    Funny. I think you know what I meant.

    Can fresh coolant dissolve old mineral deposits?

    I did search, extensively, nothing I found addressed my specific problem. Why are you so heavily biased against Prestone? When using the properly spec'd coolant, with proper maintenance intervals, I have found Prestone to be perfectly fine. I think in this regard, proper maintenance is far more...

    Can fresh coolant dissolve old mineral deposits?

    What would be wrong with the heater box? My original post actually says that the passenger vents get "great heat". Since I've done the flushes the drivers floor vent has gone from virtually no heat to tremendous heat. The extreme left (drivers side) dash vent is the only location that isn't...

    Thanks, but I'm not looking for guesses.

    Can fresh coolant dissolve old mineral deposits?

    My 2005 Jaguar XJ-8 Vanden Plas seems to have been maintained extremely well by it's former owner, with exception of it's cooling system. It produces great heat on the front passenger's side (80-90˚C), but much less heat on the drivers side (something like 30˚C- 40˚C after I bought it). I...

    Paging the Oil Filter Experts!

    Theoretically, yes. Have you ever cut open a Bentley filter to verify your theory?

    Paging the Oil Filter Experts!

    Maybe. I'm just relaying what I see with my own eyes. Are you telling me not to trust my eyes? What empirical evidence do you have to validate your claim?

    Paging the Oil Filter Experts!

    I'm curious about this comment. Are you literally saying Mann is no longer good? I'm not picking a fight, just looking for info. FWIW, the Mann filters I've recently cut open are really nice. They were for VW and Jaguar. I think I've come to the conclusion that filter quality often has much to...

    Confusing Porsche Oil Intervals

    I don't worry about resale value, not because I'm rich, but because I drive my cars until there is nothing left to drive. During 39 years of car ownership (I actually owned two cars before I had a driver's license, 16 in total and I still have the first one) I have never sold a car.

    How long do you keep a car or truck?

    As you can tell by my signature, I like'm old. My objective is to drive them until parts become unavailable. The cheapest, new, decent car in Canada (Civic, Corolla, etc) is about $500.00/month over 5 years. That assuming you don't have to pay interest on financing. $500.00/month can pay for...

    Prestone Total Cooling System Cleaner

    I have never had to flush any of my cars, but I've always drained and filled the systems every two or three years. With this method my cars basically get a complete coolant replacement every 5-6 years. The new-to-me Jag will need the rad, engine and heater core flushed separately. Lots of...

    Confusing Porsche Oil Intervals

    On two different occasions I had the $250.00 belly pan come off of my Passat, after dealer oil changes. The first time was at 110 km/hr. and the rear wheels drove over the pan destroying it. I had to fight with the dealer to have them replace it out of their pockets. The second time was much...

    Confusing Porsche Oil Intervals

    Says the man who's never owned a Porsche. Arrogant? Do you understand the concept of projection? https://www.psychologytoday.com/us/basics/projection What makes you think you are justified in being so dogmatic? Especially, when you have zero firsthand experience? :rolleyes:

    Confusing Porsche Oil Intervals

    Thanks for the clarification. Despite my error, I still think if the car is maintained properly, with corroborating documentation, the resale value will be unaffected. For what it is worth, I had my new VW Passat serviced at a local VW/Porsche dealer during it's entire warranty period. Without...

    Confusing Porsche Oil Intervals

    The OP's car is a 2018... meaning out of warranty. What matters is good, properly done, well documented service. Not fancy book stamps. Spend your money however you want. I'll choose to spend my money on proper service, not expensive stamps. Cheers

    Confusing Porsche Oil Intervals

    So true. I talk to my independent mechanics, both before and after the work. I'm positive that our respectful rapport results in more attention to detail and better repair outcomes. I can't remember one time, in the last 25 years that I was even allowed to talk to a dealer tech.

    If you choose to do the work yourself, you can consider doing what I do. Photograph the odometer and the items used for the service. That way you have date stamped proof that the work was done and the lack of a book stamp will be irrelevant.

    Prestone Total Cooling System Cleaner

    My Jaguar only delivers full heat to the passenger's side. Although the former owner felt like he maintained the car perfectly, I think the cooling system might have only received a drain and fill once in 18 years... and I don't know when that was. I have used the flush kits before, and I can't...
