Saturn Posted January 10, 2018 Share Posted January 10, 2018 normally a bad alternator trips the battery light and the brake lght, not the AT cooler. Did you disconnect the cooler lines when you did the alternator? Link to comment Share on other sites More sharing options...

XPLORx4 Posted January 10, 2018 Share Posted January 10, 2018 As far as I can recall, there is no dummy light for a leaking ATF cooler. The primary ATF cooler is incorporated into the bottom tank of the radiator, and certain models had an external cooler mounted in front of the AC condenser. There is an AT TEMP light, which also glows with the batt and brake lights when the alternator output is too low. What is the voltage at the battery terminals when the engine is running? I suspect the alternator, its internal voltage regulator, or the connections to the alternator. Link to comment Share on other sites More sharing options...
XPLORx4 Posted January 10, 2018 Share Posted January 10, 2018 If the alternator is new, also check the white wire pair between the battery positive terminal and the fuse/relay box. Those wires can sometimes harden and corrode and create electrical problems. Link to comment Share on other sites More sharing options...
Saturn Posted January 10, 2018 Share Posted January 10, 2018 Xplorx4 is correct, AT fluid runs through the bottom of the radiator, there is no dedicated AT cooler unless it has an aftermarket one, so if it's leaking its either the lines, which are like 10$ and 10 minutes to change, or it's the radiator, which should never cost anywhere near 1200 to replace. one of my cooler lines sprung a pinhole leak, I was able to drive 40 miles home without the temp light coming on. Do you have the truck with you right now? Is it still throwing the lights since you got it back? Check the alternator connections first, there should be two plugs and one wire with an eyelet bolted to the housing. Link to comment Share on other sites More sharing options...
Slartibartfast Posted January 12, 2018 Share Posted January 12, 2018 I don't think he's talking about the tranny cooler leaking coolant. There's some kind of bizarre oil cooler on the VQ R50s that transfers engine oil heat to the coolant (near as I can tell). Apparently the O-rings tend to fail and leak oil. If it's leaking coolant, either it's actually the hose that's leaking or the cooler's hooped. Looks like you can get one for about $80 on Fleabay if the cooler itself is bad. More on this.

XPLORx4 Posted January 12, 2018 Share Posted January 12, 2018 The leaking oil cooler (at the oil filter) is unrelated to any dashboard warning lights. Link to comment Share on other sites More sharing options...
Bax03SE Posted January 12, 2018 Share Posted January 12, 2018 Ive had a few VQ powered Nissans and all have had the oil cooler leak at the O rings. Its an easy fix, but no way its related to any warning lights. Link to comment Share on other sites More sharing options...
adamzan Posted January 12, 2018 Share Posted January 12, 2018 Yeah, the o ring is like 10 bucks from nissan. Had to change it on my parents maxima. 10 minute fix. Link to comment Share on other sites More sharing options...
