    Coolant pipe stint

    Inquiring about this stint that seals the coolant pipe seal which wears over 1100k which leaks from weep hole. 1) Has this worked or failed for any users? 2) Should the conditioner be poured into my cooling system to prevent further leaks to hoses?

    Be more specific about what component your asking a question about. What type of BMW. Where is it located. Provide a picture if you can.

    Its a 645ci and the location of the stint is sealed to the existing coolant transfer pipe with sealant after the water pump is removed. The product is bimmer fix.

    Have not used that specific company's product. Using a conditioner won't hurt anything. Do a google search for. "n62 coolant pipe" you'll see other versions of coolant pipe repair kits. I've seen the 2 piece pipe used successfully several times. Don't recall which brand.

    Before stint is installed they ask to place a generous amount of sealant around the stint and placed at the entrance of the transfer pipe and to dry for 24hrs. will this black sealant circulate through my engine and harm anything?

    Best bet is to fix the leak and not cause a problem with fix a can ... If it can clog a big leak... What does it do to the heater core, radistor?

    Pouring the conditioner into the radiator hose can cause additional issues as you have specified. What about the 2 inch stint though the transfer pipe with the sealant to basically stops that seal from wearing and causing that weep hole leak again
    As they do fail over time. I think im going to try the expandable pipe just more work. Thanks for the caring responses.
