Ok anyways, just had my car serviced a week or two ago. New coolant and new water pump. Driving home yesterday I noticed some white smoke drift past from near the front of the car while stopped for a moment, because I was close to the car infront, I just passed it off as some random smoke from the car infront or from beside me (3lane each way road).

Thought I should keep an eye on the temp and oil pressure gauges just incase. Didn't see anything else until about a minute or two later when I saw white smoke coming from the bonnet, took it straight out of gear (it stalled then) and pulled over. I was watching temp gauge regularly (every 20 sec or so) before that and didn't notice a change in needle position prior to this. Check radiator, zero coolant in the radiator. Got a tow. Problem found this morning was a crack in the plastic radiator end tank, apparently drained all coolant out, no coolant circulating may be why the temp needle didn't seem to change. Didn't notice any white smoke out back of car while driving (although I don't look out the back much, and have dark 20% tint).

Is the random cracking of plastic end tanks common in R32's, skylines?

What are my options, 2nd hand radiator (probably run into same problem), new radiator $$$$??? Car is being tested tomorrow morning to see if internal damage is a result of the overheating.... poor compression, blown head gasket, etc.... I'd hate to lose an engine on something this stupid. :D:D

ANyways, gimme your feedback...

new tank should be fairly cheap. they will flush and clean the core too while the tank is off. top tanks cracking is pretty common on lots of cars. not just 32s.

the factory temp gauge is pretty useless. it stays dead in the middle from about 65 degrees until about 110 degrees so as not to alarm the driver. it's an idiot gauge.

i would say your engine 'should' be ok. what was the oil temp like?

ive seen full alloy radiators at autobarn for like $299. i had the top tank on my radiator replaced for $260... i hope things work out for u.

Ron, I wouldnt touch them with 20 foot clown pole...and you know what my job is....

take it to a radiator specialst, and get a new tank and a good clean of the rad... Fact is the standard R32 radiator is pretty good for what it is, no need to put in an aliminium one unless your chasing some serious power

Just buy a second hand one, cheaper IMO.

Get it flushed from a radiator place and away you go :D

And Richard - totally agree. The gauge is absolutely pointless.

Mine behaves just as you said and its an RB25 sensor.

Thankgod for the PFC Handcontroller :)

I decided to go with a replaced top end tank, not the best solution, but is relatively cheap and I get the car back on the road quick smart, which is my main aim.

exactly wat i did mate. nice n easy

in the HR31 skylines, they have a single core radiator.

in the australian delivered they have double core radiator the same size.

all the imports like r32s silvias etc have pissy little radiators.

My point being they were not intended for Australian conditions. They have to be in tip top shape to handle 40+ days, i.e. good working pump, no leaks, working thermostat. That said, it should be common practise for any car of age.

i went to the Just Jap Cooling Pro radiator, and noticed a 4-8 degree drop on an average drive, today was 40 degrees and the temp was sitting on 80degrees the whole 30min drive home from work. that rox the sox of any other car ive owned, turbo & non turbo

Mine did this some years ago.. It had some where around 100,000km's on the clock at the time. Its now done 225,000km's.

The same as you.. I did a recent service that replaced all major hoses, waterpump, cam belt etc. Saw what looked like smoke. Pulled over but I managed to track it down to the snout had simply gone brittle and crumbled under the new hose clamp. :)

I wouldn't be too concerned about internal damage from overheating, these rb20's are damn tough.

When I first got mine ~5years ago it had a dodgy guage temp sender that had the temp sitting on 1/4 the majority of the time and in hot weather 1/2. It ran 2 x 12" thermo's. During hot weather the car would feel quite sluggish and spew its coolant out. After replacing the temp sender it turned out the car in hot weather was driving around ON THE H!!! It was like this for a whole summer. To this day I am still amazed the motor was fine.

But yes.. back to the radiator tank... My top tank was the buggered. Natrad replaced the top tank for $90 inc labour + coolant + rodding the radiator.

So head down the local radiator workshop, they should know what top tank to use. It does look slightly different, most likely of an R31 or something, but it works, fits and looks tidy so thats all that matters.

----

The R32's run a thicker radiator than the Silvia's etc.. I believe the rads are identical to the GTR.

Measuring the side of the core mine measures up at 50mm.

It copes fine with hot weather, with the a/c off it will peak at around 87 in traffic or up a long hill, general cruising it sits on the usual 84degree's that it sits on even on those 4degree winter mornings.

With the A/C on it will peak 95 generally or 100degree's if really stuck in traffic on a 40degree day. But it doesn't go much over that and once moving a little the engine temps come down really quick to under 90.

BUT.. You can't beat the justjap rad.. Simply awesome price/performance.

Hey guys, just an update. As said before I had the end (top) tank replaced. The engine tested fine, did a CO2 test and it came back perfect, so no engine damage *phew*.

I think I have been driving around for a long time (winter and last summer) with very little water (due to a stuffed water pump leaking profusely through the weep hole). The temp needle never went over half way, even in hot weather and stop/start driving into the city every morning/afternoon. When the water pump was replaced it was noted there was very little water. I think the car has been continually running hot pretty much since I got the car, and why I think the end tank finally gave out after continually running hot.

I will check the radiator fluid more regulalry from now on, because I can't trust the temp needle at all.

Good JEsUs! thats truly insane, makes me feel better about a short overheating stint my RB saw once

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
