A few questions about Radiations in the R33 GTS-t:

I noticed a few months back that their seemed to be what looked like dirty water splashed on the cover where the cam gears are, also on the side of the stock airbox. Didn't take much notice of it as I had driven through some mud and thought it had just splashed up or something.

A few weeks later I did a coolant change and then headed to Wakefield and kept topping up the coolant after each session (about 200-300mL at a time) just to keep the level in the overflow bottle up to 'max'. It appears that coolant is leaking out of my radiator (im guessing only when the temperature is up) on either end of the top part near the hose and the airbox.

The gauge on my dash for engine temperature still sits at the normal position (went up slightly at Wakefield after 80+ laps in 6hrs) but apart from that daily driving doesn't appear to be effecting any temps.

* Is this a common problem?

* Will things be ok if I just make sure the overflow bottle level is kept up on 'max'?

* Is their a certain part of the radiator that can be replaced/fixed or does the whole thing need to be replaced?

* If it needs to be replaced, what brand, how much and where from? I have looked on www.Greenline.jp and of the 3 available for the RB25DET they range from ~$800-2,000 depending on brand/size.

Feedback?

you may not be able to recore yours, i know mine is in similar condition and went to get it flushed... i was told there was too much stress cracking in the plastic end tanks, if they pulled it apart the force needed may break it completely!!

try ABC radiators off mulgoa rd, maccas side of ford dealership in an alley/industrial complex

im currently looking for somewhere that will provide just the core in bigger size as i can make my own end tank out of alloy!

Turns out the top tank has a 2" crack directly behind the cap where you fill it up which under high pressure/temperature it is leaking. Went to 2 places to get quotes.

#1: $95 in parts or $280 fitted.

#2: $120 in parts or $200 fitted.

I could probably do it myself with about 2hrs of mucking around but i'd rather get it all done professionally so i'll get #2 to fit it all up tomorrow.

You probably need to visit a Skyline specialist :D

The reason I say this is that *some* will have an RB radiator already lying there, cored and essentially brand new so they can install it and you don't have any downtime waiting for yours to be recored.

Should be a coupla hundred exchange.

    • The attached document is fine. I just downloaded & opened it.
    • Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks
    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
