Hi all,

Long story short I have a coolant leak from my OEM cooling setup.

Turned out to be one of the end tanks leaking - where from I dont know at this time - could be end tank cracked (worst case) or could be just that the seal is gone. Will know more later.

My question is:

What is an advisable replacement item for my OEM setup which will achieve the following

  • Provide a higher level of cooling than the OEM setup
  • Look as OEM as possible (I dont mind going to a full Aluminium setup- just keeping it looking OEM is preferable)
  • Price can't be outrageous
  • Be able to cope with 35 deg / 40 deg days in SA in traffic ( I understand that this has more to do with the fan setup than anything else)
  • Fit must suit OEM cooling setup i.e. OEM clutch fan etc.

Cheers,

David

Not having massive cooling issues atm in normal weather upto about 27 odd degrees. After that the "Hot Fan" at the front of the car switches on.

All of this being said, I dont want to replace the std radiator with something that will only EQUAL the cooling capacity of the stock setup.

Considering the car is making probably twice the amount of power than the original motor made in that car; the cooling is probably a little underdone if anything.

1 such person here. A koyo radiator nor resides where my cooling pro used to be (lasted just over a year I think)

Yeh I was looking at getting a Koyo, but they are decently expensive compared to some of the other options on the market.

However, a wise man once said, you get what you pay for - and here is no different IMO. Heard a few bad stories about the 52mm thick after market items and them being no better than the OEM setup.

I have had a triple core China spec alloy radiator in my car for something like 5 years now. Much more cooling ability than the std radiator. So much so that I had to replace the thermostat imediately after I did the radiator, because the old thermostat must have been stuck open, which was working alright on the original rad, but made the engine run totally cold and use 100% more petrol on the new radiator. Fits well, never given me a moment's grief. Would not put an original plastic tanked radiator into the car in the face of that.

$220 delivered for mine, I think its a little thicker than what the stock one was but otherwise exactly the same as stock

Thermo fans are shit!

can't believe you said that

I could...

Anyway stick with the stock clutch fan/shroud set-up.

And do NOT buy a $300 radiator of ebay. If you want it to do the job properly you'll be spending upwards of $500 for a double/triple pass item. Most will still retain factory mount/shroud & fan without a problem.

Agreed I do not want a ebay POS

However, any recommendations on specific brands?

PWR make an awesome 3 pass I hear, however the price is a little out of what I want to spend and overkill to boot.

Ye the PWR one is north of 800 IIRC.

Race Radiators in Melb make one, I've got one in my GTS-R. Works very well.

Eeeeerrrrrr .....no....

In traffic, at the lights, yes you will. They spin and push more air than the clutch fan at idle. Some cars will rise in temp at the lights. If you had the fan spinning faster it will cool the car, at idle, in traffic. My op was about this situation, not driving.

get an electric water pump, you will gain power by freeing up the engine from spinning one more pully.

Oh and in my GTR - on a 26 degree day, 5 laps flat chat of the Thunderdome (so around 5:30 @ full noise), hottest I saw was 95 degrees using a triple pass core.

Oil temp was certainly getting up there however, but that is unavoidable.

    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
    • ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
    • And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.
    • No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.
