I have a 2004 Toyota Corolla, which currently has 101,xxx miles on it. I want to replace the radiator hoses, which are original and now feel old and squishy. I also want to replace the thermostat at this time, since it’s never been changed.
According to my Haynes book, it is necessary to remove the alternator in order to change the lower hose, though I fail to see how that provides any advantage unless I was to also discharge the A/C and remove the compressor (which I’d rather not do). It appears that I can remove the splash shield in that area, though I’d probably have to remove the cooling fan in order to have enough space to work.
The directions for removing the upper hose and thermostat body are even weaker, as they skip from draining the coolant and removing the accessory belt and alternator to removing the bolts on the thermostat body. Obviously, I need to get access to this area in order to do that. Am I supposed to remove the throttle body and associated wiring harnesses?
I am sure that someone here has either done this procedure on their own (similar) car, or done it for a customer, and I’m sure there’s an easier way. Any ideas?
