Rlwitt Posted June 9, 2021 Share Posted June 9, 2021 2008 Monaco Camelot. Replaced the plastic surge tank with a metal tank. About 10 mins after starting the Warning light came on. Continued to idle to get pressure up. No leaks and not running hot. Warning light still on. Any suggestions. TIA Link to comment Share on other sites More sharing options...
Dr4Film Posted June 9, 2021 Share Posted June 9, 2021 Make sure your coolant level sensor is wired correctly and working correctly. Link to comment Share on other sites More sharing options...
knightmovesrv Posted June 9, 2021 Share Posted June 9, 2021 obviously check fluid level and then low coolant sensor and connector. We have 07 Knight and installed Talon tank which came with new sensor and had no issues. To test sensor unplug and check light, then jump the wires and check the light. One of those 2 modes should put out the light if the sensor is the cause. Link to comment Share on other sites More sharing options...
JDCrow Posted June 9, 2021 Share Posted June 9, 2021 Is there just 1 light for “low coolant” or another light for “temperature “ I’m more curious as OP just said “warning” light 1 Link to comment Share on other sites More sharing options...
Rlwitt Posted June 9, 2021 Author Share Posted June 9, 2021 I installed a new sensor with the new tank. I will unplug the sensor and check the warning light. Fluids are good. Knightmovesrv suggested jumping the wires. Can you explain that more. Which wires to jump. Thanks for comments Link to comment Share on other sites More sharing options...
JDCrow Posted June 10, 2021 Share Posted June 10, 2021 I assume tie the two wires from the coach together (jumped) to make sure nothing is wrong from the sensor back? That way you can isolate a bad sensor Link to comment Share on other sites More sharing options...
jacwjames Posted June 10, 2021 Share Posted June 10, 2021 Do you know what sensor you installed. When I replaced my tank I used the plastic type, similar to the original. I used Ford sensor which is a 2 wire sensor. I just put the two wires together and then attached to the original sensor wire. I believe the system uses a Kysor low coolant alarm modual which actually senses ground through the coolant system. If the coolant level falls in the tank the Kysor module not sense ground it sends coolant alarm. Here's a link to info on it https://www.wanderlodgeownersgroup.com/downloads/KYSOR ALARMS SERVICE AND INSTALLATION.pdf So for the system to work correctly the coolant level has to be above the coolant sensor.

Rlwitt Posted June 11, 2021 Author Share Posted June 11, 2021 Vuerink in MI Update: apparently the sensor was the wrong one even though it was a 3 prong. Vuerink said it was right according to computer. Took coach to trucking center today. Code is for that sensor. It seems to always read low and set Warning. They found what appears to be the right one at Cummings in San Antonio. We’ll know tomorrow if it works 1 Link to comment Share on other sites More sharing options...

I bought the sensor from Ford, but Veurinks sent the wrong pigtail. They sent right one and took other one back no issues. Mine was only 1 wire pigtail in coach and new sensor was 2 wire. Simple crimp and she works great Link to comment Share on other sites More sharing options...

jacwjames Posted June 11, 2021 Share Posted June 11, 2021 When I first bought my coach it had a slight leak developing and I successfully repaired with Gorilla poly glue, which held for +5 years. I then decided to go ahead and replace. In ~2014 I just replaced my with the same style but the new version is a better version of plastic/nylon. Mine still looks like new. One advantage is you can see the coolant level versus just having a sight glass. I bought mine from Guaranty RV who had the best price at the time. Bought the fittings at Lowes and the Ford sensor off Ebay. https://www.guaranty.com The original sensor on mine was a long probe that fit down through the top. The sensor I replaced it with was a FordXC4Z-10D968-AA https://www.ebay.com/itm/363303882231?epid=1311200436&hash=item5496994df7:g:Sd8AAOSwSUBgNthP The origianl sensor was a one wire, and as stated earlier, it sensed ground through the coolant. To test the sensor just disconnect the wires, which should break the ground and the alarm goes off. Take a wire from ground the the sensor wire and it should shut the alarm off. The Ford Sensor is a 2 prong type, the sell a wiring harness but I just used 2 small spad connectors and connected 2 wires and then connected to the original 1 wire. I used silicone to seal the where the wires go into the senor. The change was not hard. Veurinks shows they have both the metal and plastic tanks. https://shop.findmyrvparts.com/searchresults.asp?Search=tank&Submit= Source engineering may sell them but not listed on their website there is a video of at the bottom showing the tank, but there have been reports of poor welding on these tanks. http://sourcerv.com/ Talin use to make them but it won't bring up the link, you can give them a call http://talinman.com/talin-vector-coolant-surge-tank/ Link to comment Share on other sites More sharing options...
