Normally if the handle moves the butterfly is moving also. You can check it by running the engine and moving the handle open and closed. You'll be able to feel and hear the exhaust change.John Pizzi - Squarebirds Administrator

Heat riser
Again, great information. I'll post what I find after the weekend. Much thanks to all.Comment

Heat riser checked out ok
My new Bird has been in the Transmission shop this week getting leaks fixed, so I thought I would go by and see what I could see regarding the heat riser. The Tranny was out, and a piece of bad exhaust piping had been removed from the bottom flange of the heat riser back to about the middle of the car. Anyway, I had a perfect view of the vane from the bottom side. It's frozen in the open position. So, one piece of the overheating problem eliminated.Comment

If it's going to be stuck, you want it stuck open. So, just leave it open all the time.Member, Sons of the American Revolution

Radiator - Recore Radiator vs Replacement
Does anyone have an idea which costs more or which way is the best way to go? Thanks.Comment
-
Either way is acceptable, but the trans oil cooler is in one tank so I personally would want a complete assembly. But you have to be careful here as most replacements are now poor quality off-shore. If there is a not a specific BIRD vendor offering a direct OEM replacement, I would research MODINE.Comment

Original radiators are made of copper and brass. They transfer heat MUCH easier than aluminum and they are easy to recore. Recoring aluminum requires TIG skills.
If you buy a new one, beware... more rows of core obstructs air flow which requires a stronger fan to push air through. - DaveMember, Sons of the American Revolution

bon ami/ commet
[QUOTE i hosed my block and had the rad cleaned , next i poured in
water and half can of bon ami scouring powder. drove it one day then dumped the lower hose , (put in a freash wire ) so it dont colapse.
also with the weight of our fords . i bent up some 2 1/4 " head and
exhaust pipes. Nothing says get rid of heat like one size bigger pipe.
two and one half " is overkill. most everything else was covered
im certain.Comment

ayrwoof, I understand your intent, but keep scouring powders far away from your cooling system (yes, even Bon Ami). They are abrasive to the water pump seals and they really don't do much good on lime deposits.
Tell us what came out of your block when using the hose. That had to be a tremendous help if you took the core plugs out.
Antifreeze contains a rubber lubricant and phosphoric acid in a very mild concentration. That's also the active ingredient in CLR (calcium, lime, rust). I'm not promoting CLR, but you really need the phosphoric acid to disolve lime buildup. I have found phosphoric acid in different products, available at some of the big stores. Crud Cutter has a product called, Must for Rust. It's about $8 per quart, but it works real well on radiators and heater cores without affecting the solder or brass. Some of the alloy wheel cleaners also contain phosphoric acid. Try to beat that price, too.
So, flush your system as soon as possible to get rid of the abrasive. Most acids work much faster when heated. I remove the radiator and use a cheap drill motor pump to circulate the acid in a tub, (heated with a Coleman camp stove). In the first half hour, you will see LOADS of crap in the tub that came out of your rad. Reverse the flow, and cycle it every two hours or so.
For the heater core, I usually keep it in place and just extend the two hoses with the tub and pump setup. - DaveMember, Sons of the American Revolution
