I generally buy parts from Honda House on montogomery Road or Shakeel Autos in Township. Get the Original Honda or OEM will cost more but will be peace of mind.
Secondly people here tend to remove Tstat valve in this country even if there is nothing wrong with their car.It doesnt necessarily means that the meter was reversed. Its because of stupid mechanics.
What kind of idiot that mechanic is who says dont use Coolant. I mean I have been to mechanics that are worse but even they say you can use coolant its better but they never insist you to use plain water... This guy deserves a medal.
Also Kabli parts are the worst to use. I always try to stay away from them unless and until the New part is hell expensive or not available. Its useless to put Kabli suspension parts, engine parts, radiators and tires. They are already used and in fact sometimes in worst condition than the part you are actually replacing them with. And most of them are repaired. There are shops in Bilal Gunj who work day and night repairing shocks, etc.
Its Ok to put Kabli windscreen or lights or a door handle but other than these its penny wise pound foolish.
