It's been a while since I last post, a year plus went missing. It is due to nothing much changes and less usage of my Isis for the past year. This time I bought a new radiator cap to replace the original factory fitted cap in order to try to improve the cooling performance.
The original factory fitted radiator cap was from Denso 0.9 without spring type, small head. The one that I bought also original parts but not made by Denso. Not sure the brand but still the small head and without spring.
The story started when I notice a drop in cooling performance after my last service. The coolant temperature are a bit higher and I notice some coolant on the overflow tank top and nearby the radiator cap. Hence I believe the radiator cap had lost it performance and hopefully by replacing it, the cooling performance will be restored.
The cost of the radiator cap? RM30.00 and I bought it from my favourite shop in Sentul. However, the owner had opened another branch nearby Batu Caves there. Google for Gateway Auto Parts and you can find it. They carry a lot of Toyota parts too.
