hello, I have a supercharged ap1 and have been having some over heating issues on hot days. Everything seems to be functioning properly but things are still getting hot. Was just cruising around 50mph in 4th and noticed 4 bars on the temp gauge.. Starting to think my radiator and fans just aren't up to the task. Running a mishimoto rad and spal slim fans. If it over heats just cruising around on a hot day, i don't even want to think about what will happen when I finally get to the track! need to sort this out asap! Any recommendations to keep my car at normal temps? Different rad? fans? pusher fans? Idk please help!

 

ensure there isnt an air bubble in the system, 4 bars on an ap1 is like 232F which is pretty f@#king high

 

Yeah 4 bars is bad! Did you replace the fan switch to a lower temp? I have the modifry upgrade and just switched to a Mishimoto, I also have a 175 switch. Because I have the modifry upgrade I have a good idea of when the fan should come on and due to the cooler temp coming from the Mishimoto my 175 comes on at a slightly higher temp now due to the cooler fluid hitting it from the radiator and the difference between the temp gauge and fan switch location. If you have the standard 190 switch it could be quite hot before the fan kicks on

 

well I'm running AEM V2 and the fans are set to come on at 187 which they do. I let it idle for awhile and watched coolant temps on the laptop. Pretty sure no air bubbles in the system. Everyone is telling me the mishimoto is junk and other people are saying they had over heating issues with this radiator as well. Looking to buy a dual pass radiator here and hopefully that will solve my issues. http://www.mrsideways.com/s2000radiator.html

 

does the bottom rad hose get hot? does your heater blow hot?

 

I have heard nothing but good things about the Mishimoto. Guys boost on OEM radiators and don't have issues, so I doubt it is that. I am wondering if you are not having head gasket issues? What type of supercharger setup do you have?

 

I have a new OEM thermostat and it's working properly. Heat blows hot. I was just monitoring ECT on the laptop and it hit 4 bars around 214. I'm just now discovering that when I have the AC on, temps rise fast and it brings me to 4 bars quickly. Why would temps raise so much with the AC on?

 

you have an ap2?

 

Ap1

 

I had a friend with a supercharged ap2 and an aftermarket radiator(not sure which one) and he had issues with it getting hot as well in city driving/stop and go. Replaced the fans with some more powerful ones and it was good to go. Apparently some radiators just need airflow to cool correctly
