I have scrolled through a number of items on here and am still having some questions about this problem. I have a 2002 2.0 that suddenly is leaving the fans on. I just had the water pump and timing belt done about 4 days ago. today, the fans are now staying on and I cannot find a wiring schematic to know where the relays and sensors are for me to start trouble shooting. I have also noticed a two prong connector on a coolant pipe with nothing attached on the right side of the plenum...any help is appreciated.....I usually work air cooled so this is a new adventure!!!
