Caesard Posted July 7, 2013 Share Posted July 7, 2013 I was on my way to football today with my son, and as the temperature in London was above 26°C, i put the air conditioning on. After a couple of minutes, i decided to take a look at the temperature gauge only to see it in the extreme red. I then decided to pullover and open the bonnet and steam was pouring from the expansion bottle. After allowing it to cool down, i sourced some water and filled the now empty radiator and continued on my way, this time without the aircon. What can possibly be wrong as it has never done this before even after installing the FMIC. I am BPU with a greddy 3 core fmic, a near new, never used before stock radiator and aluminium top radiator pipe. Only on putting the aircon on did this happen.

Littler Posted July 7, 2013 Share Posted July 7, 2013 What's the condition of the aircon rad that sits between the FMIC and normal rad? Link to comment Share on other sites More sharing options...
Pixelfill Posted July 7, 2013 Share Posted July 7, 2013 Has the weather been this hot since installing the FMIC? We're you sat in traffic or making good progress? Link to comment Share on other sites More sharing options...
Swampy442 Posted July 7, 2013 Share Posted July 7, 2013 How good is the viscous fan unit? Was the a/c fan working? Link to comment Share on other sites More sharing options...
dude Posted July 7, 2013 Share Posted July 7, 2013 Dont see too many FMIC installs with the stock AC fan in place, ideally wants a small aftermarket jobbie if you use the AC a lot. Link to comment Share on other sites More sharing options...
Caesard Posted July 7, 2013 Author Share Posted July 7, 2013 The aircon rad is also relatively newish. The viscous fan is new feon toyota, as i changed it along with my water pump last year. I dont know if the aircon fan was working as i was driving, but i have seen it working some time ago. I was making some progress, as can only be done in London, start and stop each minute at traffic lights . It is baffling. Link to comment Share on other sites More sharing options...
dude Posted July 7, 2013 Share Posted July 7, 2013 Little tip, if you think its getting hot switch the heater fan on hot and full it will cool it down a bit, if its blowing cold you have no water or your pump impeller has fallen off or some of the teeth have.

Guest Eddie_r32 Posted July 7, 2013 Share Posted July 7, 2013 whats the state of your rad like? the fmic will restrict the airflow to it and the aircon rad will chuck out some heat Link to comment Share on other sites More sharing options...
Caesard Posted July 7, 2013 Author Share Posted July 7, 2013 I will check and see what i can change to rectify this. Thanks for the heater advice Dude. Link to comment Share on other sites More sharing options...
listy Posted July 7, 2013 Share Posted July 7, 2013 Mine got a bit hot yesterday whilst playing with a Cayman S, and the rad is a bit low now. I'm going to flush and replace all the coolant tomorrow anyway. I put it down to hard driving and hot weather though. A new radiator is on my "To Do' list though.

Caesard Posted July 7, 2013 Author Share Posted July 7, 2013 Do all these aluminium radiators have any effect? I thought i heard that the OEM ones are better. Link to comment Share on other sites More sharing options...

I have a stock cooling system, with a FMIC.. Not having any issues.. It gets very hot in South Africa, so I use my A/C almost all the time.. In saying that I have a new rad/viscous fan/water pump..
