Started to work on another NSX from last week.
The service menu is to carry out the Eng Refresh, Health Check, Cooling Sys OH, etc.
As I have never serviced this NSX, started with the Health Check or I should say I already spotted big issue on arrival.
When the owner arrived at my place (eng still hot), the coolant level was already below MIN.
After cooled the engine down, the coolant level went down further to this level.
The owner told me that he checked the level before leaving but noticed the smell of coolant on several occasions so seemed like leaking slowly in the past.
Once again, it was leaking from the radiator.......
Unlike most of the leakage, this one looked to be leaking from around front centre bottom side of the radiator so possibly something hit the plastic tank through the front opening???
Having said this, this NSX is the face lifted model so it has meshed barrier at the lower end of the front opening so very unlikely for something to be able to damage the bottom tank.....
Any way, another good example.
Please have your radiator checked and replaced before it fails.
If you think you are still fine because you own face lifted models (2002 – 2005), think twice.
This NSX is the face lifted model.
Making paddle on my garage floor....
I only placed the order for the Koyo Racing radiator a few weeks ago and now I need another one very soon so contacted the same vendor in US.
The shop told me that it is on back order at Koyo USA with unknown lead time....
There are several vendors selling the same V2032 Koyo radiator in stock in US but I have no experience with them and after discussing this with the owner, we decided to buy it through 'drmikey' as he can get one for us. Just waiting for the delivery.
Thank you for the prompt support drmikey, and as I dealt with him on several occasions, the owner was also happy knowing that I had good experience with his company.
The seal at the header tank cap was also dead. The owner already had new one bought through me so it will be replaced.
As I didn't know whether the air managed to get inside the cooling system or not, checked all four bleeder points and fortunately, there was no air at all so that was a relief.
As a precaution, carried out Eng Block test as well. Before/after the test, the fluid stayed blue with no hint of yellow tone so no exhaust in the coolant and happy with the head gasket.
(Should have used the same lighting before taking the photo.....)
As I'll be draining the coolant for the Eng Refresh, just topped it up with soft water in preparation for the test driving session before the Health Check.
