If the car only overheats at 100kmh +...

I warmed my car up to operating temp, stuck my finger in the rad, couldn't feel any flow of coolant

And the fans didnt seem to go on?

Also the top rad hose became hot but the bottom was not

Diagnosis lovely gents?

How long did you let it run for? were you reving it, cause if you leave it to idle it will take awhile before the fan will switch on. all hondas do.

Have you checked your thermostat yet?

If the engine is dead cold , it will take a good 20 minutes of idle for it to warm up enough for the rad. fan to come on.

Try this dude. Disconnect the fan switch(located directly on the SIDE of the thermostat housing - grey clip + 2 wires) and short it (use a wire or a paper clip) See if the fan comes on. If so , fan and switch is OK.

Replace thermostat as suggested above. And properly bleed all air from coolant system

Couldn't change it til I get home 2 syd thats where my tools are which means driving the car back from newcastle again which means stopping every 10 mins to let the engine cool lol.
I just took it to the mechanic, hopefully its just the thermo and not the whole radiator

cheers

If the thermostat won't open completely then it could cause your problem.

[Chriskoss]

yeah im hoping its just the thermo, well see!

[JohnL]

I would be surprised...

[Chriskoss]

Ended up being the radiator. They said it was 95% blocked, and needed new hoses and stuff too.
$645 bucks too! :O I just spent 500 on the damn car fixing a main seal too, god what a money pit

[omgzilla]

HOLY RIP-OFF BATMAN!

*Pats self on back for telling you to feel-check for radiator blockage first lol.

Could've saved yourself some serious coin! Would have cost you less than half of what you've just paid!

At least you're sorted now

[JetSir]

new rad n labour should only cost u around 300ish.

u mst of got a good radiator =D

[aaronng]

So, have you confirmed that the problem is fixed? Or does the needle still go up in temperature with the new radiator?

BTW, use Honda coolant next time to help avoid radiator corrosion problems.

[Chriskoss]

well for 645 bucks i sure hope the fukn problem is fixed.

every1 tells me 300 for a new rad.. but my rad was 350.. plus extra 2 fit it and a few hoses

called up another place they said like 450 so yeh i got ripped off for sure, but even 450-500 seems a shit load just for a peice of metal and some coolant.. sigh
