I have a 2008 Saturn Vue XE 2.4 eco-tech engine that have a hairline gasket crack, & my question is, can I convert my coolant from OAT Dexcool to G-05 HOAT with thoroughly deep flush that I know will be maditory. Also if I should put a blue devil head gasket sealant as well to seal the leak. I recently change the water pump while doing so I smelled burnt Dextcool as I was retrieving the drain plug on the water pump as I was draining due to combustion air burning the DexCool but I have not notice any indication of leak or water indications on the oil nor on spark plugs or the chambers, with the conclusion of my question, would it be wise for me to replace my DexCool OAT coolant to G-05 HOAT or just stick with the Original manufactured OAT DexCoolant ?

 

Well,

Based on this tidbit I found on the net from someone directly asking Prestone"

Hmm.. update from Prestone:



Thanks again for your contact. Silicates have long been used as an ingredient in
the corrosion inhibition package for
automotive antifreezes. We continue to use them in some of our formulas.
Silicates, however, are not viewed as a long
lasting inhibitor so other ones are necessary for the extended change intervals
that many of the car manufacturers are
recommending. Antifreezes that are silicate free are not considered inferior to
ones that contain silicates. For
instance, Asian manufacturers have recommended and filled their vehicles with
silicate free coolants for many years. If
the absence of silicates in antifreeze created a corrosion protection problem,
we would expect to see similar concerns
with Asian vehicles as well. This, however, is not the case.

In summary, there are both good silicate and silicate free formulas available on
the market.

We hope this has been helpful.

Wow ---that's a decisive vote for ......?

Unclear what your motivation is for switching. Me, I put in what the OEM recommends unless I have determined via my own research that it is bad

 

Stay away from the Blue Devil. It's crap. I have a buddy who's a professional mechanic,ASE Certified, out in Sacramento. He swears by this product but says if you DON'T follow the directions EXACTLY, that you'll need another engine. He uses this on every used car he purchases. https://www.moroso.com/ceramic-engine-seal35500/ I trust this guy 100% because he's never steered me wrong on any mechanical issue that I've had to call him with. But, the ultimate choice is yours.

 

Thanx for that information I was debating at firs but I just went ahead on using the G-05 without the blue devil sealant, I was having the doubtful feeling on the blue devil but I’ll definitely check out the link you shared.
thank you

 

I was told by a friend of mine that is a Mechanic by giving his opinion that G-05 HOAT would do the same as DexCool since Honda manufactured the engine for the Vue which gives G-05 the advantage due to DexCool breaking down the plastic gasket that would lead to crack. I was more towards looking for a better solution that would benefit my vehicle in the long run but yes I see your opinion due to facts on your research that you have provided me with.
Thank you

 

I think you will find that Honda only provided the v-6 for a few years, all the 4 cylinders were GM engines.

 

You’re right, Honda did make V6 for few years
