1st one: Your car could've been serviced at 'Quicks' service center (part of Zaren Corporation) or had Zahren oil used by some random service station @ 50,000kms on 23rd July 2001.
2nd one: Your Radiator core has been changed on the 23rd January this year.
3rd one: LCC (?) was done also on the 23rd Jan this year.
I don't think any of the above would have any impact on the condition of your car suffice to say that your radiator for all intents and purposes should be in top condition.
