Transmission Fluid Dipstick & New Heat Exchanger

I would try using a 6pt combination or box wrench on it. Put the wrench on, hold the hex end down on the dipstick hex head with your palm and then hit the other end of the wrench sharply with a brass mallet in the direction of loosening the piece. Often jarring it like this will break it loose. Be careful if you resort to the heat wrench. RT

You know, I did not try pulling the hx backwards, cant remember why, maybe bracket blocking. But if that is all it takes to allow the dipstick to come out I guess its easier than relocating hx or reengineering the dipstick. I know the cap is a lefty loosen thang and comes off with a small adjustable wrench. Thanks again for that tip!

Thanks

Thanks all for the great suggestions. I will eat my Wheaties and give it a go tomorrow evening or Thursday evening, and let you know. Heat gun, what a great idea. I would be nervous with the torch around the fuel and oil.
I am lucky to have great access via a cockpit sole hatch, right into the back of the engine and tranny.
David, I have enjoyed pictures of Emerald, and hope to have some of my own to share soon. Brought this darling back from the grave, nearly.

Dont use an adjustable wrench unless you want to trash your fitting and your hands. There's a reason they call those things knuckle busters. IIRC its 11/16" If you cant get leverage with a box end wrench try moving the HX back and going down with a socket and an extension. Maybe a swivel extension or swivel socket but be careful that the socket sits square with the bolt. Heat gun may help but be carefull. It will lift the paint on your engine almost as fast as a torch. The heat from a heatgun is also not as easy to direct and control as a torch. I would opt for a small torch myself but I have used them a lot and are compfortable with them in engine rooms under the right conditions. PB blaster is a good penetrant to try as well.
