They replaced all of them,upper and lower. Had `em replace the thermostat too while they were in there. I did another post yesterday about Dexcool and after reading that website I think I`m gonna flush it out again and go with prestone green.

 

that would be a good idea...When I had mine done we just put in a universal coolant, and it works fine. I have 195* tstat in there now, I might lower that when it gets warmer...185* probably...We'll see...it's not like it is expensive to do. lol. It was like $90 for the uppers and $40 for the lowers. (I think, receipts aren't with me right now.) Then the water pump was $38, tstat was $8 w/the gasket.
