and still gets hot

[stealthsr20]

have you pressure tested the motor?

[s13boy89]

no i havent

what does your oil look like? chocolate milk?

does it overheat idling? or while driving?

kinda confused where you used the silicone too...

edit: check out FSM for proper coolant bleeding procedure

his overheats while driving im pretty sure cause at idle it did not overheat

how long did you guys let it idle for?

[s13boy89]

i have no heater, it starts to overheat while driving and no the oil has no coolant in it

Did you switch over coolant sensors? I had this problem when i put my 91 ka in my 95 240. I thought is was overheating but i found out that the single pin coolant sensors have different resistance values and it will make the temp gauge read hot on and s14 cluster.

[essforteen]

when was the last time you changed your water pump?

[s13boy89]

i just changed it when i put in my motor and the temp sensor its the same one from my other motor

[essforteen]

is it gurgling into the overflow tank

[s13boy89]

yeah it gurgling

I had a similar problem like this. Still havent fixed it. Interested to see whats going on with it.

[s13boy89]

so i found out my water pump was leaking and that my lower radiator hose was gushing water so i fixed that and also put a new thermo on and so far it hasnt over heated

[tramp_drift240]

how. in the hell. did you not notice that your lower hose was "gushing" water.

doesnt "gushing" normally seem like....a water balloon that got busted. or a raging river.

[s13boy89]

nah i fixed it then i went to a meet the i noticed i had a puddle

[tramp_drift240]

that doesnt really explain why your hoses were as pressurized as you said.

when my hoses were like that, my HG had caused a tunned from the combustion chamber to the coolant jackets. ergo, super pumped cooling system.

[nismo racer]

Mine gurgles into overflow tank aswell but nver ever over heats.

[shytdoode]

can always be a bad radiator or water pump

[s13boy89]

ehh it doesnt overheat anymore so ill leave it
