Two questions: Do you have AC and are you using it?
2nd Question, if you do not have working AC do you have the AC aux fan? Put a switch in to permit you to manually turn it on so you have more airflow through the rad. Also a suggestion to make sure that the main rad fan is working correctly. Fluid coupling OK? Another possible answer if you only have issues during really hot times is to put in a simple system to spray some water onto the rad. I think some people have used a windshield washer setup with a pipe accross the top of the rad with small holes drilled in it. Turn on the pump and spray some water onto the rad - should help bring temperatures down somewhat. Drag racers used something like this to cool the engine after a run down the track. I am sure I saw this in a Car Craft mag years back.

That was last fall I think. Well I've been driving without it (probably 10,000 miles or more) since then and nothing terrible has happened. Except lately the temp has been unacceptably high. Hardly a shocker since we're in the middle of a heatwave. With the outside temp in the mid to high 90's I couldn't really drive over 65mph for any prolonged time as the needle would rise perilously high (who knows how hot exactly, above the 100C mark anyway) until I wussed out and slowed down. Well rather than put in the new oil cooler I noticed a wet spot on the lower radiator hose and yesterday while I was running errands I stopped at the local CarQuest to see if they had the hoses. They had the upper and got me the lower today. Had a radiator cap too, made in Mexico, nice looking cap. The one on the car is so corroded I can't read it anymore. I put it on 6 or 7 years and ~70,000 miles ago... I was surprised how little coolant I lost in the replacement, no big whoop. I guess its mostly full of G05 now, I've been doing a "running project coolant change" changed a bunch when I did the water pump (and as it leaked just before I did the water pump) and more now. What came out was pretty yellow. Took a little ride and it rose more than I liked, could be just needing to burp though, I'll add more once it cools off and see how it does tomorrow. If its still real hot I'll put the oil cooler in. If the red car were registered I'd just drive that until it cooled off again, we won't be at these temps for too much longer. ;) Heck I may put the new oil cooler in no matter what just since I've got it. Or not, it depends on how hot it is Saturday. -Curt _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
