Thin Lizzy 38 Report post Posted July 6, 2019 Hi All, was hoping someone could please help, there's a leak from the front radiator as shown below. I'm no mechanic but should I just tighten up the bolt closest to the radiator or is it time for a new radiator? Thanks for any help you can give. Mark.

mustangstofear 608 Report post Posted July 6, 2019 That looks more like anti freeze than tranny fluid. Radiator is probably shot. 1 Thin Lizzy reacted to this Quote Share this post Link to post Share on other sites
barnett468 418 Report post Posted July 6, 2019 you need to determine exactly where the rad is leaking from first. There are no nuts or bolts to tighten that would fix a rad leak but if it is tranny oil then it can be fixed.. Quote Share this post Link to post Share on other sites

Thin Lizzy 38 Report post Posted July 7, 2019 Thanks for your help. Could there be a leak around the tranny line where it meets the radiator. Can’t see leaks from anywhere else. I’ve bought some Holts Radweld, not sure if it’s detrimental to the engine. Need it to plug the hole till I can get it to the Mechanic 20 miles away.

1969_Mach1 335 Report post Posted July 7, 2019 Like Barnett mentioned, first determine where the leak is coming from. Clean up that mess, run the motor, drive the car a few miles and double check. I'd also check the trans fluid just to be certain coolant is not getting into the trans fluid from a leaking trans cooler inside the radiator. These work good for stopping minor coolant leaks and do not clog cooling systems. They will make the coolant look a little muddy in color. 1 Thin Lizzy reacted to this Quote Share this post Link to post Share on other sites
mustangstofear 608 Report post Posted July 7, 2019 Your best bet would be just remove the radiator and take it to him. Quote Share this post Link to post Share on other sites
