Reader Question: Hi,
The other day I was driving my 1987 Dodge Dakota and all of a sudden smoke came out from under the hood. Then I popped the hood and realized it was antifreeze going on the exhaust manifold and it looks like its coming from the water pump or the head gasket.
I was wondering if I have a blown head gasket or a bad water pump. How do I know for sure what it is?
You need to get a cooling system pressure test done FIRST if you cannot easily see the external leak.
You probably just have a hole in a radiator hose, water pump leak, or some other external coolant leak…and probably not a head gasket or some other internal engine damage.
