Porsche 928 Engine Ruined by Coolant??

- Working our way through the fluids in the 928 and it's time to flush the coolant system. First time I have had to drain coolant directly from engine block drain plugs. Would you believe it that a shop filled the system with green coolant when they did the timing belt and radiator back in 2017. I really do hope the engine and head gaskets aren't irreparably damaged. Five years and only 5000 miles with the wrong coolant sitting in the engine sounds like a recipe for corrosion. Crossing my fingers we saved it!!!
You can't beat dealing with 928Rus. They know 928s and are always a pleasure to deal with. I get all my 1985 928 parts from them. You could have saved yourself some $ if you would have bought 2 Full strength gallons of Zerex G-05 coolant and 2 gallons of distilled water. The 928 will take all of the 4 gallons. Good luck on your project
Thank you! I will take all the luck I can get. I've had a real good experience with 928sRus so far. They have stuff others don't and it comes quick. I have found a few common parts cheaper on FCP Euro and have had good experiences with them too. I have been using FCP Euro over the last few years for our BMWs (E92 335is I used to have and the E30 325is we have now).
No it was a wonderful design the Porsche 928 was over built and was years in development from 1971 through 1978 when it launched. It was designed by German engineers with you do it like I say (typical German way) or it’s not the right way. Special fluids for a special car. It was created with such high tolerances that the engine doesn’t wear using the right fluids that’s why when you change the oil and other fluids they are never as dirty as you think it should be. Not a mere coincidence 😉
I'm hoping over built means I will be able to enjoy it for many more thousands of miles before any major engine maintenance. It's at 117K right now.
They're tanks, my 84 has 159k on it and i drive it regularly. Like any good car, maintain it and it'll last a long time. 👍👍👊👊🤘🤘
@@MrAmk3rd My 928 sat in the grass for 15 years and has 211K. Engine runs like clock work. The car sat because some idiot put the wrong relay for the auto transmission kick down, and that idiot was a classic Porsche dealer mechanic. Before the year 2000, German cars are extremely well built. Afterwards though there's a lot of plastic in the engine bay and rubber seals tend to fail. Mercedes has a period where the balance shaft would fail due to inferior steel. BMW's went through bolts shearing on Vanos sprockets due to inferior steel. They literally don't build them like this anymore.
You need to put a oil cooler bypass and change that radiator asap they designed it to have oil pockets inside your radiator that rot out and fail causing oil to get rad ain’t freeze in the oil before it happens to you…. Which it will even more because you had the wrong fluid in the radiator those oil pockets will fail shortly which will destroy the motor. Install a outside the radiator oil cooler once you look into this issue you’ll thank me tremendously because it’s bound to happen to your radiator only a short matter of time before it does . Look into it , or ask a good mechanic who knows Porsche 928s you’ll see im 100% right and I’m believe it or not saving you the motor thats in that car very bad design by Porsche when they built the 928 to place weak pockets inside the radiator to cool oil .
I’d change it asap to be safe because after years of it failing on so many other cars you are super lucky to last this long without it leaking and having antifreeze mixed in your oil destroying your motor . You’ll thank me latter for this information all I can say is address it as fast as possible . Real bad design by Porsche ,
Your welcome ,
glad I can pass along side me real solid information on to you and help save your motor and car .
Don’t believe me…. Look into this you’ll see it’s a major problem with these radiators , install that bypass you’ll be fine then and never have to worry about it ever .
Thank you. I will definitely look into it and see what options I can find to avoid this problem.
its not the color of the coolant its what type of coolant. its comes in all colors you need the right type of coolant. the coolant y pipe is metal the water pump rotor is cast iron. every thing else is aluminium. engine heads radiator and heater core. just dont mix coolants. unless they are the same type. not sure what you got or dont have then top up with demineralized water.
That makes me feel a little bit better about the green coolant we found in the system. Haven't run into any issues yet. Just keep our fingers crossed it was the right type. We flushed it out and put in the right coolant, so we know what we got now.
No, it was ruined by poor design!
I'm not an engineer, so I won't comment on the design. My issue is that a professional shop put the wrong type of coolant in the car and likely caused accelerated corrosion around the head gasket.
@@C3KPaddock that probably didn’t help but the 928 is famous for head gasket failures
@@JeepCherokeeful what year 928 is famous for head gasket issues and at what mileage?
