yeah you right , my car's previous owner has removed this T valve and also the fan auto switch ,,,,,,,,,,,,,,thats really strange ,,,,,,,,,,,,,but i will restore all that in original condition,,,,,,,,,,,,,,,,,,,,,i plan to buy a T valve and then this point came in mind that different engine run on different healthy temperature , by healty temperature i mean the ideal temperature on which it gives its peak performance,,,,,,,,,,,like diesel engine need high temperature , engines with cast iron block have different temperature , and same as with alminum blocks ,,,,,,,,,,,,,,so how can we mix this T valve ,,,,,,,,,,,i take this T valve from my cousion , he also have cultus and his mechanic has removed this valve by saying that your engine no longer need of this thing ,,,,,,,,,,,,,,so i am 100% sure that this T valve is original from cultus ,,,,,,,,,,,,,,,,i see some temperature reading engraved on T valve ,,,,,,,,,,it says 82 degree C ,,,,,,,,,,,,,, i dont know about it but i guess its the max temperature on which it works ,,,,,,,,,,,,,,,and i am sure different engine T valve have different temperature,,,,,,,,,,,,,so i guess use the one which is original for your car,,,,,,,,
some expert gave comments on it,,,,,,,,,,,it will be helpfull ,
