| coolant and tranny fluid.
I'm going home this saturday to flush my coolant and change the tranny fluid.
On the car it says to use the GM coolant additive... is that nesecary cus of the alumimun heads? Or is GM jsut trying to sell me an expensive bottle of stuff i dont need?
Tranny fluid: anything i should look for when doing this? Any special steps? Should i check anyhting on the valve body if i have the pan off? |
