Wow, What a Difference!!
I decided to clean my radiator by blasting it with the hose last week. Since I don't drive her everyday, I hadn't really had a chance to see the difference in the temps. All I can say is Holy $h!T, what a difference. In some situations, theere is as much as a 20 degree temp difference. I drove it one way about 40 miles, both open road and stop and go. I checked temps and I was around 201. Considering that it has been in the 230s during stop and go and now is 215 degrees is huge. On the open road it was running around 199-201degrees where it had been previously 220.
I wish I had done this months ago. I didn't remove the radiator to clean this but was able to open up the shroud enought to give it a good spray down with the hose.
Thanks to the forum members again for the inspiration to do it myself.

Let me make sure I understood you correctly.
You "cleaned" your system and it runs cooler??
No water wetter? No removal of the Thermostat? No lower temperature thermostat? No larger aftermarket radiator? No remote fan switch in the cockpit? No lower temperature fan relay??
I'm confused!!!!

When you allow air to flow through a radiator it actually starts to transfer heat. If he had it clogged up with road debris from years and years of driving then a simply cleaning could help dramatically.

Yes, I physically cleaned the radiator, the part in the front of the car with the aluminum fins. I was absolutely aghast at what came out. No wonder it was so damn hot. I didn't remove the radiator, I just opened up the shrouding enough to get a good strong spray from the hose. I sprayed from the engine side towards the front of the car. I was able to spray some Krud Kutter on the fins and let that set in for a while and then sprayed it with the hose again. No $h!t, 20 degrees cooler. Of course, that was the issue with my cooling system. Nothing else was wrong. Best thing I have done to the car yet.

That was the picture after everything ran down the driveway. You can see the dirt and debris that was all jammed up in the radiator fins. There was tons more that flushed down the drive.

i believe he was being sarcastic, because we always have tons of people looking for upgrades to make their car run cooler, when in fact a properly cleaned and maintaned stock system cools just fine. people seem to think you need special thermostats and switches and this that and the other to make these cars run cool. none of that is needed, just maintain what you have stock and you should be fine

sorry, I was being a smart a$$ all along
I've been in many threads whereas jokers stumble in all day long stating the the C4 is supposed to or designed to run 230°-240°.......pure BS
There is not an engineer in the world that would think that hydrogen embrittlement would be the desired result.....
http://en.wikipedia.org/wiki/Hydrogen_embrittlement
But one after another come on this board and claim your motor is supposed to run above boiling point on purpose.
These cars are decades old now with years of sediment build up.....
So many go straight to the extremes without ever considering that having their radiator boiled out may be the solution........Boiling your radiator out should be step one when you are having heat issues......not the final attempt.

in a forum atmosphere ther is no hearing of a voice for inflections in tone. It's ashamed that some people don't realize this. Then, of course, ther are the people who use the anonymity to be a$$hole$ on purpose. It's the normal people that make this forum fun to be on. Rock on Forum members, boo-hoo to the posers.

^^ya know, it is either or .......
Boiling out my '84 was ~$60 dollars benched.....and a new OEM was $100 plus shipping from thepartsladi
I opted for the new one and threw the old one out with the trash. Thepartsladi shipped the new one in the same amount of time the radiator shop told me that the could turn mine around.
$40 just didn't make enough of a difference to even mess with a ~20 year old part.
