Hi All.
Loads of threads re EGR removal (L Series diesel)
However, here's a question I have not seen addressed so far (sorry if I have missed it!)
When you remove the egr assembly - you fit a connector pipe in the water hoses (coolant) that originally went to the EGR cooling system, fine so far.
The car heater matrix was always in 'parallel' with the EGR system, however, IMHO, the egr system applied a restricted flow ???? - hence causing the coolant to be biased towards the heater matrix. ?????
With removing the EGR assembly - would it not decrease heater matrix performance (especially if the matrix is slightly blocked (normal !) ????.
Would there be any advantage in inserting a deliberate restriction into the removed EGR circuit ? - I would 'suspect' there would be - hence biasing the coolant towards the matrix ?
Obviously, this depends on the amount of restriction of flow caused by the original EGR !.
Also, the flow for the IRD coolant is incorporated into this rather convoluted circuit. This may also suffer - however it is hard to tell as I have no real way of measuring the effect of removal of EGR and original restriction (if any of consequence) hence the original bias towards other parts of the coolant circuit.
Interested in your thoughts ?
