Check with Cummins with your engine SN if the Cummins document shows it to be mounted on the engine. Check with Freightliner for your VIN if the Cummins document shows it to be remote mounted. Be aware that the correct filter depends on exactly what coolant you have (whether long-life or one requiring SCA). If coolant is original, Freightliner can tell you what coolant you have.

Raypat, Welcome to the FMCA Forum. Either a problem in the Allison ECU or just as likely an issue in the wire from fuse box to ECU. Before spending too much time diagnosing, I would run a new wire and remove the old one. If that doesn't address your problem, here is the guy to contact: https://www.transmissioninstruments.com/

Voted absentee today. Prop 5 FOR. Proposition 5 (SJR 24) “The constitutional amendment dedicating the revenue received from the existing state sales and use taxes that are imposed on sporting goods to the Texas Parks and Wildlife Department and the Texas Historical Commission to protect Texas’ natural areas, water quality, and history by acquiring, managing, and improving state and local parks and historic sites while not increasing the rate of the state sales and use taxes.” Explanation Proposition 5 would require the Legislature to allocate the money raised from state sales taxes on sporting goods (i.e., hunting, fishing, outdoor equipment) to the Texas Parks and Wildlife Department (TPWD) and the Texas Historical Commission (THC). Revenue from such taxes would be used to improve and manage state and local parks and historic sites, and to acquire new sites. Proposition 5 closes a loophole in the current law that prevents all the revenue raised by these sales taxes from being given to Texas Parks and Wildlife Department and the Texas Historical Commission, thus allowing some of the money to be used to balance the state budget. Arguments For State and local parks are essential to industries such as fishing, hunting, and tourism that benefit Texas economy. Proposition 5 would require the government to support this vital economic sector more fully. It would allow these agencies to make long range plans based on a reliable funding source. Many parks and historic sites of Texas are decaying, and new parks are needed due to population growth in the state. Proposition 5 would provide a sustainable source of funding for their preservation and new park development so they could be enjoyed in the future.

Actually, PRICE is the only reason for using anything but one of the new-generation long-life coolant. In linered or parent bore engines, basically 6 years-- put it in and forget about it.

Mike, I agree. A clogged CAC would merely limit heat transfer, so under higher loads, engine temperatures would rise more quickly than were there good air flow. It would not cause excessive temperature fluctuations under steady-state conditions (like I 10 across Louisiana-- for those not familiar with this section, it is FLAT-FLAT-FLAT). For peace of mind, might want to replace the thermostat (and gasket). It is either that or the fan clutch allowing/causing that much temperature fluctuation. As you can see, I do not think it is "normal" to have an 18 degree F temperature swing under steady state conditions. At least I would not find that acceptable. If the thermostat doesn't lessen the temperature fluctuation under steady state conditions, I would be on the phone to Horton engineers. Looking at this from another perspective, I would sure hate to be in the mountains and start up a long 6% grade with engine coolant temperature at thermostatic control PLUS 18 DEGREES F.

chrisc, Welcome to the FMCA Forum. If this issue occurs only on shore power, check all connections and cord ends between male shore power end and ATS or surge protector. Look for signs of overheating in the plug ends or other signs of a poor connection.

Well, algae can clog a fuel filter in any engine. But, modern diesel fuel systems have closer tolerances, so it is common to fit them with finer micron rating filters. Yes, a 2 micron filter will clog faster than a 5 or 10 micron filter.

mcentirejerry, Welcome to the FMCA Forum. First, is to verify that the IGNITION SOLENOID is working. Do all the other things that normally only work with the ignition on still work (like dash HVAC fan). Have you unplugged/replugged connections at the shift pad and Allison ECU?

Stu, How hot does it get? Has the fan clutch been checked/replaced?

Two points: I don't believe anyone is suggesting "inflating to the maximum" UNLESS (read that BIG UNLESS, and hopefully not the case) that is the PSI recommended by your tire manufacturer for your actual weights (plus perhaps a 5% fudge factor for safety). And, both tire and wheel PSI are for COLD PSI. Both tire and wheel manufacturers know that PSI will increase with temperature rise.

sangerm, Welcome to the FMCA Forum. Pull out your digital voltmeter and check voltage at the house battery(ies) and also the chassis battery(ies) when this happens. Winnebago is pretty good about supplying electric schematics. If voltage at the batteries is 12.0 VDC or above, follow "power out" from the positive side until you find where you don't have it any longer. May be resetable breaker, may be bad connection, may be a solelnoid-based isolator switch (controlled by the "salesman switch". Your coach electrical schematic is where to start.

Lyle, You must be WAY far north to already have #1 diesel at the pumps. PS makes a number of different diesel additives. Make sure you used their anti-gel is you had much #2 diesel in the tank. If you are asking for a ranking: 1. Best drive occasionally, but only if you can drive at least 25 highway miles. 2. Second best-- let it sit. 3. Worse-- start the engine and let it idle. That WILL add moisture to the crankcase.

lpigula, Welcome to the FMCA Forum. If you already have diesel in the tank (i.e. not winter grade diesel) go by a Walmart and get P/S brand diesel anti-gel. Also, a very good idea to add a BIOCIDE such as Biobor JF to prevent algae growth. Then drive it enough to completely mix and than top off the tank with diesel. This will minimize condensation in the tank. ONLY start the engine if you can drive 25 highway miles (a very good idea). It takes that long for the oil, not just coolant to get up to temperature. Running the generator once a month is a good idea-- be sure the load is at least 50% of rated capacity.

Look at the "reaction time" (which I am seeing as much longer than the quick reaction time of many of the side radiator hydraulic controls) and compare with what you see for coolant temperature change.

windsport2018, Welcome to the FMCA Forum. I would contact the factory for their recommendation: https://www.centramatic.com/contact.rhtml

You could post in Type A or if you are considering custom modifications to address it, in Modifications.

Chris, Is this a Workhorse P chassis and you are referring to the air bags that are inside the front coil springs? Workhorse W chassis? Rear supplemental air bags? Same tire pressure (based on actual weight)? How many miles--worn suspension components/ shocks? Lots of things go into determining ride quality.

Mike, Looks like the picture is of the center of the CAC. It will be clean, even if the rest is clogged-- see the picture I posted above. The most likely place for it to be clogged (and also one of the harder to get a good look at is the lower perimeter.

So it is a VARIABLE SPEED, not LOW/HIGH SPEED fan clutch? Have seem that with hydraulic side radiator, but not rear radiator configurations. If you would, please post the brand/model of the fan clutch on your coach. Inquiring minds want to know.

Beaver42, How many hours a day are you willing to drive? Interests? Kids? Said another way, what things to ya'll enjoy doing/seeing??

ruffis, Welcome to the FMCA Forum. I am confused by the mixing of discussing battery draw with 120 VAC. I assume the 20 amp draw was on your 12 VDC system. So, chassis battery or house battery? I would start to isolate that draw (which is HUGE, BTW) by asking Jayco for an electrical diagram to determine what is on that circuit. With 20 amps, my first guess would be mirror heaters if you have them. Again, the GPS is 12 VDC (I assume), so can't see any relationship between the 120 VAC ATS and the 12 VDC powered GPS. Please keep us posted on what you find.

What does voltage read at the house batteries? Are you plugged into shore power?

Actually, the GVWR placard states the correct minimum PSI for an axle loaded to its Gross Axle Weight Rating. That may or may not coincide with the maximum allowed for the tire or rim. If he is loaded to GAWR (of 1/2 of GAWR on one side) then he is OK adding a little to it as long as it does not exceed the tire or rim PSI rating. Let's hope he is just wrong, not overloaded!
