StealthX Posted November 24, 2009 Share Posted November 24, 2009 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?

Guilt-Toy Posted November 24, 2009 Share Posted November 24, 2009 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.

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! Cheers!

Sheriff Wan Posted November 25, 2009 Share Posted November 25, 2009 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 Link to comment https://www.sau.com.au/forums/topic/297629-changed-turbo-and-now-overheating/#findComment-4954631 Share on other sites More sharing options...
toan Posted November 25, 2009 Author Share Posted November 25, 2009 ah ok! so do i take that bolt of of? or half way or something? Link to comment https://www.sau.com.au/forums/topic/297629-changed-turbo-and-now-overheating/#findComment-4955105 Share on other sites More sharing options...
payback21 Posted November 25, 2009 Share Posted November 25, 2009 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 Posted November 25, 2009 Share Posted November 25, 2009 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.

WYTSKY Posted November 25, 2009 Share Posted November 25, 2009 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 Posted November 25, 2009 Share Posted November 25, 2009 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.

West Posted November 26, 2009 Share Posted November 26, 2009 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?
