What to do if coolant leak from intake manifold?

To make sure your intake gasket replacement doesn’t come back with a coolant leak in the near or long term… there’s another very important consideration to keep in mind and it’s that you need to torque the intake manifold bolts with a torque wrench.

What are the symptoms of a bad intake manifold gasket?

Coolant leaks Another symptom of a faulty intake manifold gasket is coolant leaks. Some intake manifold gaskets also seal engine coolant, and if the gasket wears out it may lead to a coolant leak. This may produce a distinct coolant smell, along with steam, and drips or puddles of coolant underneath the vehicle.

What’s the best way to seal an intake gasket?

Step 1: Apply sealant. Applying sealant is a judgement call; it’s not always required. Your workshop manual can help with this. In some cases it may only be recommended around the coolant or oil passages. If the gasket has rubber O rings, gasket sealer won’t really be helpful.

Why is coolant coming out of the intake?

This expansion and contraction is due to the engine starting and heating up and then cooling down when turned off. Over time and thousands of miles, this action of expansion and contraction (of the cylinder head and intake manifold), plus the rushing/moving coolant starts to eat away and/or tear the intake gaskets at their coolant ports.
