i notice a dramatic raise in both water and oil temp on the way back from vic market, so i quickly pull over to the side of the road....there was no leaking at all

i open the cap with cloth......lots of steam coming out and no coolant in the radiator, which is unbelievable :rofl: anyway, i managed to get few liters of water and pour into the radiator. this has quickly solved the temp problem (but still raising slowly)

my question is:

1. is it normal to have bubles when you pour water into radiator???

2. should i flash out all the coolant as i have seen some little dirt, dust or whatever it is in the radiator

3. i check the coolant about a month ago....and it was full.....so what cause the coolant to evaporate???

PS... i have got PWR 57mm aluminium radiator in my car

thanks

Daniel

well, it sounds like you may have a busted head gasket, or cracked head...this is what we call..DRAMAS!

think about it....if the radiator was full...and now its not...and its not leaking externally....that means its leaking internally. the coolant has to go somewhere, it doesnt just disappear.

remove the sparkplugs and find radiator pressure tester. this is a tool that goes on the radiiator just like the cap and you can pump in the required pressure, when you get there, the guage will probably drop, and if you look in each cylinder, you will probs notice one filling up with coolant. not good.

it is normal to have bubbles in the radiator, however, they should die down as the air gets bled from the system....but, if its constant bubbles like a spa jet, then that means combustion gas is going into the coolant system and blowing the water out.

what does the oil look like?? any water in it?? any oil in the water?? if this is the case, its more likely a cracked head then a head gasket.

hopefully, there is just a leak somewhere you have missed...otherwise the head will have to come off.

cheers

just for future ref.. in case you don't know.. cold water into hot engine + keep driving, can mean death to the engine... even if it was something else in the first place.

The car really should be at near cold temperature to add cold water back into the system. Otherwise you are adding cold water to a hot system, which of course can crack the head on its own.

hmm....ok....thanks for the info guys.....i took my car out for a spin to see if temp raising high...but my car seem to be fine today......

Predator: thanks for the tip man.....i will remember the tip you gave me today......i will take my car to the workshop this firday for the professional to check out my car....hope i didn't do any damage to the engine

cheers

Dan, should keep away from tap water too... should only use distilled water. I think the alloy radiators are even pickier so maybe get benno to flush the coolant system and refil with alloy radiator friendly coolant :D

thanks for telling me that marcus.....i just drop my car to Ben........i will have to keep my fingers crossed whole night....ben is gonna to tell me what's wrong with it after he checks the car out tomorrow. hope it's not the head and gasket......just something simple to fix

hey marcus.....you got to show me your car one day.....want to see how tough your car is with tomei cams......coz if i cant get my car sold by july....then i might put a pair of tomei cams like your into my car

    • Didnt realise RB's had more then 1 head.
    • 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.
