![]() ![]() My car is at about 55k, a 2017 model, I was considering doing a full coolant flush in the fall when I do my next oil change. The redblock engines are ancient things and were originally designed to run on Ethylene Glycol, no doubt about it, hence my decision to stick with good branded Ethylene Glycol from Comma, aimed at the classic market and change it every 2 years.ĮDIT: To say, this is a personal opinion and was intended to give others some insight into the decisions I've made RE antifreeze, it's not and endorsement nor a suggestion that others follow suit.I haven't been able to get a concrete answer from anyone on this, and I've read/heard both sides of the isle. Volvo have no real incentive to care about what happens to 2/7/9 series cars anymore, those days are long gone. Problem with the heater matrix- "It's and old car Sir", Weeping head gasket- "It's an old car Sir", Corroded water channels-"It's an old car Sir", and so on. These cars are 25 years old and more and waaaaaay out of warranty period. Wouldn't there be consumer uproar if the modern Volvo coolant wasn't well suited for the older cars and caused problems?. I suspect any of the modern engines that the current coolant is intended for have no 'yellow metals' involved in the cooling systems and I genuinely struggle to believe that coolant designed for their modern Ford based engineering is well suited to ancient redblock tractor engines!ģ. Ford took over Volvo in 1999, long after the last redblock engines were produced. Volvo have a personal interest in having a 'one size fits all coolant', it saves them money to offer a single backwards compatible option, avoiding the expense of offering specific support for older vehicles that they have little involvement or financial interest in anymore.Ģ. Volvo coolant used to be part number 9437650 and then was superseded by 31439720, the later part number is supposed to be suitable for all modern Volvo (Ford) stuff (CX90's etc), there's no way in the world it's a traditional blue EG coolant! I suspect that it's closer to a modern OAT but given Volvo aren't clear and the bottle doesn't make clear what it is we have no real way of knowing.Īt this point the nay-sayers will be shouting at their screens "Why would Volvo supply a coolant that wasn't right for our cars?" I'd suggest that these points are worth considering.ġ. If there is a price saving, how much is that to be botheed taking time and effort for and does the non-Volvo product sometimes cost more?ĭon't forget a recently reported experience with a non-Bosch temperature sender.įWIW it was I that reported the disappointing show from the none genuine coolant temperature sensor, however with antifreeze I take a totally different approach Why buy the Comma product, or Bluecol, or any other product, instead of buyng what Volvo themselves sell? ![]() Very good point about the "current catalogue" not including the 7/9xx models, after all, the youngest is 20 ish years old now and past even Volvos life expectancy for them.Ī Lamborgini tractor sounds like an oxymoron! That's about £7.16/L for the Volvo stuff then Bob? As opposed to about £3.40/L on Amazon for the Comma branded stuff that appears to be exactly the same! Needless to say as yet I have not received any reply to my email direct to Comma, andįor the time being I shall continue to use G48. However, I have written to Father Christmas for a Lamborghini Tractor I suspect that means their current catalogue of vehicles which I don't think will include cars as old as the 700 Series and their derivatives! I am unsure what is meant by the change being 'the recommended choice for every passenger vehicle model in its (Volvo's) catalogue'. ![]() However, you have missed adding on the P&P of £8.15 which makes it a whopping £27.65!!īut, thanks for the link to the IAAF on the subject of the change in Feb 2018 from G48 to G65 by Comma. ![]()
