DaGr81 Posted January 3, 2009 Share Posted January 3, 2009 Just let the gauge get to the middle since you don't have aftermarket one or a PFC, after it reaches the middle let it run for another few mind the put the cap on and turn off Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4346099 Share on other sites More sharing options...
Jay_R33 Posted January 4, 2009 Author Share Posted January 4, 2009 ok this morning, i flushed out the coolant, put some coolant flush through it to try and unclog any blockages, then filled it up bled it by having the cap off and heater in full ball and now we wait and see if it is all good..will keep posted Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4346628 Share on other sites More sharing options...
Bond Posted January 4, 2009 Share Posted January 4, 2009 Overheating is also caused by a worn clutch fan. These can be refilled with silicon oil for around $10 or bought new for $300....i prefered the $10 option.

These can be refilled with silicon oil for around $10 or bought new for $300....i prefered the $10 option. Brand new price is >$300 And $10 for new oil? I had no idea you could just replace that...clutch fan is easy to test anyway...once the engine is warmed up it shouldn't free spin anymore, it should be locking a little at idle...

Jay_R33 Posted January 4, 2009 Author Share Posted January 4, 2009 the car isint overheating as is, just because the top radiotor hose pops off and spills all the coolant out then it overheats Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4346952 Share on other sites More sharing options...
89CAL Posted January 4, 2009 Share Posted January 4, 2009 howd u go? as above, about halfway on the gauge is around 80 degrees or so. In regards to the horn on my old VL I had a similar problem where it would go off randomly, one time i was driving down my driveway just about to pull onto the road and it just went off and wouldnt stop. This happened just as a cop car was driving past lol lucky they didnt seem to care. Anyways, it was an aftermarket steering wheel and if i tightened it up to tight that would cause it to go off when i indicated or turned or something like that, it was also blowing a fuse which would make the relay for the horn click on and have it go off. It was due to a bad earth or something so just check the wiring, if youve got a standard steering wheel that uve never touched then it probably wont be that but just an idea for you Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4347235 Share on other sites More sharing options...

Nah the horn is stock standard, prob is it has an airbag so i cant just remove it, but i kno what u saying mine goes off sometimes at the slightest turn roundabouts mainly and sometimes it goes mental and wont stop and i just have to press the horn button on the wheel and it stops really fkn weird, it actually one time went off when the car was parked in the garage and i slammed the bonnet shut it was mental...no one seems to know Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4347534 Share on other sites More sharing options...
Jay_R33 Posted January 9, 2009 Author Share Posted January 9, 2009 ok i went to natrad in seaford today highly recommended by the way and he took the hose off and found the problem right away, the part of the radiator that the top hose connects to has broken off the ridge part that stops it from sliding off when the hose clamp is on....it was broken in the hose and we just fished it out and pretty much now need a new top filler bottle, was quoted $260 hope thats a good price anyway for the time being he put this plastic ridge on it dont know how he did it...like this blue silicon stuff, very dodgy as he said but will get me by til i get it fixed so we shall see how it goes now thanks for all the help people always appreciated Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4357393 Share on other sites More sharing options...

Jay_R33 Posted January 10, 2009 Author Share Posted January 10, 2009 well for a update today whilst driving the car overheated again pulled off opened bonnet and what do u know the hose has not blown off this time so I was stumped, however the steam was coming from the other end of the top radiator hose the one that connects to the engine, I felt the clamp and it felt lose so I gt my screwdriver out and I could move the hose clamp around so I tightened it, put water back in and it was fine was at normal temp, the racv dude reckons all it water hoses under the engine need to be replaced as they are still original does that sound right? I was on nepean hwy just past edithvale station is anyone saw me LOL Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4359302 Share on other sites More sharing options...
No Crust Racing Posted January 10, 2009 Share Posted January 10, 2009 Old hoses become brittle and do not flex enough to seal. So new hoses might be the go. Natrad should have told you this though? Usually they jump at the chance to sell you more shit. Replace the hose and the clamp, cheap as chips, be sure to clean the connecting pipe on the engine side. Also, while you have that pipe off you can check the thermostat for jamming. Good luck and let us know how you go.

gotRICE? Posted January 10, 2009 Share Posted January 10, 2009 Look on Ebay. There should be plenty of cheap aftermarket silicon hoses on there! Thermostat is located at the end of the bottom Radiator hose. 3 bolts holding the housing in. Piece of cake to change Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4360296 Share on other sites More sharing options...
Jay_R33 Posted January 10, 2009 Author Share Posted January 10, 2009 arghh the bottom radiator hose is such a bitch to undo lol i did it to drain the radiator as i couldnt locate the valve to open it and then when i had to put it back on pwahhh the chassis got in the way big time...will check ebay now thanks dude Link to comment https://www.sau.com.au/forums/topic/250368-skyline-overheating/page/2/#findComment-4360328 Share on other sites More sharing options...
gotRICE? Posted January 10, 2009 Share Posted January 10, 2009 Nooo its at the block end of the bottom hose hehe. You only need to undo it from the engine side, not the radiator side Also theres some cheaper silicon hoses on www.trademe.co.nz too.

89CAL Posted January 11, 2009 Share Posted January 11, 2009 Id say with the horn thing if ur pressing the horn button on your steering wheel and thats making it go away then its probably a problem up around the steering wheel area as i said before. Dunno how u go about pulling the steering wheel off to check it seen as it has an air bag maybe pull the colum surround off and try to look up and see if u can see any thing loose or broken Thats my guess anyway....
