Prestone Platinum Coolant
« on: 26 September 2022, 23:15:47 »

Hmm.. First I guess I should ask if they sell this stuff in the UK?

I am about to do a full system flush and plan to replace the old Dex Cool red stuff with Prestoine Platinum.

Anyone here use this in their Omegas?

Not sure I've seen that in the UK, only Prestone products I've seen here are budget end car shampoos.

As long as it meets the spec of what the glovebox user handbook says (and its important that it does), I put in whatever is cheapest/convenient.

What are you expecting it to better than any other coolant that meets the engine desgner's specification?

Pretty sure ECP also sell it. Not sure about the spec though.

According to the literature it is the best they make and will last 15 years or 350000 miles.

An Omega won't retain coolant for 35,000 miles - which is almost the timing belt interval - let alone 350,000.


Which makes the manufacturer's marketing wank irrelevant even if you beleive it.

Point being that for the same price as Dex Cool you get what is allegedly a better product. With my mileage being well under 5,000 per year it will last several years with no worries.

In any event, it's my choice for the upcoming flush and recharge in the next week or so before the season kicks in up here in the mountains.

Rubbish.....
I've had a couple of V6 Omegas with full Vauxhall service history, but with no mention of coolant flushes/ changes in over 8 years. Not ideal, and obviously something the previous owner didn't feel necessary or didn't want doing, but the cam belt change and coolant was one of the first jobs I attended to.
But to suggest that the Omega engine won't 'retain' coolant for 35,000 miles or more is claptrap.

But...another new OOFer treated with condescending and critical comments which I think is totally unreasonable. Surely having advice from experienced owners is what he wanted, but there's a way and a manner in which to give it.

It should be noted that the weak spot in the Omega cooling system has nothing to do with the coolant.

The HBV should be treated as a service item. Even genuine ones have been known to fail in short order, ie within two years, and when* it fails, it will dump the coolant.

The problem is not knowing what combination of neglect has previously been used to top up the system following a slow leak (reseevoir/cap) or a catastrophic one (HBV).

The moment incorrect fluids such as tap or mineral water or incompatible coolant are used, the system degrades from the inside out.

It isn't possible for one coolant to meet every manufacturers specifications. And given that coolant changes are a service item, I would suggest sticking with Dexcool as described by GM.

*If isn't an appropriate word in this case as at some point the HBV WILL fail.
