Just wondering if anyone else has experienced snowflake or thin rubber bits in their coolant and if so where did it come from? I suctioned out some coolant today to add redline water wetter in anticipation of a road trip and in the bottle I saw rubber bits again. I've previously shop-vacced rubber chunks out of the Rad inlets.

Virtually every hose that can be reasonably reached with two human hands has been replaced...what did I miss? the only thing I can think of is that the hose(s) to/from the heater core might be disintegrating? I'm at a loss I've spent likely half the money on flushes and coolant filters then the cost of a new rad at this point haha.

 

The ones that can't be reasonably reached

Those are not that bad to replace of you remove the balance tube.

But how likely is the interior of a coolant hose to flake away after 100k miles? I never thought to examine the inside of the ones I did replace.

 

Flaking seems plausible, at least. And, besides, were else is there rubber in the system except the hoses? I can't think of any other rubber bits offhand.

Your car is giving you a warning. Whichever hose it is will blow at the most inconvenient moment if you ignore it. Renew every hose, including heater, cross pipe hoses, breather tube hoses, question mark pipe hoses, heater pipe to rad bottom return hose, question mark pipe hose, bottom hose etc etc. It is not the mileage, it is the length of time that they have manfully stood up to the engine bay conditions.

How many times do we say that ?

Off topic-ish, but adding water wetter on top of regular coolant is redundant. Coolant already has the same stuff already mixed in. More is not better.

 

It doesnt run 50/50 at the moment which is why I use it.

 

It could be leftover Barts rad stop leak garbage solution that Jaguar recommended using. Try a rad flush if it continues.
