While I am replacing my fan clutch, I figured I'd go ahead, re-replace the thermostat (180 degs), flush the radiator, pull it out, and give the fins a good cleaning too.

I don't have access to compressed air where I will be doing the work, so what would you suggest I use? Also, after I pull the fan/shroud, it just slides out, right?

Use some soap and brush. Be gentle as the aluminum fins will bend easy. Is your eec tuned for 180* thermostat? I changed mine back to 195* cause the fan was coming on too frequently (electric). There will be two brackets holding it in place on the top of the radiator on each side.

No, it's not tuned (it needs a good tune-up period!) It's been running way too hot lately and I thought I'd get things as cool as possible without going off the deep end (for now...)

LOL....I didn't mean the engine needing a tune-up. I meant the computer tuned to run with the cooler t-stat and colder plugs. That's what I've understood you need to run with that t-stat. You should back flush the radiator and engine, and even could use the water wetter product.
Is your fan functioning correctly?
What temp. is your fan coming on?
You may want to check the condition of your water pump to make sure it isn't corroded and therefore not pumping very well.

I think the fan clutch is pretty much dead. I'll be replacing it this Saturday. I'm not sure what the temperature it's running, but the needle will climb past the 'M' in NORM if I'm dealing with city traffic.

I'm doing these things as a "learn as you go" approach... I haven't even begun to think about tweaking the EEC. :)

remove the radiator, take your garden hose and spray the backside of the radiator. all the bugs and crap will be cleaned out from between the fins. then take the radiator to a shop and have them pressure test it.

you dont need a colder tstat, really. just do a few searches and see what you can do to maintain your cooling system.

Ok, I'll just leave the stat as is for now. If it is a new defective one, I'll swap it out later.

Will places like Auto Zone and Advance do pressure testing?

nope, take it to a shop. see if a general shop does pressure testing. what they do is plug up all the holes except one, and clamp an air hose of some sort onto one of the holes and they put the radiator into a large receptacle of water. they flip on the air and look for bubbles to track down leaks. it shouldnt cost much to test one.

Well, it's all done. Brand new fan clutch, bolts cranked down with Threadlock, thorough flushing of the radiator, and a hosing down of the fins as well.

I am now hurting in places where I didn't know I had places! :tongue:

I was all worth it though. On my ride home, even though it's not as hot outside as it has been lately, my temperature barely crept into the "N" and I ran Max AC full blast the entire way home.

I go take nap now. later. :D

My car always runs that cool with the a/c on...b/c the fan is always on. Atleast under 45mph. But with the air off, 95+ degrees outside and stop n go traffic, it'll get higher.

But glad to hear you got it straightened out!:wiggle:

I'm realizing now that it hasn't been working at the proper capacity since I got the car! Now when I start it up I can hear the reassuring roar of the fan, but I don't remember hearing that at all before fixing it.
