Most of us are familiar with how much a pain in the ass it is to get to the engine block drain plug. Is there any other way of draining and flushing the engine block without taking off the exhaust manifold?

I have a new radiator coming, but don't want to install it only to get grubby rusty shit from the engine blocking it up.

Perhaps removing the thermostat? Can anyone tell me how to do it cos removing that seems like a mission as well.

Suggestions please.

Just purchase that "Radiator Flush" stuff, run it in ya cooling system for like 10 minutes or something and then flush it all out with water. Once the water is clear and clean, chuck some concentrated coolant in there (tectaloy) and use the bleed valve (connected to intake plenum) to bleed out air. Once it's full take for a drive, then top up after as per needed.

Cheers,

Hey Guys,

Can someone here tell me where the bleed valve is on the R34 engine. I just got my car the other day and found the radiator was dirty as shit so i ran some radiator flush through it (Still hell dirty) and then i refilled with a coolant premix. Anyway i took it for a drive and when i got back i could hear water boiling (although cabin thermostat was fine). I assume this is because i didnt use the bleed valve to remove air from the system. Photo's would be great if anyone has them.

Thanks in advance,

Will

the way i flush them is i pull 1 of the heater hoses off and stick a hose in it and turn it on till its just clear water flowing out of the top where the cap goes. The way 2 bleed them is get a 1.25L softdrink bottle clean it the cut the bottem of it and wrap a litle bit of tape around where the cap goes 2 make a good seal in the top of the radiator then pour coolant or water in till its the highest part of the system the take the bleeding screws out to let the air out hen the coolant starts flowing out at a constant flow put the bleed screw in and the pull the bottle out and put the cap on. then wash the coolant down that came out of the bleeders and on the radiator so u dont et the white stains. Hope this helps

No problems mate. Also check your hoses, hopefully your system will not look like mine :wacko:http://www.skylinesaustralia.com/forums/R3...le-t237858.html

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
