Yesterday I was driving home with the A/C on and noticed the temp was slightly up. Normally the gauge needle is in the middle ( flat ) or just below but yesterday it was about 3mm above the middle. I'm not getting too concerned just yet but was just wondering how other RB25DE NEO owners run temp wise on a hot day ?? Especially those of you up in QLD or WA who cop big temps.

Feedback please. :thumbsup:

I think it was around the low 30's mark.

Also, noticed that lately the thermo fan has been on even at normalish operating temps :thumbsup:

I thought it was only supposed to come on if the A/C was on or if the engine temp got too hot, but not at normalish operating temps.

By engine temp and the gauge you mean water temp, have you checked your coolant recently to see if it's full, look at the overflow as well, also if you haven't flushed your radiator recently give it a go, mines always in the middle and never see's anymore than 80 degrees according to aftermarket gauge I found out the hard way once it was rising but when your cruising it goes back to normal, then when you leave it to idle it rises, I checked 2 things .. Leak in radiator and water pump turned out to be hole in radiator about 70 bucks to repair

But I've got aftermarket radiator so yeah temps can drop to 70 while cruising

Can't find any leaks, heaps of A grade coolant etc. Today was around the same temp but the engine temp didn't go up so........ ;)

Here's where the temp normally is and the red line is where it went up to.

Maybe a sticking thermostat. Will have to monitor I guess.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
