hi zerohero2,
thanks a lot for the information especially the pricing comparison, it was
really very helpful.
in regards to your overheating problem, these are what i can think of
apart from you eloborate above.
1) always use anti-freeze coolant. i was told by opel tech that the
ecotech engine and cooling system is critical to the type of coolant used.
do not use japs or other coolant type. in my case, i always use volvo anti-
freeze coolant which cost about RM28 per litre and follow the instruction
of mixture as required in the label.
2) check (visual) by looking at the reserve tank (do not open the lid of
the reserve tank) while the engine is running idle whether there is an
inflow (continuos smooth flow) of coolant back into the reserve tank from
one of the hose coming from engine side. try increasing the idling and you
should see more volume of coolant inflow compared to idling situation. if
this is visible than i believe you do not have clogging problem.
3) check also your spark plugs....if your last pomen used the correct type
since your last service or spark plug change. i had one bad experience
whereby this trusted pomen put in cheap and not to spec spark plugs and
caused my engine to overheat until the engine icon light up. spark plugs
plays very important role in dissipating heat in the engine. the correct
spark plug to use for Vectra 2.0i 16v is BOSCH type with code No: FR 8 LDC
cost about RM15 per pc.
normally the temperature indicator at the dashboard should be around 92
degrees C even in city driving.
well, check out the above and i hope it helps in solving your over-heating
problem.
cheers
