wow, even someone used merc coolant, luckily dont void warranty coz can void actually. Dont ever think using merc coolant means better cooling coz merc used it coz merc coolant is oem, not produced by merc n tested in merc engine, not in malaysia climate. But since being tested in merc engine, not a problem.
Engine if too cool also can cause problem coz pulley is working hard so that u loose power, bad fc n worst case, damage the engine. Too cool or too hot is not good for engine.
Thats why when people said 100% coolant for campro based engine means 100% coolant from the prtn weston based coolant premix with correct concentration, made by oem, tested by prtn, using prtn engine n tested in malaysia climate.
If 4l is needed then need to prepare 4 bottles. This coolant from prtn for campro based engined already tested to maintain the engine at its optimum temperature point, not too cool n not too hot.
Haishhh, if something happened then claim for warranty. But like i said, luckily being entertain, if not, totally void for life on engine. So, becareful next time ok. now i know the culprit of the engine problem case coz previously never mentioned used merc coolant.
