Re: Coolant/Spark ?? (1881 Views)

Hi,

Thanks for your reply again. Do you drain and refill or flush your radiator?

I see different brands of Coolants. Which one is alternate to Toyota coolant?

I have 1999 Toyota Camry LE (4 CYL) vehicle. As per owners
manual, I need to use Twin ground electrode platinum tipped spark
plugs. I see iridium spark plug(DESSO/NGK) in the market. It says that it was better than
platinum.

I do not know whether they are traditional, Twin ground
electrode or recommended for my vehicle. Does it harm my engine(motor), if I use
iridium spark plug?
