Recomended Coolant For Gt T R34

[shehris]

Hi Guys, just bought GT-T R34 pretty much stock overall. Noticed the coolant is way below the low line...is there something you guys recommend and from where I can get it or can I pick up anything from the shelf.

Thanks

There's something I always hate, having to topup unknown existing coolant risking a reaction between the 2.

The best you can do is Genuine Nissan Long-Life Coolant (LLC), from a Nissan dealership. 1 litre of concentrate cost $10-$15 and makes 2-3litres (depending on a 50:50 or 66:33 mix of water:concentrate).

The cheaper option is Nulon concentrate that meats the Nissan specification (Nissan LLC I think is the technical name)

get the Nulon Pre-Mixed (green) coolant ..I paid $20 per 5l canister just the other day. Don't just top up.

If you've got an hour or 2 I'd highly recommend taking out the factory radiator and hosing the fins down (carefully) mine was completely blocked with bugs and dirt.

Flush the system, and use genuine Nissan LLC. But don't mix it stronger than 60:40.

If you use the genuine stuff, and change it every couple of years, the alloy bits won't corrode, simple as that.

Hey guy any chance you would know how many litres an r34 gtt would hold as im replacing the radiator and dont know whether to buy the 5ltr LLC ($62) or a couple of 1litre ones at $16 each

Its inbetween 7-8L (cant remember) you dont need 5L because you have too mix is with demineralised water. I suggest 4L or less of LLC and the rest demineralised water too get a 50\50 min or less. To much coolant and you wont be helping your engine cool at all.

it takes 9 litres for the whole system but you will struggle to get even 3l in there unless you properly flush the whole cooling system (there's a few threads about that too) Don't forget to bleed the air.

The nissan manual says to change coolant every 2 years. Is this still necessary if you're using coolant like Penrite or nulon which has improved over the years? It says it lasts 500,000km which seems hard to believe lol.

I think you'll find that with modified cars, the radiator has to come out more often than once every 2 years, meaning this generally gets cycled pretty well lol.

If I had a car that had been sitting for 5+ years I'd probably flush the coolant. Coolant really shouldn't go off. It's main purpose is to inhibit rust and stop the whole thing from freezing, the latter not really being an issue here.

Ah ok. I put in a new radiator previously and flushed the coolant out at the same time but it is getting to that 2 year mark. My car is pretty much a daily driver in a sense but haven't put heaps of km on it.

The only other time I changed it is when I noticed it had become discoloured after a few track days (it was .. yellowish). So I drained and refilled the rad. 

I think most people are in this situation. It's not like the car ran any cooler after I changed the coolant either. I'm gonna go with "If it makes you feel better, change it!"

If you fully flushed and filled it's probably good for 5 years. I would not push it any further than that. Generally speaking coolant is more by time than by mileage. Rust wants to happen whether you're driving it 50,000 km or 80,000 km.
