TOday i changed radiator of my car, originaly it had single tube copper with plastic tanks made by DENSO , it had been old and leaking a very small bit of water from upper tank. it was annoying me though never had heat up issues.
i replaced it with a same spec ,thicker wider aluminium and much bigger radiator. its also made by DENSO and was a bolt on fit. it has bigger fan motor ( double speed ) though the fan blades are of same size.
difference i feel is that now the radiator fan kicks in very rearly, specialy when im driving it never kicks in ( temp gauge showing the same reading as before ) and knocking has disappeared altogether while driving on petrol. i used to hear knocking in 3rd gear when accelerating from a very slow turn but now its gone...
feeling good till now....hope my car accepts it in longer run....
will upload pics soon!
