hey guys my car is overvheating I ffigured out that my fans haven't been kicking in do u thinknthat that's the problem would they make that big of a difference or could it be mybwater pump? The car will get hot real fast.

 

start with the fans not turning on....I mean they're there to prevent overheating and since they're not on,well,BINGO!Also,do a search for fan problems,fan mods,etc.Youll find tons of information on this.Good Luck

 

If the car isn't moving forward, or is moving forward slowly, then the fans absolutely matter. On the highway, not so much.

 

ya I'm going to work withthe fans I'll get back u Tha if it works

 

I Fixed the fan problem but its still doing it i just drained all my rad fluid do u think it could be air bubbles?

 

Certainly could be - that would fit the symptom of quickly overheating. Burp the system - one of the common ways is to disconnect the coolant hose that goes into the throttle body and fill coolant until it starts to come out there. That usually works fairly well.

 

Can you be more specific? What temperatures are you seeing? How long does it take to get there? Have you tried touching the radiator hoses to see if they are both warm?

 

same issues with me trying to figure it out. i have a brand new radiator,thermostat,and water pump and still overheating

 

Blown coolant seals come to mind...

 

it takes a bit to get hot my system seems completely full will the air bubbles clear themselves out as I drive it on and off and I don't think I have blown seals that is not on my mind

 

bump answer?

 

Bump, answer some questions:

 

my normal running temp is 87 c it warms up faster than normal and it takes a little bit to actually go past the normal temperature i usually pull over and allow it to cool down the radiator hoses are warm as usual do u think it could be a busted thermostat or does the system still have air bubbles in it. im not sure if the system clears itself out of the bubbles or something i need to do myself? i would say from a dead cold motor it takes 15 min. if im driving to get past normal temps.

 

What is the highest temperature you are seeing?

 

well i never wanted it to get too high but 94 c was the highest so far

 

94 degress is far from anything to be worried about.

 

94C is nothing. The fans don't even kick on in stock form until 105C. If you have the stock thermostat, it's not even fully open until around 94C.

 

i know but before it got as high as 100 and rising it seems to be getting better and better as i drive it thats why i think its air bubbles in my system becasue i just replaced the rad fluid no one has beeen answering my question on whether or not the car clears itself of the bubbles on its own and how fast it does if it did

 

It's a closed system so there is only so much it can do. If you have a LOT of air in the system, the car will not clear it all on it's own.

This is how I recommend filling and burping the system:

thanks i appreciate the help ill try it out later tonight and get back to you hopefully thats the problem and that will make you my savour

 

When you say that it got up to 100 degrees C, were you climbing a hill? The stock cooling system on these cars is not the greatest (as I'm sure you know), and even after my fresh rebuild my temps would climb consistently every time I went up a hill at partial throttle.

The truth of the matter (IMHO) is that the stock radiator is undersized for the 13B-REW. I saw as high as 107 degrees C on a hot day while climbing Belden hill going out to my friend's house.

Do yourself a favor...Invest in a Fluidyne (or Koyo) radiator, and watch those temps drop drastically. Probably one of the best investments I've made for the car. (I have the Fluidyne) Now, when it warms up it'll hover between 82 and 85 degrees C, and the hottest it EVER gets driving (going up hill, flat road, down hill, etc) is 87 degrees C, and that's rare. It'll usually stay around 84/85 degrees.

 

I have after market everything includeing a koyo that's why I'm worried my car never went over 87 c even when I drove it hard it has 375 horse power and I live in Florida so there are no hills I know the Temps don't seem high to u guys but my car has ran at this temp for a while and now that it's screwing up it throws up a red flag for me I believe it's just air in my system hopefully it works if not then maybe I have a blown seal
