RE: Ford 460 motorhome running hot

"As a result of this, I am a believer in using only distilled water with a radiator." Assuming that you mean distilled water MIXED 50%/50% with the appropriate antifreeze/coolant? (see owners manual) Using deionized, RO (reverse osmosis) or, bottled drinking water is also fine as long as it is mixed with the appropriate coolant. Stay with only distilled water, bottled water can have minerals and DI or RO can have contaminants if not handled perfectly. Oh please. So it's good enough to drink, (actually preferred) but not good enough to put in your radiator. Yeah right. Where did you take your chemistry classes? That's what I thought. What do you think happens to distilled water when it comes in contact with common metals found in any cooling system? (rhetorical question) You need not answer. Chum lee

RE: propane campstove

"Why would a propane campstove produce more CO than a propane RV stove? Or, for that matter, a propane stove at home?" For a similar sized burner, it won't. The problem is that over time the burners get plugged with debris so they aren't in proper adjustment. That's when the carbon monoxide can rise to unsafe levels. Your campstove manufacturer has deep pockets and must protect themselves legally (financially) in the event of a lawsuit. It is designed to be used outside, hence the name "CAMPSTOVE." They placard the appliance that way and warn the users several times NOT to use the stove inside and not without adequate ventilation. That said, eventually someone decides to use it as a heat source or for cooking INSIDE. For example, in a tent when inclement weather is present. They end up seriously burning or killing themselves and then they try to blame the manufacturer for a defective product. It happens all the time. Hopefully not to you, IF you follow the warnings/directions. Chum lee

RE: Rewiring Trailer Brakes - How to Allow for Axle Movement?

Make sure you use the appropriate shielded wire anchors spacing them frequently along the run. Use strap ties to hold groups of conductors together. Allow plenty of wire in the flex areas and secure each end using the appropriate connectors. Whenever the wire changes direction, place an anchor at the beginning and end of each radius. Do not bend the conductors sharply. When the conductors are subject to flying debris, heat, moisture, dirt protect them with an additional corrugated plastic shield. For examples of what to do and how to do it, just look under the hood of any trucks with factory wiring. You'll immediately notice the difference between that and when trunk monkeys have been at work. Do it like the factory to minimize future issues. Chum lee

RE: Ozone to clean fresh water tanks

Since I full time, I also have not sanitized my fresh water tank in 20 years. There is more than enough chlorine in city water connections to keep the tanks clean day after day after day. They key is USING THE WATER UP and replacing it in a timely manner. Chlorine dissipates over time, as it works. Similar to a swimming pool which constantly needs fresh chlorine, (mostly due to sun exposure) your fresh water tank needs new FRESH chlorinated water REGULARLY to stay bacteria free. Once the bacteria gets established, it takes a larger dose of chlorine to knock it out. Ozone works too and it also depletes over time. Chum lee

RE: shutting down generator with air conditioner running

Best practice shut down the air conditioner. Wait a while (5 minutes) and then shut down the generator. The same applies to large inverters. Agreed. Not doing the above once or twice probably won't be the end of the genny. It will just make the end eventually come . . . . . sooner. How much sooner? I don't know. Do you feel lucky? The reverse applies for cold starting. Start the genny. Let it warm up a few minutes, then load 'er up. Chum lee

This did nothing and I do not believe it can attack sediment issues. Waste of money." Agreed there. Most over the counter radiator flush additives are worthless if you are trying to dissolve hardened internal radiator scale. They work if you get oil/fuel/ATF in the coolant, but, so does flushing with soap and hot water. Save your time/money. Chum lee

RE: White smoke from exhaust

What does the smoke smell like? Fuel? Coolant? Other? Is it oily (like smoke) or does it evaporate? (like water/moisture) Chum lee

RE: Sticky front of oven

"The front of the Apollo half time oven is black- maybe plastic. No matter what I clean it with it stays sticky and looks streaked and nasty." The following only applies if the oven is ceramic coated metal. (not plastic or painted metal) Use caution on adjacent painted/plastic surfaces and laminate counter tops. With adequate ventilation, solvent based cleaners like Brakleen, hexane, acetone, MEK (methyl ethyl ketone) toluene, xylene will cut through the oxidized grease better than household cleaners. Most of them are HIGHLY FLAMMABLE so beware if you are inside. The fumes MUST clear before lighting the range/oven or anything else. Use gloves and lots of clean paper towels and the grease will clean up quickly. The above cleaners are available at Walmart, Home Depot, local auto parts stores, etc. Chum lee

RE: Onan 5500 Backfires and Dies under a load

If it started suddenly, I would bet on a broken valve component- spring or rocker arm. Yes, I've seen that (and/or a tight valve clearance) on 5.5, but IMO, it would happen all the time, even when cold. How does that explain this: "It began backfiring and then dying when a load was placed on it. . . . . . until it dies then gives an overheated exhaust code." I'm assuming that later after cooling off, it runs (semi) normally when warming up and NOT under load. A compression check and a look at the valve train/clearance is in order. Interesting issue. This is a NEW generator! Chum lee

RE: Ford F53 Suspension

Sure. Inspect/replace any/all worn bushings with new parts. If they haven't been replaced, chances are your shocks are tired and in need of replacement. Have the alignment checked. Put the suspension back where it "was and should be" when it was new before you start to modify anything. What do you mean, specifically, when you say, "improve" the ride. Chum lee

RE: Onan 5500 Backfires and Dies under a load

"I assume from the backfiring?" I can't see it or hear it run online. That said: Backfiring implies that unburned mixture IN THE INTAKE tract is being ignited and burned. (not the exhaust) Can you confirm that? Backfiring is a classic condition of a lean mixture which would point to a vacuum leak somewhere in the intake. Are all the breather hoses connected properly? Is the (new) carburetor properly seated on the manifold with all the gaskets? When hot, a lean mixture can lead to pre-ignition/detonation which may sound like a backfire. What happens if you manually force the choke on with the engine warmed up, loaded, and backfiring? (richen the mixture) Any improvement? Do you have a compression tester? If so, does the engine meet the compression specs? Chum lee Chum you might be a bit over my head, LOL... I will ask him to try and manually adjust the choke when its backfiring. No compression tester. OK let's try something simple. Your carburetor should have an altitude compensating adjustment screw. It has some control of your fuel mixture adjustment which should be set for your current altitude. It that set correctly? Having it set too high for your current altitude can create the symptoms you have. For example: If you are currently at 1500 feet altitude, adjust (turn) the screw so that the pointer is between 1,000 and 2,000 feet. Look at the screw adjustment on the carburetor, it will be obvious. Chum lee

RE: How High???

12 feet 6 inches loaded, just have to say everyone should know the height of their RV! Especially if they frequent this location: https://www.youtube.com/watch?v=USu8vT_tfdw Knowing the height of your vehicle is a moot point if you don't/can't read the signs! Chum lee

RE: 2006 Grayhawk Ford e450 v-10: Power increase

Leave everything you don't need at home. Travel alone. Dump your black/grey water tanks prior to leaving home. Fill your fresh water tank when you arrive at your destination. Unless you are willing to spend more than your RV is currently worth, learn to live with the power you have. Chances are you are at or close to max gross weight, so, reducing weight is your cheapest fix. Sorry, that's the best I can do. Chum lee

RE: DP side mount radiator is aluminum or copper better?

As long as you use the right coolant and maintain it regularly, IMO, for heavy duty trucks, copper-brass (tanks) on copper-brass (tubes) on copper (fins) win, hands down, every time. They are heavier, generally repairable, more expensive, (than aluminum) and getting harder to find. (and no, I'm not dissing aluminum radiators) If you're worried about the warranty, IMO, you are buying the wrong product. IMO, a well built brass radiator, well maintained, has a life span measured in decades. If you want to low ball the price, then you NEED a good warranty and roadside assistance! Chum lee

RE: Model of WH in 1998 Southwind?

My 99 Southwind Storm (Class A) has an Atwood GC6A-7E 6 gallon gas/electric water heater. AFAIK, that was the standard/stock water heater that came with the MH. For electric use, the heater has a 120V cord that must be plugged in to a separate remote outlet not provided on the motor home. If you can open the cover panel, the ID plate is inside. Chum lee

RE: Fuel cleaner/additive for Onan generator

IMO the best additive is new clean fuel, regularly, run through the fuel lines and carburetor. That means running the generator about every month for long enough to burn out the old fuel, then, get it warmed up and put it under +-3/4 load for a few minutes. (20 to 30 minutes total run time) You can add Sta-bil, Seafoam or something similar to your fuel tank, if you want, but, IMO, running the genny, . . . . regularly, is what keeps it going reliably, with minimal fuel issues. You can drain the fuel and run the genny until dry if you know you aren't going to use it for a while. (like 6 months) Leaving the same gasoline, especially E10 or higher in the carburetor for over a month is the beginning of problems down the road. Chum lee

RE: How to prevent sidewall yellowing?

Ultra Violet light (UV) is NOT your friend. Avoiding it is the best policy but not always possible when you are outside. Using a quality marine/aircraft grade polymer (non-wax) protectant frequently does help. They are expensive, but, they work. I'm not promoting this product/company specifically, but, regularly using something like it is a step in the right direction. https://www.nationalsupplydirect.com/303-aerospace-protectant-gallon-refill.html?gclid=EAIaIQobChMIpsiK7In-4wIVjxitBh0m7QSsEAQYAiABEgIawPD_BwE Chum lee
