brown coolant

I've just bought my car as i'm sure some of you are aware, the other day i was giving the engine a quick look over when i undone the radiator cap i noticed the water was realy dirty and brown i was thinking of giving it a good flush through and some fresh anti-freeze but i'm worried i might open a can of worms and the coolant starts finding its way out of places it shouldn't, what do you think i should do?

Re: brown coolant

First thing I thought was head gasket as sounds like you may have oi in your coolant.

Get it changed either way, but would also advise getting engine checked just to be on the safe side.

Havea look at this thread that Darren wrote for blown gasket symptoms;

Re: brown coolant

Was thinking the same Wayne to hopefully it isnt blown. How long the coolant in the car? and whats your mileage? on odd occcasion if coolant never changed it can go a dirty brown but would really be the case if it were in their with a lot of mileage and never changed from the car first day since it was new

Re: brown coolant

Thanks for the replies and i hope its not the head gasket as I've only just brought it, the car has been standing for about three years before i brought it so i was thinking this could be the reason as there's no sign of gunk in the oil or filler cap and it stays at the normal temperature all the time and I've driven it a good 300 miles since buying it last week. I'm going to get it to a tuner soon as and get everything checked out properly.

thanks again.

Hi

If your scoob was stood up for such a long time without running or hardly running... I strongly advise you to have all the fluids changed asap... engine coolant flush, oil flush, hydraulic fluids, diffs etc etc

Coolant is made up of three main components

A water softener/conditioner
Anti Freeze (alcohol)
Water

Each one of the above needs to do its bit... Water to carry away the heat, Anti Freeze to stop ice crystals forming and conditioner to make your hair look nice.... ok only joking the conditioner reduces the acidity of the water it inhibits corrosion and helps to keep your water pump and radiator from clogging up with gunge... Its important to have the right mix of fresh coolant flowing and not sitting... the mix degrades over time so needs replacing at the correct service intervals, even if the engine has not run, in fact sitting is worse!

Get those fluids changed!

Moto man says... "if you look after the car... the car will look after you!"

Good luck hope nothing else has happened.... would be good idea to change your hoses as well as they may have started to rot

Hope this helps... now taking my Anorak off again

Nobby

What a GEEK!

Did have a chuckle at the Moto (motto?) man bit.

Very good info though and excellent advice. Agree 100 %. Get those fluids changed asap if it's stood that long.

- Engine oil
- coolant
- Gearbox oil
- Diff oil
- Brake fluid
- clutch fluid

Will be pricey but a lot cheaper than any potential damage caused by leaving the old fluids in there.

Re: brown coolant

Hi.

The best coolant to use is a ethylean-glycol basis coolant 50/50 mix. Fill the oil in the hole where the gearbox dipstick is.
