Suzuki alto over heated after timing belt change

1) what does the mechanic say? 2) yes, a water pump should be changes when the timing belt is replaced, it is cost effective to do this because the labor is already mostly done and the water pump is a wearable part that should be changed at regular intervals 3) in you case, hard to say what caused your car to overheat- nothing directly related to a cam belt but many things can be disturbed during the work and maybe something was not put back correctly- like a fan belt put on too tight- or somethin'- maybe it was just time for the radiator to go, sometimes events have bad timing like that 4) get the garage to address the issue, I hope they are honest-

thanks, he said he didn't change the water pump because he didn't need to. he's saying it isn't his fault this happened, but it was fine before they touched it. its never had a problem. then all of a sudden they change the timing belt and its now over heated

would you say the water pump not being changed could of caused this to happen?

An 11 year old radiator can Overheat or "split" at anytime. I assume the vehicle has approx 70-80 k kms. If your changing the Cam timing belt as the required, service maintenance, 800 cc Alto 3 cylinder After 70K it will be a risky affair. Regards
