hi guys, my engine coolant is VERY low and i wanted to know can i mix different brands or does it have to be the same brand.

 

Should be ok to use any brand, there's one maybe prestone that comes 50/50 with water. Maybe you should find out why you are low on coolant instead of filling it.

 

......sure just don't mix colours. My Infiniti's have come with green coolant, so I should stick with green.

Just go to the local walmart or something and pick up the Prestone extended life coolant. Green coolant is green coolant which is what the dealerships all told me also but for peace of mind, the new formula from Prestone is able to mix with any brand and any color.
$8 a gallon.

 

The coolant must be for aluminum engines. Infiniti sells Warranty friendly coolant. My radiator failed at around 70K miles....I was stupid enough to put on one of those high pressure Nismo radiator caps on my Sedan..... result was a leaking radiator after 50K miles of using it.. It threw the CEL and I noticed low radiator fluid + coolant spray on the engine interior. The coolant system is too important to neglect...Find out why your coolant level is low!

 

^^^ +1 must be the formula for aluminum engines.

just go to the nissan or inf dealer and also grab a bottle of distilled water.

 

few days ago it was little low it was like 85% so i filled it with water until it reach the COLD line is this okay ??? or the newbie did something wrong :P

 

So, the Nismo high pressure cap caused your radiator to fail? That seems strange from a Nismo product.
