:flamed: This problem has me a little worried and confused... I just got my new car, R32 GTS-t (HOORAY!) and it is overheating :P , at first it wouldn't do it all the time, but now it does... its an 89' and has done 84000 k's. It doesnt feel down on power, doesn't blow smoke or have water coming from the exhaust, no coolant in oil, or bubbles in coolant. It will get really hot sometimes...which has me very concerned :warning: ... but then it will drop all of a sudden... which makes me think it is a f***ed thermostat. I know i shouldn't drive it, but i have to get to work, I get the car into speedworks on monday so they should diagnose the problem... hopefully. What do you guys reckon it could be?

Also, after the cooling issue is sorted of course, what do you guys reckon I should do to the car first? front mount, suspension, brakes... It already has an HKS pod and Kakimoto exhaust... the rest is stock... i think

Cheers

you have beed air out? top of intake manifold on rb20/25

Is that the little screw with a yellow "never open when hot" label on the inlet manifold closest to the front end of the car? What do I do, just take it out and put it back in or do I have to run the engine with it off?

Dammit! Shes a still gettin hot. I took the bleed valve off last night, then went for a burn, it was good, then the heat just started to rise, so I limped home hoping it wouldnt get too hot. Thanks for your help anyway GDZ1LA :( Anyone else have any ideas.

Still I may not have done it right and GDZ1LA could be right. Any help welcome.

9.5 times out of 10, if you're not using water, of have none of the other symtoms you say you've checked, you have a partially blocked radiator core. To flush it properly, needs a bit of explanation. Needs to be "reverse flushed." Take it to radiator repairer. They have right equipment and shpuld'nt be very costly. If you MUST do it yourself, I'll [reluctantly] try to write a fair description.

This is all good news as far as im concerned... they are minor repair/replace jobs compared to replacing a head or gasket.. cheaper too. By all rights if I had a cracked head/ or gasket damage, i'd be experiencing a major lack of power right? as well as milky oil, possibly steamy, smokey exhaust yeh?

To do it right, reverse flushing in car takes a bit of explaining, so I thought, seeing it's so easy to remove radiator, why not do that, turn it upside down, and use as much water pressure as you can, from bottom to top, allowing the water to escape, alternatively, from the filler neck, and the top hose connection point. That would do a pretty good job.

Put the water hose in the bottom radiator hose point, and seal it as much as possible, so that all the pressutr water has to travel up through the core to get to top tank. This is the opposite direction of flow to when radiator is in car, which is why it is more effective in removing blockages than flushing top to bottom.

ahHHhhh HUH!! mine is doing that as well! the temp gauge is reading just a bit above half, is this actualli normal/acceptable? it never rises above this point and isnt using any water, even after lots of hard driving, so would this be just a partially blocked radiator i presume?

just dont like looking at it so high , when my bro's R32 is reading below half!

thanks for any advice guys.

ps- josh what colour if your 32? seems like there is quite a R32 "population" explosion in perth ;) mines black coupe, and black sedan for my bro.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
