big problem tlga yan pag mali ang kabit ng timing belt. kaya until now kelangan ko pa din ng alalay pagdating sa area na yan.

anong tsikot mo bro? timing belts drive the camshaft and crankshaft in sync and pag mali ang timing nyan, that really would cause a strain. normally what would happen e maccra ang mga valves mo dahil sablay na ang cycle ng mga piston na dinadrive ng crankshaft with respect sa valves na tinutulak naman ng camshaft.

honestly, medyo di related ang overheating sa timing belt. pero i think sa scenario mo e ung maling installation ng timing belt was enough to drive the car at low gear pero not at the higher gears, which then caused the engine to operate at a higher temperature.... guess lang... :p

yeah, since may signed paperwork ka na nagadmit cla na mali ung gnawa nila, they should pay for all damages they did.
