My neighbor has an 06 GMC Sierra with the 4.3 V6. The thermostat is stuck open and her engine runs cold,of course. She went to the dealership and bought an AC Delco thermostat. I'll be putting it in for her. My question,will enough coolant leak out that I'll need to get some to replenish what leaks out,or will it be a minuscule amount not to worry about? And I'm guessing it's GM Dexcool,right?
Thanks in advance!
