Intake manifold antifreeze leak

  • GMC
My mechanic replaced the exhaust gaskets on my Chevy Tahoe. At same tiime a "board" (?) Was replaced to resolve a blinker / tail light failure problem.

One week later my auto broke down. The same mechanic then replaced the alternator. He also questioned me about seeing any antifreeze under the vehicle and advised that I needed a new intake manifold gasket due to an antifreeze leak.
I had just observed signs of an antifreeze leak that started within days after the exhaust gaskets were replaced.

My question. In the process of replacing exhaust gaskets could the manifold have been disturbed to the extent that the antifreeze leak started? Any possible connection with the "board" beiing replaced and my altenator going out? Just seems strange that a second set of repairs would follow so closely to the first set.
Do you
have the same problem?

Depends on which exhaust gaskets were replaced. Did they go all the way back to the exhaust manifold or start somewhere near the cataylic converter. If they only replaced near the cat then your intake manifold would have been nowhere near the gaskets replaced. If they replaced up towards the exhaust manifold then they would have been close but would not have even had to tamper with the intake manifold.

Regarding the "board" for the brake light.I have no idea what this is.
