Changing plastic fitting between bypass hose and intake
For the last week or two I've had a slow coolant leak. First I checked the water pump and it seems fine. Following the trail of green sludge, I swung the alternator up out of the way and pressed on the bypass hose where it meets the intake... glug glug glug, coolant came pouring out.
I seem to have the crummy plastic fitting that goes between the hose and the intake. Do I have to drain and refill the cooling system in order to change the fitting? How much coolant is going to come pouring out when I disconnect the hose? Obviously I don't know much about engines but I'm learning... I'd never even removed a belt before today.
Two more questions:
1) Anyone by any chance know the part number for the new metal fitting that replaces the plastic one?
2) Anyone know where I can find a diagram of the 3800 engine? My Haynes manual give step-by-step instructions for how to replace parts, but it doesn't have a good overall diagram of the engine.
