Changed the radiator cap again

 

I had notice that the spare tank of coolant always have traces of coolant on the lips of it. It dried up and seems like overflow. However the reserve tank doesn't look dirty etc. 

Anyway, I think I just buy a new radiator cap and observe whether it can help or not. Maybe the cap got weak after so many years.

Plus, there is a new design. The symbol look more modern and it have a new part number 16401-36030. I bought one and it does feel great. Maybe it just look new. 

Remember that the cap is for 88kPa.

Good a simple DIY

Radiator cap

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.

Radiator changed in the nick of time

It is a great Raya holiday and I take this time to touch up the car, washing and cleaning the engine bay during this holiday, while wiping the engine bay and filling up water to the reservoir I found something funny on the radiator. Something look not right as it was colour red on certain spot of the radiator and after have a further view using a torch light I think I spotted a problem of leaking radiator.

The photo above show the location of the leak as colour red same as the coolant colour of Toyota. It is so bad that it somehow crystallised on the radiator. Then I started to get worry of using the car for long distance driving. I need to quickly replace it in order not to get stranded on the highway.

I send the car to the mechanics for a check and they informed me that the radiator need to be replaced and after a quick check with the his supplier, there are no stock and an order from Japan will need at least 1 month to reach. The cost is a mind blogging 2k. That is unacceptable to me and I think there should be a better way. I quickly contact Zul from SPT Autopart which specialised on cooling parts, via whatsapp he managed to confirm and get me an original Denso radiator half the price. I previously bought another radiator from him before, the response time are top notch and very efficient.

For those wanted to get the radiator can jot down this number 422173-2630 (Denso). This would be the part number for the radiator and it is a direct replacement on Toyota Isis.

Else you need to google the parts number by Toyota.
