Tommy......

So what radiator did you go with?

I had Mac's build me a new radiator and now after 3 repairs under warranty, I am ready to scrap it.

This makes 3 new radiators and 3 repair at 104K miles. HELP! Anybody.

Thatís not good news for me. They warranty it for 1 year. Youíve had 3 repairs in 12 months? Can you give a little more detail with the issues youíve encountered?

I made sure to correct the bushing installation (will check when I pick it up next week).

What feedback have your received from Macís? Do they have ďlemonsĒ in the radiator world?

If TMan59 is correct and Mac's gets there radiator form Source Engineering in Eugene who orders through Radiator Specialties in Cali, then you should be good to go.

In 2014 Mac's built my radiator in there shop with copper core and steel tanks.
In 150 miles the right side tank to core failed (repaired by Mac's)
Another 1,500 miles and the left tank to core failed (repaired bu Mac's)
Another 9,500 miles and the core has a leak (repaired by Mac's)
Another 23,800 miles and the right tank to core is leaking.

After 36,000 miles of use, I am going to scrap it.

I am not alone as I know of 2 other Alpines with the same Mac's experience

Great... Well mine is manufactured by Macís. It will be interesting to see how they cover warranty with me being in TN and TX. I sure hope they cover labor required for removal and repair. Otherwise, this is going to get expensive...

I talked to Burke today and he sold his last radiator 2 months ago. What a nice guy!

So I got the RV back, $2600 in labor later. When talking with the owner and mechanic, they found my instructions for the bushings odd. I sent them the picture from c_oneill in post #16 of this discussion and told them that was incorrect and to install it opposite of that. When discussing this yesterday when I went to pick up, both of them said that the way it is installed in the picture is the way every other RV theyíve seen had them installed.

I guess Iím chalking it up to Alpines are a different animal...

Appreciate the info here, awaiting pricing for replacement rad, after learning the epoxy debacle and leaving the Alpine in CO (towed).


No evidence of leakage nor o'heatuntil o'heat up :Loveland Pass. "Jake-braking downhill cooled it but the it refused to stay cool; seems a sudden failure and Cummins Rocky Mtn, quoted $8k+ for r/r, cleaning and new 'stat, etc. My confidence in them is less than stellar, for a few reasons.

All said and done, I was about $3800 in the radiator itself and $2600 in labor and the few things I had them do.

Angry

Mor reasonable, indeed. I don't agree with RM Cummins and think they're ripping me off. Based upon a local Cummins expert, this isn't a radiator issue, rather a failure of the thermostat, a broken water pump or perhaps the fan controller.


Cummins estimates $2100+ just to change the thermostat, which might be an hour job. Their estimate, at $135/hr calls for 10 hours!

I could change it and the water pump, on the road with my emergency tool kit in under 2.
It's appearing that Cummins Rocky Mountain doesn't want to work on RVs, despite having a 'specialist'.

I didn't call Mac's, given the oinfo in this thread.


Reply from Source RV asked which of two engineering diagrams was correct. Really? Am I the expert, never having seen the unit?


Radiator Supp[ly House replied, asking the measurement between tanks!


With the Alpine 1500 miles east, it'd sure be nice to find someone knowledgeable in the biz!
