George, sorry for the delay in replying. I had to take some photos of the louvers
-see pictures on the Picasa link at the bottom of this message. The guy who
built the plane and fitted the louvers operated them by a bicycle type bowden
tension cable that puuled them open against an automatic return spring. It worked
well but he used a rotating knob on a screw-thread to pull the cable and
this took minutes to wind all the way in. A 4 stage lever (like the original
Pulsar flap lever but much smaller would have been better.
I replaced the cable with a small geared electric motor driving a worn and worm-wheel
and micro switched to limit the travel and give feedback when fully open
and shut. It takes about 10 seconds to move from open to shut and works well.
But is a bit OTT unless you want to operate the louvers automatically from a
water temperature sensor (in my "to do" list).
The port radiator does not have adjustable flaps but is sometimes masked according
to ambient temperature - fully masked below freezing, fully unmasked above
28 degs C and part masked anywhere in between.
Although they work well the louvers would be difficult to make. A simpler arrangement
would be to make a "roller door" type blind operating sideways and with
the slats constructed from aluminium piano hinges. This is also in my "to do"
list for the port radiator.
I've also included a few general pictures of the engine showing the expansion bottle
and the oil injection tank.
Let me know if you need any more info, the link to photos (you might need to paste
it into your browser) is:

I had a Volvo in the '50's it had a roller blind that pulled up infront of
the radiator and sprung loaded to retract it.

Bob, thanks for the response. That is really a sophisticated set up. I gues
s once you get it to operate automatically from the water temp it will be p
retty slick. The roller door is a good alternative and less complex. I was
also thinking of installing an automotive heater control valve to adjust th
e water flow through the radiators using a push/pull cable. =0A-=0AThanks

Hello 582 operators
It may be is easier to shut of the coolant line instead of the air flowin
g thru the radiator.
I installed a valve in one of the 5/8 coolant lines between the radiators
. It is operated via push/pull cable.
Works great as I can ramp down the coolant flow to the rt radiator. The cab
in heater works great as it routes the heated air from the still operating
left radiator.
Real simple to install too.........Clark

Think back two years ago when I broke down in Searcy, AR with a busted oil
cooler. Well, my cooler has again developed a leak but at least I'm at home.
I pulled the cowls today in preparation for an oil change. I pulled the
plane outside and ran the oil up to a nice 175 degrees, then pulled her back
inside the shade of the hangar. After pulling the oil tank plug, I noticed a
couple drops of fresh oil on the ground forward of where I was working and
traced it to the forward fitting of the cooler. There was no sign of oil on
the lower cowl so the failure happened during the engine run today. The
nature of the failure is the same as last time and that perplexes me. I had
added a solid hose support about 6" behind the failed fitting which
eliminated any ability for the hose to move. Previously, it was able to move
over it's ~20" length which allowed transmission of stresses to the oil
cooler. The failure is radially about 1/2" around the forward side of the
hex fitting where it joins the cooler.
I'll try to have it welded by someone who knows what they're doing but in
the meantime, I'm on the search for an Earl's 61002. As I found out two
years ago, they no longer make that size and I have not found an exact
replacement after searching a couple of hours this afternoon.
Does anyone have an Earl's 61002 you would part with? I'm sure hoping to get
this fixed and avoid having to cancel plans to attend the Lawrence
festivities on Thursday.
