    Can you repair a cracked 5/8" aluminum tube?

    OK I have an old 1996 S420 vintage large Mercedes and hit a curb at 40 mph with no damage to the exterior but I cracked the suction line (small crack 1" long) and it will cost $400 to replace the line.

    Need to get the ac leak fixed. Can the crack be welded shut and how.

    Any aces out there good with repairing aluminum tubes?

    Appreciate all the advice I can get here. thank you very much

    Yep... you tube videos.... many products out there.....

    One thing that concerns me is that it is a crack..... Ive brazed up cracks on lines before and had them continue to crack under the braze material..... think you might have to get something like a very small orifice drill bit and drill out the ends of the crack to keep it from growing.

    or.... dont drill them completely thru...... use an orifice bit in a brass holder or something and then.... take a needle or something small and poke the hole the rest of the way thru so you dont get any metal dropping into the pipe...... or take it off .... make the repair.... blow the pipe out and reinstall....

    Celebrate with a chocolate...... or what you southern guys call.... a choclate.... frosty and cup of warm coffee......

    I would have fiqured you for a Ford man..... Glenn

    Yeah corny that's all I buy in trucks and cars except for this vintage bullet proof big black S420 I got at a good deal from my brother in law who has a used car and mechanic shop business.

    That way I can drive through the hood with a rebel flag on the front of the car without getting shot. It weights 5,500 lbs and is a tank using high test only gas. LOL. Thank you very much
