Dear All, a question to ask,
I opened my radiators cap and found brownish substance under the cap and thin oily film on water top. what could be the possible reasons?should i be concerned? Gasket weak ha ya transmission oil mix ho rha? ya servise wala diesel andar chala gya radiator k?
this all happened after i changed my engine oil from a shop , previously it was using Caltex formula 10W30, i poured shell 10W40 as its summers.
the guy at oil change also pressure washed my engine bay with diesel, and surf.
the car in question is Suzuki Baleno, 1.3 liters, 2005.
any help is highly appreciated.
