What is reccomended coolant for proton persona 1.3 meridian

Remove oil filler cap which is normally on top of the rocker cover look at underside of cap, the side that goes into rocker cover, and if it is covererd in a white oily substance or if the tube that the filler cap goes into has the white gunge in it yo have oil and water / coolant mixing in your engine

The lubricating and cooling systems are isolated from each other in your car. They should never mix under normal conditions. They mix typically when a crack in the engine block exists - or - if the head gasket is damaged. You will probably find the there is coolant in the oil pan, too. A white / frothy substance on the dip stick will be evidence of this.

A head gasket replacement can be a costly repair - but often significantly less than a cracked engine block. It can require a fair amount of work to determine which caused the problem. Depending on the age of the car, mileage, etc. - it may not be worth fixing / replacing. Consult a trusted mechanic to help you best determine your options.

Good luck!

Under the dashboard, right side of driver for RHD. The cover has good labels of all fuses.

just the hose should do it

the radiator has a transmission cooler inside it and sometimes they go bad so transmission fluid mixes with the coolant. if it is then need to replace radiator

Coolant is oil based. The oily mess in the overflow could be very old coolant. Or it could be engine oil from a leaking head gasket.
The rusty stuff on the floor inside the car could be from a leaking heater core.
