>>I wonder what that does to the life of the rubber windshield trim and rubber wipers ?<<

Actually Frank the wiper arms lift at speeds over about 70-80mph so if one stays in that range the wiper blades aren't in contact with the hot widshield and are being air cooled ..for longevity.

Of course having a spare set of wiper blades around for that eventual replacement once every 10-15 yrs or so, might not be a bad idea. But then that gives rise to the question, what about 20 yr old tires?

Early Porsche 928's (pre-87 model year) are also like this.

"I wonder what that does to the life of the rubber windshield trim and rubber wipers ?"

I used to get 5 years of use out of wiper blades when I lived in Pittsburgh, PA; and this was on the original FIAT blades on my X1/9. All I did was wipe clean during its weekly wash and dress twice a year with armoural. Rain, winter salt, and steel mill particulate falluot.

I can't get 1 year out of wiper blades down here in Texas no matter what I do {unless the car sits in the garage under a cover}

Frank,
Considering the average BB gets around 500 to 1000 miles driven per year, the heat issue to the seals and wiper are meaningless... Esp. the wipers since close to none of them ever get wet, except by a garden hose... :-)

After a long drive the windshield and wipers get very hot from the heat coming out of the radiators. I wonder what that does to the life of the rubber windshield trim and rubber wipers ?

Oh yeah, and as for starting....

when I went to spin over a Boxer on the starter after and engine out big service, to get oil pressure up...the bloody thing started. It was 3 feet off the ground on the hoist and I was reaching through the window to crank it.

Get your float levels set, time and tune it correctly and they're sweeties.

I use Castrol magnatec in mine and it doesn't even puff out a huge cloud of blue smoke when you start it, like most.

I love it, but am selling it! (I live in Melbourne but it's in England)(www.theferraricentre.co.uk)

It's in the owners book guys.

Set A/C to mid/max. Shut windows. Turn heater controls to cold and air to 0. A/C comes out lower dash and centre screen.

Mine pumps 3 deg out. It's too cold if you leave it on max.

I reckon Boxers are the ultimate long haul cruiser. The most comfortable seats and driving position in any Ferrari ever built to this day, fast, and agile enough to entertain, and fast...did I say that already?

Thanks for remembering. Yes, I noticed the river of hot air flowing from the front radiators along the rain gutter and front windshield. As one moves their hand along this hot air flow, you can clearly define the streamlining of airflow.

I did not notice it re-entering the aft aspect of the window. I will pay attention to this next time out.

Thanks for the acknowledgement and observation.

David: It is due to the Fall and Winter that I decided on a BBi.HAHA

When you installed the rebuilt engine, did you also install the compressor?

When you re-do the A/C system, and possibly put in a new compressor, aren't you forced to remove the engine again?

Hank,

BB, all season car?

The 365BB has no choke mechanism for cold starting, other than the pump and pray method that I use in the colder months...It may take a couple of tries, but she'll start on a cold winter morning.

No, I did't address the inoperative AC...As I saving that project for the Winter months. Not sure if I'll go the OE route, or the Sanden compressor that alot of the 308 folks are using.

David: James' name came to my mind, but I wasn't sure......I believe you are corrct.

While rebuilding your motor, did you make the A/C operable?

Only the more reason, that when one buys a Boxer, check to make sure that the A/C works.

I recall driving in Winter......about 20 degrees.......with the windows down, and no problem.

The Boxer is definitely an ALL season car!!!!!!!

Hank,
Most interesting observation...and so true.
With the rad exiting on the bonnet, it sure does get a roasty, toaty in the BB.

A while back, I believe it was James Selevan had a very interesting thread about this (laminar flow, I believe...)

The warm breeze just make the BB more enjoyable in the cool Fall months, eh?

All of us Boxer owners know this to be a fact. ALL of the explanations blame the hot water tubes running through the center tunnel. Well, this may not be accurate!!!!!!

Recently, while driving my boxer, I noticed a warm feeling when I have my hand out the window.....about a 6 inch high area where warm air was felt. There was a thread on this where it was due to the laminar flow of air from the hot radiator, coming from the top of the hood.

I initially thought that this air just went along side the whole car. Moving my hand around, I noticed that the hot air entered the cabin just behind my head......and a LOT of it. Hence, with the windows down, hot radiator air enters the cabin directly, from both sides........interesting!

I then rolled up the windows, turned on the air, and NO problem.

Lesson learned........close the windows and use the A/C when cruising at highway speeds. Any warmth coming from the center tunnel was minimal compared to the direct flow of hot air, with the windows down. Or, at least, don't lower the windows all the way......that will limit how much hot air enters.

Maybe that is why we don't see many cars with radiator vents on top of the hood.

I just thought I would pass along this interesting observation.
