Noodles anyone ? (heater matrix inserts)

[DamirGTI 345]

Stuff never seem to surprise an individual in automotive world !

 

The physics about this tubular swirl inserts i understand , but seen them disintegrated and migrated through the cooling system potentially blocking off smaller coolant hoses , damaging water pump seal , thermostat stuck open etc. 

Decided to pull them out ... cause they're plastic and OE should be metal which will be near impossible to find nowadays with Chinesuim made parts .

 

Now im not sure if it's just one strip of that turbulator inside or there's one in each alu. tube ?!

 

Also they say without the inserts the heater function will be less efficient , anyone tried without the strips inside if it really makes that much difference ?

 

Nissens and some unknown brand "made in the same factory with just different labels identical item crap" :

If id have seen that crap in mine it would have been out and in the bin , Volkswagen put a bag of desiccant beads in the expansion bottles  of  the 2011 on passats and eventually the bags split letting all the beads into the very fine matrix tubes blocking them . My brother was caught with it and its had 2 matrix's already as its hard to get it all out and once its in the matrix its new matrix time again as no heat.

its not dessicant, though it is silica to extend the life of the particular eco friendly coolant used.

 

the bags physically cannot split, they are perforated and have no force upon them.

 

the blocked matrix thing is super common as its not a full flow system like older vehicles like a 205,  to prevent them bursting,    poor maintenance and using tap water rather than distilled/de-ionised water soon makes the engine blocks corrode which leads to the silt.

They  can split with old age though usually around 10 years as in our case the bag  was empty and all the smalll bits were going round the lines and its super common .Our mechanic takes any of the bags he find out the expansion bottle to avoid it .all other manufacturerd can cope with tap water and good antifreeze Volkswagen just put that bs out to avoid liability as most manufacturers have aluminium blocks amd heater matrixes  these days and no issues.
