Was browsing Winne web site last evening looking at 'preview' of 2008 Vectra. Reading the specs, noted listing of 425hp Cummins with rear radiator. No mention of side rad option.

Checked with a trusted source at Winnebago today and was told, indeed, there will be no side radiator option on 2008 Vectra's.

What in the world were the product designers thinking about when they came up with that bright idea For me, one of the huge advantages with the Vectra/Horizon has been the side radiator. It stays cleaner, maintenance access is easier (which means cheaper), and you get a variable speed hydraulic fan instead of a direct-drive fan.

Oh my goodness!

This sounds like another chapter in the constant battle between design, engineering, marketing, and last but not least, the bean counters.

Doesn't the radiator location come from the chassis manufacturer? Or are we saying the chassis people put it where Winnie tells them?

The MH manufacturer can order the chassis to their specs, within certain limits.

I was certainly disappointed. Hope that this is only a temporary situation. Our next rig will likely be one that we keep well into retirement and I don't want my next pusher to be a rear radiator configuration for the reasons John stated.

Not sure why Winnebago decided to make this change on their flagship coach, especially in view of the other potentially good features of the new Maxxum chassis.

I read somewhere in this forum that for '08 the CAT C7 was being delivered with a radiator fan clutch configuration, which should improve mileage.

Is this true for the new Vectra with the Cummins engine?

We took the ride and drive in a 08 Vectra at GNR on the new Maxum Chassis. Everyone that drove the unit commented about how much better it rode and drove compared to thier current Diesel-Pushers. To me it rode and drove better than our Suncruiser.

My point here is that the host said that by moving the radiator, they incresed the mileage by 1 MPG.

I also took the "ride and drive" in a 2008 Vectra at GNR. I was told that the side radiator hydraulic system drew 13-16 hp and was running essentially all the time. Whereas the new rear radiator with declutching fan that runs only when needed averages 1 to 1.3 mpg fuel economy improvement. This more than compensates for the negative effects of the particulate filters required on the 2007 and later motors.

Let's just hope they designed it better than Mine!

I can say I will NEVER have another rear radiator, period. In fact it is really my only major gripe about this unit!

Our cooling fan does not run until the coolant is at 215 degrees.

Sounds like you might be the victim of some marketing 'euphoria.'

We recently bought an 04 Meridian [rear radiator]. We had cooling problems until the shop cleaned the intercooler and radiator. Now, it runs very well, cooler than ever before.

If our coach had a side radiator, we wouldn't have had a partially clogged radiator. Seems as though a 'slobber' tube redesign could leave us rear radiator coach owner's with a better choice and still improve fuel economy.

John,

You are probably right about the "marketing euphoria" but what I was referring to about "running all the time" was the hydraulic pump for the side radiator, not the fan itself. I would guess the pump is similar to a power steering pump.
