Installing new stainless steel transmission lines and they are very close to my headers (within 1/16"). My question is if that will cause problems with my brake system? Or boil the fluid? This 70 GS 455 has drum brakes. Everything seems to be very close in that area. Is this normal with a header setup?o No:
Not sure of your queation? I used Poston Headers and ordered SS Transmission lines from OPG? Is their something I don't know or should have before ordering?
Ive always had to remove the stock transmission lines whenever I installed headers. They usually dont fit anymore once the headers are bolted in place Thats why I was asking.
"Installing new stainless steel transmission lines and they are very close to my headers (within 1/16"). My question is if that will cause problems with my brake system? Or boil the fluid?" How is the tranny lines gonna effect the brakes??? hehehe so I assue both lines are real close to them, ehy? Move them. When it comes to tranny [sometimes brake] lines stainless steel braided hose is the best choice as its easy to route where ever with out needing to bend up custom tranny or brake lines. Also works well. Usually the brake lines are only stainless covered hose where you need flex or to replace a stock exposed rubber hose. You can spend the money on fancy AN fittings and such if you got loot or use regular brass hose barbs and clamps. Tranny coolant lines do not run wild high pressures like inside, hose barb fitting and clamps hold just fine, just like they do for the cooling system.
O.K. you got me, I'm an idiot. i meant will itaffect the transmision fluid, but this is probly a stupid qestion also?
As long as they're not touching, the transfer of heat wont be as bad. Are you talking about the brake line where it makes that "U" bend down into the brake hose? They are 3/16" lines. They bend pretty easy. Can you tweak the line a little to get it further away? Same with the transmission lines, see if you can tweak them a little to gain some clearance. When I first installed headers on my 71, I bent up custom steel lines and re routed them away from the headers. With the M/T's, there was no way to re use the stockers.
I can't say for sure. It bugged me for years that factory my stock tranny lines nearly touched the Y pipe, I shoved a pop can between them and it was in there for years to seprate them some and act as a heat sink. When I put in my new tranny I used stainless braided hose and got them routed proper away from the exhaust. Myself I would not let anything like that be within an inch of touching but is that proper science? I dunno, might make no difference what so ever. For peace of mind I don't let things close to the exhaust. Heat, melt, rub worn, possiable fire, bad.
Dean, Another option would be to wrap the lines with some kind of insulating wrap. If you look in the Jegs catalog under exhaust, there are lots of wraps to choose from.
That's what I would do. If you can twek and eighth of an inch between them and wrap some heat barrier around the line in that area you will be fine. I used header wrap but I'm also going to put some heat wrap around the brake and tranny lines where they come close.
the problems your having dean is the reason i run ported exhaust manifolds. with the right exhaust it can sound almost as good as headers.
Thanks everyone for your input. Larry, the 70 GS 455 I'm restoring the same color as yours, I used to have one the same color when I was younger. Like the look of the Brown/ Black top. What color is your interior? Mine is saddle, not sure how that will look. Hope to get her painted this summer. Then maybe concentrate on the X.
I ran braided stainless lines through the frame with black AN fittings. Probably gonna change my steering lines over to this as I like the look and have extra hose.
