Then temp kept climbing, and in an instant, the temp went to zero, smoke started pouring out of the engine bay, lost all power. Then the temp gauge surged to 225, and I was panicking, looking for an exit or anything safe to pull over. There was no safe place to pull over, so I pressed on cautiously. Then once I was in the very hilly portion of north Texas, temps started coming up agian. For the next two hours, had to pull over two more times and repeat. Checked coolant, and due to a bad gasket on the coolant overflow, some coolant was present in the engine bay. Dash temp gauge reached 215ish, so pulled over, and let cool down. Since day one, the coach overheated anytime the temps were upper 90's, so I was very nervous and watching the gauge like a hawk.ġ5 minutes after departing, the overheating began. On last trip attempt (In the middle of Texas summer), outside air temps were above 100. Since the coolant light was on always since the used coach was purchased, the only way to monitor was to watch the engine temp gauge. Kysor Coolant Level Alarm 1039-07058-01 Monaco (1).pdf This is the last warning light I have on my dash, I really want it fixed!!! So all the old pros here, please chime in with your suggestions. But the problem came back after 6 months. Someone even experimented with changing diodes on the CLA circuit board with limited success. So I am amazed there are no permeant solutions for this problem! Recently, I blew my engine up, due to not having real time low coolant monitoring. It has to match the CLA module installed on your coach. THIS WILL NOT WORK, no mater how you try to wire it. I bought the Volvo tank latest replacement probe, and it had two wire hookups. (Hit &Miss), but know that there are no aftermarket/OEM updated parts for the 1 wire probe. If you go to Monaco's website for parts, you may be still able to get one. My group of Dynasty owners, have been trying to solve this problem for almost three years now. There are YouTube videos of how to clean it, but the problem will keep coming back. The probe is located on the top of the plastic coolant overflow tank. I guess I just figured it'd be a probe given all the fancy electonics found in a Sprinter? vicĢ0140714 edit: The T1N Sprinter uses a float switch, not a probe.This is a problem on all the older Monaco's.Ĭorrosion builds up over time on the in-tank metal probe. I may take a look at the overflow tank tomorrow and see if I can see anything. I couldn't verify whether the Sprinter uses the float design. Please note that the sensors supply fixed value resistance (180 and 120 ohms if i remember correctly) when open, and a short circuit when closed - so they do not behave as a pure "switch".Įxperienced benz repair shop will perform the above procedures and find the faulty component quickly. Things to check is the coolant level sensor (inserted in the lower part of the expansion reservoir), the washer level sensor (in the left front wheel housing, towards the bumper, easily accessible after removing front left wheel and folding the black plastic liner) and the wiring if the sensors check out okay. Malfunction in one of these components can lead to displaying the low coolant warning, even though the coolant is OK and the sensor may be also okay. The W203 (as many other Mercedes series) has funny circuit for monitoring the coolant level - it is connected in series (!) with washer fluid level sensor. The float in my tank is bad and it drops right to the bottom even though the coolant level is fine. When I read about how the coolant level sensor works (magnetically in conjunction with the float) I realized that I had to order a new expansion tank. I still don't know for certain, but apparently MB uses a float type sensor in some vehicles. I ASS-U-ME'd it was just a probe, but it very well may not be.
