I have a 2005 Sierra 1500. 5.3l Vortex. The coolant is milky like a strawberry milkshake. Oil looks good, trans fluid looks good. It keeps running hot and I don’t know what’s causing it.  I don’t know what caused the coolant to become milky.  Any ideas?  I appreciate any assistance. I’m no mechanic.

Needs a radiator if the coolant is like a strawberry milkshake. That means transmission fluid is getting into the coolant.

 

Get that fixed before damage is done to the transmission as well.
