i have a 2004 2.7 liter toyota tacoma with 135000 miles. the head cracked and was leaking coolant into the #2 cylinder. it wasn’t catastrophic and was still running with just a stumbling idle at start up when cold.
that said i took it apart, found the crack and i am in the process of replacing the head at home, my mechanic did all the diagnosis work.
i don’t remember overheating or when the head could have cracked.
question is…what should i check or replace while the head is off so that i don’t crack my new head??
there were never puddles of coolant under the truck.
any input is great.
i just don’t want to replace my head and crack a new one.
