overheating

i replaced the thermostat and yes it has the air bleeder and replaced the water pump. checked the coolant and everything. i got a remanufactured ka24e motor and im running 5-30w oil. it still overheating and i dont know wat else it could be. i also checked the radiator and water flows good. does anyone think its the oil or maybe the electric fan? i wired it to the eng ctrl fuse and it has a fuse link. it still overheats and i dont know what else it could be.

hrm.. thermo and water pump works? that's weird... well you are using 5w oil (which is pretty low) but that shouldn't be the problem causing overheating. Maybe you can remove the thermo... then the cooling will be on 24/7 no matter what the engine temperature is... hence, it might even keep the heating to a minimal. This isn't a definite or longterm solution so find the problem by testing things here and there. I just know my friends with aftermarket turbo setups remove that so it runs all the time instead of engaging after it hits so-many degrees and what not.

sry not much of help... but yea... 2 yen.

electric fan?? u don't have the clutch fan?

electric fan?? u don't have the clutch fan?

i got a flex a lite electric fan. go to their website and get the control box. my dad works there so any questions you got email me at [email protected]

i have an electric fan no fan clutch. about removing the thermostat... CAN U EVEN DO THAT? will the car be fine?

its the your radiator cap!!!!!!!
its leaking pressure
best cap for it is the oem from dealer
trust me, its only about 20somethingbucks...
thats if u still got your stock radiator,oh take off any bugs or trash stuck
on it,it helps..(radiator) check your hoses for leaks.

i just changed my whole cooling system
and it still overheating and finally i changed the cap.
it thought it was good cuz it looked like new
but it was leaking.@#$%^##!!!!sh!!t

lol that sux bro. But atleast you know you have an updated cooling system.

There is a possiblity that its the cap, however check the guage to make sure everything is copesetic as well. Another slight possibilty is( not trying to patronize you in any way) make sure you have the correct type of coolant. Should be green, if its orange/pink your usin the wrong stuff.

wouldnt that suck if you put all that work into it and its just a friggin radiator cap...lol

use a radiator testor to make sure it holds pressure. Let the testor sit, if pressure doesnt drop for like 10min, then your probably ok. And change the cap and see if that helps.

i have the nismo one !

change radiator and get a good fan. radiator is most likely your prob.

i seriousli doubt its the radiator. i took it out and put a garden hose to see if water flows and a lot of water comes out so yeah. but i think its the radiator cap cuz i havent changed it for like 3 yrs

haha... imagine that. sometimes... keeping things simple is good.




a freakin' rad cap.

I doubted my radiater too, then i found a hose leak so i replaced the radiator for nothing.lol

ok i changed the radiator cap and its still doin it. im not sure but im thinkin its the thermostat i just got it from some foreign parts place. i was thinkin about gettin an oem one but im not sure.

i replaced the radiator cap and its not it. its still overheating. im think its the thermostat but im not sure cuz i just got it from some foreign parts place. i was thinkin about getting the oem one but im sure. other than that i realli dont kno what it could really be.

i replaced the radiator cap. its not it. its still overheating. im sure wat it is, but i thinkin its the thermostat. i just got it from some foreign parts place. should i get the OEM one or not? its 170 degrees. thats the stock one right?

so you bought a new thermo? and you think its bad? Is there any leaks anywhere? How much did you pay for this thermostat? Maybe you should go down to baxter or a respectable parts store and buy the right thermo.

Man i am having the exact same problem but ive done everything and nothin gets better, it seems to be getting worse, ok i have changed out the waterpump, fan clutch, 170 degree thermostat, gone thru two radiator caps bought a new 16lb and now ive got a 13lb, flushed the radiator, and took it today to have it rodded out and just put it all back together and its still over heating, it all started about a month ago when i put the water pump on, i have heard that u have to pay attention to buying water pumps from places other than the dealers because the propellers on the auto parts store pump arent always the exact length of the oem is this true? i am at my wits end with this car i am seriously contemplating selling it ,nothing but trouble and its busting my bank ,what is there left to do?

are you guys filling the radiator with coolant right? Do you know how you properly do it? You dont just poor it in...

Flush It Water First,let The Therm Open
Flush It.let It Cool (if Your Rad.works Cool H20 Will Come Out First Then Hot From The Block.)

Fill With 5050coolant(best Choice)
Fill Resvior Between Min & Max
Let Therm Open
This Is The Tricky Part
The Reservior Coolant Is Suppose To Be Suckd In By
Vaccum (but That Wont Really Do The Trick.)
Check And See If The Coolant Is Being Drawn Into The Radiator
If That Doesnt Work Then Then Ill See Your Post Here I Got A Bunch Of Info On Overheating.goodluck.

If The Gauge Doesnt Stay In Normal Operating Temp
For A Lil While Then Its Your Therm.or U Just Test
It Compare To The Old One (in Hot Watta)
Yes Experience = Headache/$$$

yes i am filling it right. i have also opened the bleeder valve for around 30 mins and nothin but either bubble or a foam like stuff comes out never actual stream of coolant/water. any one know about the water pump question i had? if the propellers are always the same from autoparts store to oem? and since i have put the radiator on last night when i drive the temp gauge goes down when im on the gas but as soon as i push in the clutch to shift it goes up the when i let out for next gear it shoots back down. so whats the deal? DAS14sniper i believe i need all ur overheating info. haha

if you are using a thermostat from autozone it will ALWAYS overheat. they don't have air bleeder holes in them.

go to your local nissan dealer, buy a radiator cap and thermostat. oem stuff is always best.

if its still overheating check if your fan is working. mechanical fan? ok, if so that's not the problem.

do you have a front mount intercooler? if so its definitely your radiator. the fmic blocks air coming to the radiator, so you need more radiator thickness and it almost has to be aluminum. koyo sells an awesome one for around 300/shipped.

if you are still overheating its either your water pump or there is shit in your engine's head, or a bad head gasket.


make sure you are bleeding it correctly.



1. Fill the overflow tank to the full line.
2. Make sure heater is fully on the hot side.
3. Remove engine bleeder screw and radiator cap
4. Fill very slowly until coolant comes through bleeder.
5. Close bleeder.
6. Continue filling until radiator is full.
7. Squeeze all hoses to release more air. Keep radiator topped off.
8. When full, install radiator cap and run engine.
9. Fill overflow and radiator as necessary. Keep heater on hot.
10. Hope to god it works because you really don't want to repeat the process again.

Check Your Electric Fan If Turns On.
If It Cools Down When U Drive It, Coolant Is Flowing.
Hows Your Clutch,did U Changed It Recently
I Read That If Your Clucth Is Worn Or Not
Properly Alligned Its Causes Heat From Friction Heat Transfers Make Your Block Hot.im Going To Look Up The Source And Give The Link.(i Never Heard Of It But It Could Be Possible )

I dont know what DAS14 was trying to say, but this is the proper way to fill with coolent. Leave the engine running after you do this for about 5-10min, then come back and open the radiator and see if its still full...

yea i was thinking head gasket....thats what caused my car to overheat all the time. Got a new one and it runs at correct temps. Yea, it cools down when your moving then you slow down or stop and temp gauge goes up up up. Then you get going again and down it goes. I feel ya on that, i had to drive in the summer with my heater on....talk about schwetty balls.

i didn't even follow those myself lol. just undo bleeder screw, fill until it topples out, close it off, and fill the rest up. put radiator cap on and go drive. past that the cooling system will basically bleed itself.

ok guys i appreciate all of ure help...it wasnt the water pump, thermostat, electric fan, radiator cap... it wasnt none of that.....pist me off tooo......my cluster was bad.........i changed the cluster and everythin was normal......can believe it was the fuckin cluster......all that work too....

AHAHAHA, sorry to laugh. But that is the bitch of doing things yourself. I hate when shit like that happens, oh well, as long as you got it running now!

yea pretty sure mine was the water pump i took the one i bought from oriellys off and bought one from the dealer ship yesterday($82) and the blades are no where near the same, the angle the blades sit at is no where near the same and the width of the blades are different so thats what my problem was thanx for the help though i appreciate it
