When I'm stopped the temp goes up some but comes right back down as soon as I start moving again or the first fan kicks on low. "

    "Yeah...I don't have those fan swicthes on a 96. I think its all computer control based on the ECM's temp sensor in the water housing.

    I'm not too worried about it. If I idle for a LONG time it will finally get to 204F and kick on the first low speed fan for a 45 seconds or so until temps get down to about 196F. As soon as I start moving temps drop back down to the low 180's when its 85F outside. "
    If the fans dont turn on as often as before with a stock radiator it doesnt really have any detrimental effect on the car. Operating temp might be a little lower but thats OK. My car does the same thing, MB. My fans never turn on unless I am at idle for over 5 minutes or so. I dont have an accurate water temp gauge but I have logged my coolant temps during crusing and they are in the low 180's just like yours.

    My install went without any problems but just took some time to get things right. As like other have said, WATCH OUT FOR THE BOLTS ON THE AC CONDENSER. Overall, the process was easy and went very well. I am in Arizona so I know all about hot weather unfortunately.

    Ah that sucks man. Yeah we used a rubber mallet and softly moved the condenser so we had no clearance issues.

    Is that condensor bolt a second gen thing. I will be installing a koyo next week and have pulled the radiator in and out more times than I can count. Can't think of anything like that.

    Yeah its more of a second generation issue but I would still make sure you have clearance if you have a 1st gen.

    Check out 3SX's site which shows pictures of the AC condenser bolts sticking out.

    Mine actually had a point on it. If I wasn't paying attention it would have easily poked a hole in it.

    I had my cooling system pressure tested (24psi) just about month ago no leaks .
