solutie curatare ulei ars, gudron

Recommended Posts

Salutare.... m-ar interesa o solutie pentru a curata un schimbator de caldura prin care trec gazele din egr-ul masinii. In interiorul schimbatorului se afla cca 20 conducte subtiri de dimensiunea unui pix prin care trec gazele din motor , acestea fiind infundate. Pt a inmuia aceasta depunere de pe conducte (ulei ars+ funingine+ gudron) ce solutie ar trebui sa folosesc?

poti folosii diluant, umplii un sfert-jumatate din teava acoperi ambele capete si agiti dupa care il lasi cam 10 minute, iar apoi prinzi de o sarma o carpa si o freci de interiorul teviilor eu asa am curatat valva egr si teviile aferente de la un logan diesel

Ambele solutii sunt bune. Si mai bine este sa se foloseasca mai intai prima, apoi a doua, apoi apa fierbinte. Se poate sa ramana curat.
