Pink Coolant Test

[m456an]

Did a coolant test using multimeter. Got 0.06V using - ve black terminal on Battery and the same using another earth point. The coolant is 5 years old but I only use it for local driving. I think it is OK as it is lower then 0.3V. 

 

Though I did the test with the car cold. Should l do the test with the car running with the radiator cap off? 

P. S

Though I have ordered pink coolant 5l from eBay for £32 much cheaper then from Toyota £45. Though it seems the parcel was sent to the wrong address.....

I have no idea about these measurements and how accurate they can be but if me I will not question the coolant but just replace it. Even no need to flush the system or get panicked if any small amount will remain inside, drain and refill works great and just stick to manufacturers recommended intervals for miles/ years and you won’t have any problems.

Will change, once I get the coolant. eBay seller has contacted parcel2go and they have agreed to get the parcel from the wrong address and deliver to my address. 

 

He said it was no easy thing to do.
