Hello,
I'm wanting to change the fluids in my truck. I'm wanting thicker oil protection, not thin mileage oil . I have a Chilton and a 1/2 ton 2004 Silverado 4.3 5 speed .
The clutch looks straight forward. There's a bleeder and you get help and do it like brakes. I'm hoping its as easy as it sounds . It will bleed wont it. But DOT 3 looks good to me.
And the transmission. There's a NV 3500 and 4500 and a ZF S6-650 .All have different fluids. Do I have the NV 3500 I don't recognize the fluid specs. Cant I just change it to synthetic. gear lube. like 80-90 GL5. There's a synchromesh, A Syn torq , And trans synd. Fluid.
And the radiator. Can I switch back to green anti freeze. If I flush it out with the water hose while its running. Until its clean.
And I want to put 15-40 oil in the engine for the summer. I don't see an issue with that.
Thanks, Diesel.
