Skyline Overheating

[Jay_R33]

How do u know when it hits 77 degrees? And where is this valve located?

[Jay_R33]

whilst I'm under the car how do I disconnect the horn, mine goes off randomly at times when I'm driving, Want to disconnect it til I figure out what is wrong any ideas? P.a thanks for all the advice people

[DaGr81]

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

[Jay_R33]

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

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.

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...

the car isint overheating as is, just because the top radiotor hose pops off and spills all the coolant out then it overheats

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

yeah all went well thanks dude, prob go to the radiator specialists tomorrow to try and get a pressure test done to see exactly what was happening.

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

[Jay_R33]

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

[No Crust Racing]

Sounds like I was on the right track then, good to know

[Jay_R33]

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

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.

i rang the radiator guy and he said he couldnt beleive he forgot to check the other end of the hose...he reckons they dont build up pressure if its actually lose...how on earth am i gona replace all the hoses under the engine lol that will cost a fortune as i would prob have to order from nissan who are not cheap.....i will replace the engine hose and clamp at the very least

silly question where is the thermostat exactly located so i can check it?

[gotRICE?]

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

[Jay_R33]

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

[gotRICE?]

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.

[Jay_R33]

yeah will check it out lol im such a noob sorry bro

p.s just saw u were from new zealand lol Me Too!! well not living there but yeah except from good ol Auckland

[gotRICE?]

Good Ol Auckland? HA!

No worries. GL with it.

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....
