New Tires and New surprizes

[Demfer]

Picked up a set of Nokian WR-G2s for my 08 EX35 - Can't we to run these through the snow. Unfortunately I had a look under the hood today and found a surprise!

It looks like coolant is praying from a radiator bolt/screw? Is there any DIY solution to this? It doesn't look like anything is leaking but there is defiantly fresh spray under the hood.

After a bit of research it looks to be the "Air Relief Plug"...

Why would this be leaking?

[XIS]

O-ring. Dealer replaced mine too and I also didn't know it was leaking (just barely spitting)

I have the same problem too but my dealer said its radiator hose?.???

Sorry to hear about your mysterious coolant leak--hope it really is just an o-ring!

On another note, congrats on your tire decision! Seems you and I are the only ones here running them--in spite of the fact there aren't many great tire choices out there for these cars.

Keep us posted on how you make out with the coolant issue.

Just bought the o-ring from Infiniti dealer, cost less than $4, will install it tomorrow.

FXist keep me posted with any special installation directions. I imagine its very straight forward

Pretty straight forward replacement, but make sure do it when the coolant is cool, because a bit of the coolant will gust out when you remove the plastic screw. Took me like 2 mins to replaced it. cheers

Do you have a part number by any chance? I called the dealer in boston and the parts guy was clueless without a part number.

[FXist]

Part number 21481-18000 cost $3.29

What is the purpose of this Air Relief Plug?

[FXist]

No idea
Maybe more things for us to fix

Im thinking its one of the plugs which will purge the radiator when its drained or flushed. I think there is a second relief somwhere near the radiator hose as well.

Thanks guys, the air relief plug on my EX35 started spitting some coolant last week. Glad to know it's an easy fix!

I ran the Nokian WR-G2s on my '08 after the original Dunlops left me in fear for my life in the snow and the Yokos I ran after that weren't much better. The Nokian's were the best of the three, but I still felt less safe driving my EX in the snow than pretty much any other vehicles that I've ever owned. And it was AWD! Luckily it only matters a few days a year. And even though they too are supposed to be all-year tires, the G2s wore out even faster than the others.

Now I need tires for my '14. It has the 19" wheels and the G2s are not available in that size (245/45/R19 98V). Frankly, the stock Bridgestones were fine last winter, and were terrific the rest of the year. I'd gladly put them on again, except the $1200 price for a set gives me pause. Actually just about every decent tire is $1200 in that size. That's something you don't research ahead of time when choosing your options. Since I typically only get 20k miles out of a set of tires, with mounting etc. I figure they cost me $72 a month! Or $.065 per mile! Ouch!

Any 'spirited' drivers out there know of a worthy replacement for the Bridgestones that don't cost as much?

A lot of folks complain about the Bridgestones, but I got over 40k out of mine and thought they were pretty good, but like you choked on the replacement price. After hours of cross comparisons I bought a set of Hancook Ventus S1 Noble2 tires. They are top rated on Tire Rack as an all rounder, are less expensive than the stock Turanzas (19's) and I think handle as well or better both in the dry as well as rain and snow. I ran them last winter without difficulty in New England. They are smooth on good roads, but can be noisy on bumps, but not exceedingly so. I've put about 20k on them so far (yeah, I drive a lot) and will probably get another set in a year or so.
