So very recently I noticed a little bit of coolant caking onto hoses connecting to the radiator (upper radiator neck?) on my 94' 325i. See the following photo -- any additional analysis is appreciated:
So I took the car into a mechanic and he said that I ought to be concerned about this since the radiator neck has a significant chance of cracking at some point. My cursory further research into it tells me to take him seriously (the plastic impaler situation and all).
I'm going to replace the whole cooling system (radiator and all) per his advice. I've decided to go ahead and try a DIY, even though I've never done a job that's anything like this before. But I want to make sure I am ordering all the needed parts. Using Pelicanparts.com, I found parts with the part numbers that the mechanic printed out for me. Does the following list of items sound comprehensive?:
-Bleeder Screw for Expansion Tank
-Thermostat Housing/Cover - Aluminum
-Genuine BMW Antifreeze, 1 gallon
-Thermostat 88 Degrees
What else will I need/should I buy to do the job? Pelicanparts.com makes it seem like there is more to buy. Is 1 gallon antifreeze sufficient? Should I get new radiator hoses? Water pump? Water pump belt? Mounting brackets? Rubber insulators? Do I need to buy any special tools (I have a pretty comprehensive mechanical toolkit already)? Any other miscellaneous things to order? I feel like I'm going to miss at least one essential peice of the puzzle. I want to do a complete job.
I'm gonna take my time and get myself up to snuff on the DIY tutorials for the job in the meantime.
But I appreciate the help! I'll make sure to keep everyone updated with the job itself after I order the parts and they come in...
