chasers are good and dr drift is pretty good aswell

Chasers is great but expensive, Dr.drift is booked out for the next 2 weeks, i need someone to look into my overheating issue, most likely a water pump change..

Whats symptoms? Losing water? How long till it begins to overheat etc?

The car has brand new radiator, thermostat, the block has been flushed out a couple months ago. Now it still has brown sludge built up in the new radiator, car warms up quickly then sits at around 90C on most short drive but if i drive for a long time it can get to 98C, so either the water pump isnt keeping up/is stuffed which was probably never changed on a 15yo car, flow problems? or possibly something to do with the head gasket?

Could be some air still in it its suprising how much problems it can cause. Id give it a real good bleed first before going anywhere. Is your thermostat opening?

Thermostat is new, after a drive with the car fully warm the top radiator hose is hot and the bottom one isnt even warm, WTF is going on?? im so over this.....going down to chasers 2moro so they can look at it :S

Ye its not opening if bottom one isnt warm. Common mistake is when you put too much off that gasket goo for the thermo you can jam the jiggle valve aswell which traps air.

well the car doesnt cook, it just sits hot and get hotter (90C +) as u drive for more than half an hour, should i just take out the thermo and drive the car without it to see if anything improves?

cheers

Looks like a flow problem, im just gonna take out the thermo and run the car without for a while and see how it goes and also run a radiator cleaner and do another flush.

I had the same probelm like you describe bottom hose wasnt hot and it would get to about 90 and slowly climb up. Was the thermostat and air in my case but yeah see how you go without it just make sure you bleed it! Wait until coolant is pissing out of that bleeding screw with no bubbles.

thanks for your input boostn !

Well i took out the thermostat earlier today, it had brown rusty sludge build up on the outlet side which connects to the bottom radiator hose which also had the same build up in it, on the block side of the thermostat it was all nice and clean with green coolant still inside the block, clearly no circulation or what??

Anyway i connected everything back up (minus the thermostat) and ill run that radiator cleaner through it over the next week or so..is there any better way of cleaning out rust build up ?

Yeah ill definately bleed it via that screw near the intake manifold.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
