View Full Version : Funny noise off the rad.
After a hard run, when I stop the engine, she goes "Glug, ...., glug, glug, ......., glug, glug, glug, ...." etc., etc., for about 1/2 an hour.
The coolant system seems full and there is, clean, fluid in the expansion tank. It's about the max. level.
I'm not sure if she always did it but I never noticed it until a few weeks ago.
Diagnosis doctors?

glug glug ???
are you sure it not a sound of boiling?

:duck: uh o :D

Could be boiling but the temperature guage never goes further than 55% of the way up.
By the way she's running like an absolute dream!
C'mon, gimme the bad news?!?!
:duck: uh o :D
LOL! You just turned into every machanic on the planet! :)
You just left out the:
1: Shake of the head, whilst you wipe your hands on an oily rag and look into the engine bay.
2: "Tsk, tsk, tsk! That's gonna cost you mate!"
3: "What f!ckw!t did that?" as you point at something inside the engine bay that I, clearly, fiddled with recently.
C'mon mate, break it to me gently? This is my baby!

it's white mate might as well scrap it.
i'm sure it's nothing worse than a buggered thermostat.
come on nick help the guy out he's got enough problems owning a white one. :duck: :duck: :duck:

You are going to get such a slap :gay: the next time I see you! :rant: :gay:
You missed out the "Sharp intake of breath whilst shaking the head & wiping your hands on an oily rag"
A respray should sort it Ian

Dont pay any attention to the noobs here :duck:
Make sure you are :-
1. Using Distilled/de-ionised water (rainwater for a good substitute)
2. have at least a 30% antifreeze mix (lowers the boiling point and acts as a lubricant
If you use tap water it will boil much quicker and leave deposites when it does such as lime scale in the small channels in the rad core
Also change the thermostat and if it doesnt already have one drill a small 5mm hole in the flat surface of it and if it does but has a small ball on a wire placed in it pull it out .. this helps to aid bleeding the system and prevent airlocks and will do virtually nothing (if anything) to effect warm up times

Ahah! :bigeyes: I recently fitted one of Nick's BLING top rad. pipes and refilled the system with tap water! :banghead:

Woah Hoss! run the drill a small 5mm hole in the flat surface of it and if it does but has a small ball on a wire placed in it pull it out bit past me again please? With diagrams and pictures. If I go drilling holes in things I want to be sure that noone says, later:

See, I'm not stupid, I just do a good impersonation of stupid! :)
Cheers Ed.
See, I told you! It would have been a real shame if we'd lost your expertise!

Ian, a man of your caliber should be using Forlife coolant, none of this water/antifreeze mixing malarky.
Drilling the thermostat isn't really needed if you take your time refilling the coolong system.
The small amount of tap water you put in won't have any effect on the cooling system, Ed's starting to sound like Chris Wilson :bigeyes:
Fit a new rad cap (none of this bling higher pressure ones either) and a new stat and go from there.
We've got a car in at the moment with the same symptoms, but that's definate BHG :crybaby:
is tap water a complete no-no then? I'm running 50/50 tap water and Motorcraft Super plus 4 ethylene glycol.. which i think is similar to forlife..

From what I have read "toyota forlife" is the same as any Etholyne Glycol (or how ever you spell it) antifreez the only difference is its red and alot more expensive.

Right! I've got the car going in to get electric fans fitted in a couple of weeks. Yes. I know, I'm a wimp but if I remove the rad. myself to fit the fans I have to remove the cooler pipes for the AT cooler and then refill the AT later and I can't get under the car, on my drive to do that, so she's going in!
I'm gonna get him to flush and refill the coolant whilst she's in. Is Forlife just the same as Ethylene Glycol or is it the bees danglers?

My understanding is that it depends on how hard the water is in your area: in the West Country, we used to be able to use tapwater pretty much with impunity, whereas here it's as hard as nails; use tapwater a lot in a hardwater area and five'll get you ten that you're overheating within a few months due to scale buildup.
Safest way for my money is to get some de-ionised from a chemist: Boots keep it at around £1 per gallon - worth it ten times over for the peace of mind.
Just to add my little bit of useless info. Since I had my HG fixed nearly 40,000 miles ago it has only ever had ForLife in it and so far (touches wood) it has had no problems with the water system since then. Prior to that it had only ever been serviced by Toyota and would have had ForLife in it. It now has nearly 140,000 on it and has only ever blown one HG (am I tempting fate???).

tisk you should know better than to go around saying things like this.

Here comes the science:- :duck:
If you flush and refill the cooling system with an anti-freeze/water mix then you are likely to use about 2 litres of anti-freeze and about 4 litres of water. Now the amount of limescale that you get from 4 litres of tap water is going to be pretty minimal (just think about how much limescale you get in a kettle and how many gallons of water it takes to produce that) and of course once the limescale has come out of the 4 litres then that's that. So the conclusion is that there is no real problem with using tap water,
UNLESS
your car has an a cooling system problem, so that you are continually topping up with fresh tap water and by doing so are introducing more limescale into the system.

I used to get this with my GT4. When fitting my downpipe we had to lose all the coolant and then refill again using Forlife.
Now the coolant that came out was very very dark in colour and must have been in there a long time. Topped up with nice fresh pink Forlife and hey presto, no more noises! It was purely the fact that it had very old coolant in there which was probably struggling to do its job.

That does it it's getting a full load of Forlife!
