Time for a good service

Last evening after I switched my thermostat for a good one I filled it up with 1.5 liters of this coolant, 1 liter of tap water, and the rest I filled up with the old rust-brown coolant that had been in the engine for the past few months.
I to am interested in why not to use OEM oil filters, since I have stuck with those since I have the car. I dont see why they would not work properly on a stock engine.

You put rust coloured dirty coolant back in the engine? You need to flush that crap out until the flushing water runs clear and fill with either a 50/50 mix or Toyota Red. If not, you will get severe corrosion problems inside the engine's and radiator water ways, and accelerated head gasket deterioration. You should also not mix different coolant types.

As for the OEM filters, if you read the post I put up, my Toyota dealer says that Toyota GB have switched filters for the AE86 filter part number. This filter states on the box "NOT SUITABLE FOR 4AGE ENGINE". I'm not sure if this is the case in Japan/USA/Europe etc, but if what's printed on the box is an issue to me. Plus the Toyota filters are far more expensive.

Therefore, I don't use the Toyota filters. The quality of the Nippon Micro filters is better anyway.
