Changed Turbo And Now Overheating!

[toan]

hey guys

i just changed the turbo on my r32 gts4, i put in a R33 turbo that was rebuilt and hiflow'd! also using a justjap slipt dump pipe(screamer)

car was running perfectly fine! the turbo lines were just all cut off and a hose fitted and tightend.

coolent is flused and new. car runs fine as it is without steping on it but then when i step on it within like a minute or so the temp gauge starts going up high!

When the car is turned off i can hear the water boiling.

Nothing is leaking!

hope someone can help so i can resolve this problem!

thanks

hmm strange...

the turbo lines were just all cut off and a hose fitted and tightend.

explain this?

you mean to say your running a water cooled turbo, without the water lines attached?

[geraus]

Have you checked your coolant levels? checked if there toped up and did u bleed it correctly? theres a little bleed bolt on top of the throttle body

[Guilt-Toy]

you have not bleed the cooling system correctly. you should fix this ASAP before you damage your engine.

If you are unsure how to do this, take your car to a mechanic who knows how to bleed skylines and get it done properly.

You might have an air lock in your cooling system for when you flushed it. If so, try starting your car with the rad cap open. keep it open even afther the thermostat opens. this way the bubbles will eventually go away. Hope it help!

BLEED THE SYSTEM

[toan]

thanks guys i didnt know there was a bleed nut on there!

i opened the radiator and left the car running and filled it up.

how do i bleed it? sry to be pain!

[Sheriff Wan]

There should be a small (8mm?) bolt on the intake plenum, right near where the PCV valve is. Unscrew this a little bit and run the car for a short period - you should see tiny little bubbles.

That should do the trick

Cheers

[toan]

ah ok! so do i take that bolt of of? or half way or something?

[payback21]

Take it all the way out. It pays to turn heater on to get the air out of the heater system aswell. Water will trickle out when the air is out. It does take a little while for the water to come out okies.

[SECURITY]

take it somewhere to bleed it if you arent sure, you could easily have your temps over 100 degrees without even knowing it.

if you INSIST to do it yourself the steps are:

- start the car with the radiator cap off, keep topping it up till its filled.

- turn on the heater to the HOTTEST setting and run it at its maximum speed.

- loosen the bleeder till its around 1 thread till its off and keep it there till its completely bled.

- keep going till no bubbles come out of the bleeder.

you can use some kind of funnel type thing (see below) to help it along.

i dont have a bleeder on mine, i do the old 'put on a sealed bottle to raise the highest point of the cooling system' trick. works well, car bleeds pretty quick. you have to block off the overflow hose for it to work properly though.

ok guys

i have done what sercurity said! i went for a drive everything is ok untill i step on it! same things is happening!

a friend of a friend of mine said his car was doing the same thing untill he got it tuned, is that correct?

[WYTSKY]

I changed the coolant not long ago in mine... I did all the things security has mentioned.... thought all the bubbles were out, took it for a drive and on the pfc it was telling me straight away that the temps were going up... went straight back home (only got down the street) i let it bleed for 15 mins which i thought was enough.... ended up taking like 30 mins with the heater going full.... so how long did u bleed urs for?

[SECURITY]

you replied 30mins after i posted - i highly doubt you did it right mate.

i wait there, squeeze both of the radiator hoses continuously as im topping up my funnel thing - it just helps get ALL of the air bubbles out. i suggest taking it to someone who knows what theyre doing.

[toan]

hey sercurity

i got the same steps as u from another site and did it earlier.

i drove it around again last nite samething

[West]

Have you taken your radiator out to a radiator place for service yet? Check your radiator cap to see if the seal lip (rubber lip) is still in a good condition?

[SECURITY]

yeah good point.. are you losing water?

just take it to a mechanic. what state are you from?

[West]

From memory, even your clutch fan might be slipping as well....

[payback21]

Not that i want to say it, but possible cracked head. Perform CO2 test on radiator to check this.

[LANDSCRIBBLE]

Mate dont risk f**king your engine up, dont touch it unless you know exactly what ya doing, take it, wait, and pay a proffessional mechanic to do it the right way, then you can get that piece of mind and sleep like a baby.

dont mean to sound like a dickhead, but i dont want your car to blow up
