Scary!
OK...I've been working on overhauling the cooling system since last weekend and finally had a moment to post a pic and a story that was "eye opening" for me at least.
The MH is still new to us and while I've been working on getting most of the systems working I neglected to do a thorough review of the engine myself since I paid for an engine tune up and brake job when I bought it. I guess I assumed that the tech would have let me know if it needed anything else maintained or replaced. The coach was then driven nearly 1200 miles for me to take delivery so everything must be OK - right? WRONG!
While on a trip through the Cumberland Gap last week (I-75 in Eastern Kentucky and Tennessee - 4% - 6% grades) I finally got the temp light on at 225 degrees. I pulled over, let her cool down and then proceeded without incident. I knew early on that I would need to address the cooling system and had been researching the forum all week for solutions. This issue however convinced me to overhaul the cooling system as best I could; flush the cooling system, wash out the bugs and grit from the radiator, replace all of the belts and hoses, replace the thermostat and water pump, replace the coolant, run some of that Wetting Agent and replace anything else that looked scary.
After reading about what a nightmare it can be to change belts on the AS MH's I decided to pull the grill and radiator/shroud and really get at the belts, pump and hoses. What I found scared me. I've attached a pic of one of the best belts on the engine. Both belts to the boost pump where very loose; one was nearly worn away and broke when I pulled it over the pulley. On top of this the aftermarket trans cooler was leaking badly and when I changed the engine oil I realized that someone had left the drain plug in loose - it was about half way out! Any one of these maintenance issues could have been catastrophic to me, my family and obviously the AS.
All I could think about were those long climbs and steep descents in Tennessee the week before. We’re new to the AS and also to RV ownership but one lesson I’ve learned already is not to depend solely on the dealership or mechanic too much for general condition and roadworthiness. When I asked an RV mechanic friend of mine about this he mentioned that on an “AS IS” sale like mine there is no Pre Delivery Inspection required, so basically most dealerships do the minimum to get the unit out the door and across the curb. Now don't get me wrong. I don't blame the dealer, I knew what I was buying. I just forgot for a second that this is a 17 year old machine and I should have know better and checked it myself.
The good news is that after about $100 at NAPA, a lot of sweat and a few bloodied knuckles, we’ve been able to replace/repair everything in time for a little camping this holiday weekend. Cheap insurance and peace of mind.
