I have been working my way through the 60K service list on my 2004 SE with 58,000 miles and hit a snag. It took me an hour to find (what I think are) the engine block drain plugs for a coolant flush. I will include photos, but have I found the correct plugs how the heck do you remove those things? Is there some special trick or tool I don't know about? If I remember correctly, the plugs I found were both 10mm. One is right above the front differential and impossible to get to thanks to a wiring bundle, and the other is between the wheel-well and exhaust pipe. Is it even totally necessary to remove them or will the radiator hose/ water flush suffice? Also, per DiscoMike's recommendation I purchased DexCool. Is that in the trucks best interests? Thanks for the help, I don't know where I would be without the forum! Dont even get me started on the Viscous Fan removal!!!

 

Yes those are them. Don't bother removing them just pull the bottom radiator hose.

 

And don't use DEX-cool! Use any other brand aluminum safe coolant--dexcool turns VERY acidic and corrosive enough to eat through all sorts of Rover goodness.

 

I flushed my Dex-cool and replaced it at 80,000 miles. I have been fixing problems that were associated with it ever since. It has corroded my thermostat housing and numerous gaskets. I suggest replacing it with peak 50/50 or anything that you dont have to service as often. Check this out: http://sancarlosradiator.com/dex-cool.htm

 

Thanks for getting back to me. I will go with the bottom radiator hose method. If I change the DexCool more frequently would it be ok?

 

Are there any additional steps necessary to convert to green coolant? Flush with water a few times?
