It never ceases to amaze me how so many people think they know so much more and are better educated than car manufacturers.
If you intend to keep the car for a long time, use the products the makers, designers and engineers of the vehicle recommend and do not listen to "internet engineers". Using coolant that is designed for use in pig iron castings (chevy, fords from the 60's) does not make any sense in a modern all aluminum engine. I seriously doubt any have taken their engines apart to check for signs of corrosion in the water jackets, radiators and coolant passages.
You do not have to buy the Jaguar labeled product but at least make sure it is meets the specification that real engineers at Jaguar recommend.

 

Car Manufacturers do the CHEAPEST POSSIBLE THING to make a car not break down within the warranty period. It has nothing to do with "Best Possible Engineering". Plastic coolant parts are and were Totally Moronic.
Can makers' primary concern is to MAKE MONEY, not to make the ultimate parts while sparing no expense.
Hell, replacing most of those stupid plastic coolant lines with ten-cents-a-foot rubber lines would be preferable.
Jaguar pulled a knob when they decided on plastic.

 

Rough day?

How about the myriad of lawsuits around Dexcool?
"Sealed for life" ZF Transmissions that are no longer "sealed for life".
Audi acceleration problems.
Every plastic part that CeeJay and Ranchero mentioned.
The GM ignition debacle that cost lives.
Toyota failed braking issues that cost lives.
The Ford police cars that fill the cabin with carbon monoxide.
Never mind all the manufacturer recalls over the years, often identified by "internet engineers".

 

I'm not an internet engineer but I did stay in an RPI dorm room at one time.

 

Not at all. Of course there are recalls in any industry. Auto manufacturers know that their reputation is only as good as the last car their customers bought. Do you think the auto manufactures love to be making headlines on the evening news due to a recall ?
My point was why buy a $70,000 to $120,000 car and expect to be able to use cheap oils, knock off parts, cheap tires, rigging repairs and then complain about it breaking down or having other issues.
Just because some of these cars are available for less than 20K does not mean they will or should have the running costs of a Yugo. My philosophy has always been if you cant afford the correct parts and maintain the car according to schedule, buy a different car

 

^^^^^^ So remember, if your classic car needs an oil change or some lubrication, you MUST USE WHALE OIL!!!!!!!

 

Another totally pointless comment. Well done Cee Jay.

 

 

It was a totally valid and accurate post. YOU said that the vehicles are BEST when they use ALL ORIGINAL parts and such. It doesn't matter if the OEM stuff was vastly inferior than anything else available at the time. It also doesn't matter if the OEM stuff is vastly inferior to NEW tech. YOU MUST USE OEM AT ALL COSTS!!!!!!!!!!
THEREFORE, use non-vulcanized rubber tires, crank starters, non-laminated glass and gas operated headlights.
After all, the OEM stuff is ALWAYS BETTER. Right????????

 

The one thing I enjoy about car forums is the manner in which they allow the enthusiasts of a brand or model to come together; sharing their love of the car in a spirit of true friendship and camaraderie.

It is a truly a joy to behold.

 

Is the factory fill dexacool?

 

F type takes...

50% mixture of water and antifreeze, specification WSS M97B44 (colored orange) Extended Life Coolant.

 

Does Dex-cool cause the plastic cooling parts in our Jags to deteriate?

I've been reading alot of articles that say Dex-cool damages plastics over time,
(I also realize there was the GM issue but i'm not talking about that)

What is the best alternative coolant to use that won't damage the plastics of our Jags?

Thanks

 

So after endless reading, and looking at the replacement plastic cooling parts sitting in my living room,
I've learned that OAT contains corrosion inhibitors which in fact will destroy PA66 plastics, which is the
plastics our cooling pipes and systems use, (it is stamped on all my cooling pipes)

I highly suggest changing your OAT coolant flushing the system and filling with HOAT such as ZEREX G05
