Hello, I have a 91 Hatch back with d15b1 motor.....Antifreeze is milk color in the radiator??? Any suggestions? Bad head gasket? What kind of coolant should i use just straight antifreeze and any suggestions on changing it would help. Thanks

 

yeah that is telltale of a blown head gasket. you need to swap it out if you want the engine to last.

 

Do a compression test.

 

heres a pic of my antifreeze

 

yeah its a very big sign of the head gasket being blown

you should use the proper mix of anti freeze depending on where you live

 

Looks like it.

Mmm... Mocha LOL.
