I have a 97 mustang GT that has a coolant leak at the back right side of the manifold. My coolant level in my radiator becomes low when it leaks. Can I use Bar's stop leak to stop this problem?

 

Yes, that wasn't corrected till 2002. They updated it with a metal coolant passage on the
front of the intake manifold, to prevent future issues. There is no factory authorized repair
for the intake manifold, and replacement is required to correct the engine coolant leak.

OR, you can sand it rough, and apply some JB Water Weld, and let it fully cure. I did that
with a 2006 Jeep Liberty when the LH side tank of the radiator spring a pisser leak. I sanded
it, and applied JB Waterweld, and it held for the following 6 months I kept it.






Yours just cracked somewhere else...
