Brett - Do you know if your coach has two pumps? Wonder if the 36' CC's got by with just the one?
We have two on our 40' Allure. Rear started leaking on our way South from Alaska. I pulled into a shop to ask for some help bypassing it (Figured by the time I bought the hose, clamps, and a few more tools to do the job (IF I could get up to it from underneath - as I'm not as nimble as I once was
!), I'd be into it for just a little under what a shop would charge. And another factor, was we were still 5 hours out from our stop that night, with a non refundable deposit
Anyways, the shop foreman of a truck repair shop, said no way they could get me into one of the bays. Said they had commitments to get the trucks I could see in the bays, and three others, back out to the companies that same day. But, he said if I'd be willing to wait, he'd at least get someone to look things over to confirm it was the pump. About 30 mins later, he came out himself with a crawler and flashlight and a pair of clean working overalls (With two or three of his crew looking out from inside the shop.) Asked me to raise the coach so his belly could clear (His words, not mine!) the under frame. He slid under, looked things over with the flashlight. Hit his ear piece blue tooth and called his own shop. Ask the receptionist to have Jr bring him a flat blade screw driver, and a (Forget the size.) socket wrench. Few minutes later, Jr delivered the two tools. And this gent proceeded to grunt, and groan his way up to reach the water pump. Snugged up on some clamps, dried things off with a rag. Then rolled out.
He said his opinion was that it was leaking from an upper hose clamp, and running down over the pump body to make it look like the pump itself was leaking. Had me start the engine, turn on the heater, and said he'd be back in 20 minutes. 35 minutes later he was back out, I turned off the engine, he went back under, and I looked in from the engine bay access hatch. With a bright flashlight, you can just see the pump with the ISL combo.)
Bone dry, no more leak. I checked my coolant tank and it was still in good shape fluid wise. (Had only been leaking a short period, I spotted it as I walked the coach during a fuel stop.).
Took me almost as long to talk the gent into agreeing to take some funds for his time. He chuckled, and said it was worth it to him to have his crew see he could still do stuff!!! It being a Friday, I asked him if he and the crew ever had a few brews at the end of the week. And well, you know, he said they'd been known to do that
! So, went across the street and bough them a case of beer that he said they enjoyed. (Was not Molson, Ehhh!) From when we stopped, until when were headed back out, just about 2 1/2 hours.
It was two years later, in Sedona area, when mine started to leak at the actual pump itself. So, used the hose and clamps we had with us for such an occasion, and another gent charged me 30 mins work of labor to bypass the pump. Still sitting where it was. We saved the coolant that came out, and filtered it back into the tank. Doubt we lost more then 2-3 OZ's for the job.
And, having traveled in mid to upper 20's, our front OTR heater still keeps us warm in the front. The front pump is doing all the work, and I've detected no reduction in heat.
Best to all,
