Anyone know how to test coolant for exhaust contamination?

[christutecky]

hey, I read the "Blown Head Gasket Symptoms", and it got me semi worried. The other day, my rad drain plug must have gotten hit by a rock or somthing, cause it snapped off, i replaced it and the fluid....and for the next couple of drives, my Rad light came on, and I was low on fluid....now im pretty sure this was because the system needed to refill its self from the resivoir, so i have filled it back up and the light has been off since..BUT..I do have a stutter when starting..it it hard to start all the time...cold or warm....AND the other day when the hood was up and the car was running, I notcied some smoke coming from my engine....now i hope it was just something i got on the engine when i was toppin off the oil...but...:-S.....anyways..I want to check my coolant for exhaust contamination..to make SURE I dont have the BHG.......how do u do this?


Thanks for your time
