redheadordead Posted July 13, 2015 Share Posted July 13, 2015 Hi all, I have the Skyline 350GT, same engine as the Z with an issue that nobody appears to know how to resolve The water temp shoots up if i maintain over 2500 revs for more than 15 min, ie motorway driving, if i then put the cabin heat on the temp will come back to normal no matter how quick i go, turn the heat off and it rises again So far car has had new thermostat, water pump checked and all fine, system pressure checked, all ok, sniffer test ok, burped, ok, HG checked and all ok, anything i missed? All help much appreciated - the guys on the skyline forum are helping as well Quote Link to comment Share on other sites More sharing options...

Ebized Posted July 13, 2015 Share Posted July 13, 2015 Given what you have done and if no water loss - partially blocked rad/collasped pipe/air in the system? If you have found the fans are coming on OK to deal with the temperatures when stationary/slow moving traffic it kinda says the water ain't going round as it should. 1 Quote Link to comment Share on other sites More sharing options...
Payco Posted July 13, 2015 Share Posted July 13, 2015 Have you released the little plastic screw valve near the bulkhead to check for any /clear air locks that might be there. I had a similar issue a few weeks back. Give all the pipes a good squeeze whilst the car is running. Mind you don't lose your fingers on the belts though.

redheadordead Posted July 13, 2015 Author Share Posted July 13, 2015 Cheers guys, yes the fans are all checked and kicking in nicely, i have suggested a blocked radiator and this is my next route i guess, "little plastic screw valve near the bulkhead" can yoube a little more specific as to where this is? Sorry not technical...Cheers for the advice so far Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 13, 2015 Share Posted July 13, 2015 I thought I suggested a partially blocked rad some time ago, has this not been checked then? Quote Link to comment Share on other sites More sharing options...
