SkylineV35 Posted July 10, 2013 Share Posted July 10, 2013 (edited) Usually my temp reading sits a little below the halfway line on the temp reading, but the other day i was parked with the engine idling waiting for a friend, was getting hot so rolled up the windows and turned on the A/C and maxed it out to coldest possible setting, 15mins later i noticed the temperature had climbed close to the H on the temp reading and then i quickly looked at the outside temp reading and it read 32degrees!! So in a panic i switched off the car. When my friend finally came down, i got in the car and decided to turn off aircon, turn on the heating to max and gave it a quick blast to force some air into the engine bay, a few minutes later the temperature finally went down to half way but not as low as it usually sits. That was 3days ago and the temperature has been fine ever since but is there anything i should actually check to prevent this from happening? Or does idling with aircon on have this effect? Any ideas? Eg thermostat or fan etc... Thanks Saskhi Edited July 10, 2013 by SkylineV35 Quote Link to comment Share on other sites More sharing options...
bamdc2 Posted July 10, 2013 Share Posted July 10, 2013 Havent heard of that before. You checked water/coolant fluid levels? Quote Link to comment Share on other sites More sharing options...
cs2000 Posted July 10, 2013 Share Posted July 10, 2013 Sounds like the fans are failing. Yes, using cold air rather than hot will warm the engine up as you aren't taking the heat away from the block, however the fans should kick in at about half temp reading and keep everything cool.

JetSet Posted July 10, 2013 Share Posted July 10, 2013 I saw a few Zed's in Las Vegas when the ambient temperatures was over 45 so I would imagine its a fan problem. Pete Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted July 10, 2013 Author Share Posted July 10, 2013 Water and coolant levels seem to be fine. Hmmm... il try get her up to temperature later and listen for the fans. Do you think one of those low temperature thermostats would help? Quote Link to comment Share on other sites More sharing options...
M13KYF Posted July 10, 2013 Share Posted July 10, 2013 I would check the fans first, Some members have had issues Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted July 10, 2013 Share Posted July 10, 2013 It will be your fan motors not kicking in Saskhi. New fan motors are in stock as well as the Mishimoto complete fan shroud unit. Alex. Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted July 13, 2013 Author Share Posted July 13, 2013 (edited) I had a look at your Mishimoto complete fan shroud units and they look amazing! But i think my fans are working, im trying to recreate what i did the other day to see if the fans kick in and cutout at somepoint... I will try again today as it is supposed to be really hot today too! I think it might actually have something to do with the aircon being on on idle but normally without aircon on the temp will sit below the middle of temp gauge with no fluctuations in readings or anything.

SkylineV35 Posted July 14, 2013 Author Share Posted July 14, 2013 Yes one of the fans dont spin... so iguess its good enough excuse for mishimoto fan shroud alex! let me save a few pennies first.. Quote Link to comment Share on other sites More sharing options...

SkylineV35 Posted July 24, 2013 Author Share Posted July 24, 2013 Just recieved this today thanks Alex! Now need to get me a soldering kit, any suggestions? would maplin or B&Q have one? Looks an impressive piece of kit though must say! Quote Link to comment Share on other sites More sharing options...
hensh65 Posted July 24, 2013 Share Posted July 24, 2013 Had the same issue mate, nice bit of kit you have there ! Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted July 24, 2013 Author Share Posted July 24, 2013 Had the same issue mate, nice bit of kit you have there ! Yup hope i dont waste it though never soldered before could imagine its something like welding... fingers crossed! Quote Link to comment Share on other sites More sharing options...

I have soldered since uni but it is not hard, welding is much harder so you will be fine. Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted July 24, 2013 Author Share Posted July 24, 2013 getting the fan out was easy apart from burning the crap out of my hand when disconeecting the hose to the radiator lol Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted July 24, 2013 Author Share Posted July 24, 2013 (edited) Before.. After... ..dare i say it...the wiring almost looks oem! lol lol Edited July 24, 2013 by SkylineV35 Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted July 24, 2013 Author Share Posted July 24, 2013 (edited) Finally installed only problem with fitment was the too bits at the top that needed a lil bending with sum grips and pliers but nothing too stressful! topt up coolant and waited to hear the fans sing and sing they did sounded like a jet taking off PLEASE ANSWER WITH YOUR THEORY ON THIS ONE ANY ANSWERS WELCOME! Quick question is it better for fans to suck cold air into the engine bay... or blow the hot air from inside out of the engine bay?? what does the stock one do? Thanks Edited July 24, 2013 by SkylineV35 Quote Link to comment Share on other sites More sharing options...
Ricey Posted July 24, 2013 Share Posted July 24, 2013 I'd say blow hot air out as presumably the cooling system and air intake take care of the 'cool' bit so the priority of the fan is to extract the hot bit.

GT Driver Posted July 24, 2013 Share Posted July 24, 2013 Interesting. Was the soldering difficult? What guide did you use- looking at the pictures there are 4 wires in the OEM connections- 2 of these wires on each connector are being soldered to one of the two wires on the new fan shroud?

Opinion based on zero experience, knowledge or nouse But when driving at speed the hot air being pushed out will be cancelled out by air resistance blowing air in will it not? i can understand at idle hot air out is good idea as no air being rammed in.. the fans are two way but im thinking if nissan made it suck cold air in there would be a reason be behind it...

I just used a connections diagram provided by alex, i tested it out and both fans come on instead of the previous one, and aircon sets it off too, whereas the old setup the second fan would kick in when aircon comes on or temp are reallly really hot. Soldering wasnt that bad was a pain in the ass to heat up properly, mental note if ever soldering again dont buy cheapy one lol Quote Link to comment Share on other sites More sharing options...
