Hi guys,

After doing the engine head 6 months ago, I flushed the cooling system with "something I don't remember what brand" radiator flush but I'm still seeing a little oil in the reservoir. Not much and I'm not even sure if it's just leftovers in the reservoir.

I'm leaning more on doing another flush since I just remembered to check today the brand I'm currently using. Guess what, I've been using GM approved Dexcool.

So for the short of the long, I'll do another flush this weekend. I'm planning to buy Zerex G-05 but would like get your recommendation on what to use for cleaning. Should I use the Zerex Super Cleaner or Super Flusher? Also, would engine degreaser help clean out my reservoir?

Thanks in advance.

Hi guys,

I'm trying to take off the coolant reservoir for flushing/cleaning but it seems to have a bolt or pin holding it down from the bottom. Head of pin goes all the way through the front passenger side wheel well. Has anybody had experience taking this off? How?

Thanks in advance.

Usually on the bottom of the resevoir there is a hard plastic shaft that has a rubber ring that 'pops' in the hole in the wheel well. The only damage I have heard anyone suffering is applying sideways pressure and cracking or breaking it off. Easing it out with different kinds of upward pressure works. Slow, steady patient force works with just about everything.
