Title: Spark-plug #4 coolant leak Question
Post by: TSaL on July 10, 2013, 04:11:37 pm

Looking for direction. I had my truck looked at an auto repair business. The want to replace my cylinder head because of a leaky spark-plug #4. As you can see from pictures it does look like coolant has or is leaking. I don't understand why they would replace the head if its not leaking by the spark-plug. Please forgive my ignorance.

I'm thinking head gasket.

Thanks for your response. I think this weekend we will start pulling it apart. I will try and take some pictures while we do it.
