Thanks Guys , Your advises really helped me out. Radiator fins were deadly damaged right behind the bumper . SO i just changed the radiator and everything is back to normal
Would also like to share some price info that when i was searching for a radiator i came to know that there were two typos in new radiator one for Rs. 3500 and another one was 4200, Mostly in marked 3500 walas were available, But i was low on budget aur abhi salary bhi nahi ayee lol tou i went to plaza and i came to know a guy who was well experienced in this radiator fanda, He took me to the market as i told him that my budget is low, But mentally i was prepared for 3500 wala :D, He took me to one place and we found a radiator for 2800, it was almost like new but low quality, then he took me to another place and we checked for the radiator, they guy there showed us the radiator almost like new, he got that from hyderabad , i asked him about the details and he told me ( K japani jali pe kaam hoker wahi se aik banda le kar atta hai and meri guarantee hai k kafi arsay aapki jaan ***** jayegi ) the radiator is working fine Mashallah and it costed me 2200 Rupees
so kuch savings hoi and my car is flying now .
