I have a 2008 GT. US Specs car, living in Dubai. I had a recent issue with a flat battery, I replaced that and wondered why that the cooling fan was on immediately after the battery was installed.....started fishing about and found there was a fluid leak eventually from the expansion bottle. I thought it might have been the water pump but since the expansion bottle there’s no water leaks. The cooling fan still stays on constantly. It used to cycle anyway on and off now and then but It’s 40 degrees here now and I’m just driving normally. It will get to 50 again soon. I’m having to pull the battery after every drive to get it to stop. The water temp is mid gauge at 195.... maybe thinking it’s the Relay? Anyone got any quick fixes or ideas? Thanks.
