Quicky anti-freeze question?

Don't mix colours, top up with the same as it currently has in it. If you're changing it apparently blue is the correct one to use. It's also the cheapest [;)]
 
Hi :)

There are 2 types of antifreeze...and colour makes no difference..

1..Methanol based....cheap but with one huge disadvantage..it evaporates when hot...lol..DONT use it....

2..Ethylene Glycol based....good quality antifreeze....use a 50% antifreeze and 50% water solution...if you havent got an antifreeze hydrometer...easiest way is to drain ALL your antifreeze and water mix......throw it away...then put in 50% a/f (example if cooling system holds 8 ltrs, then put in 4 ltrs of neat antifreeze) then top up with water....make sure no air locks afterwards by getting engine to temperature then letting go cold before retopping up with water....

Do NOT open cooling cap when engine is hot....you will get a face full of boiling coolant mix!!

All the best Brett :)
 
Any is fine but make sure that it's phosphate free. Most are these days but some very cheap ones are not.
 
Thanks Brett,
I was thinking Glycol based but got a little confused last time I went in the motorfactors because they had a green one and a red one and one of them had organic salts or some such like, I also had and currently have blue fluid but I will be draining it all out because me thermostat is worn. Typical problem, car warms up OK drive at 60 or 70 but when slowing down for a roundabout the needle drops down then slowly picks up again after accelarating. I wouldn't mind but I am using the car at the moment to commute (fancied a change and of course the Saab is on 3 wheels at the mo) and she is drinking fuel like a 928!,,,,sorry I couldn't resist.

One last question, what is the current practice for used coolant? I can suck mine out with me fluid extractor but I can't recall a waste bin for this type of fluid at the dump.

Hi :)

There probably is a tank at the tip for this but most people just use the drain to be honest...

As i said...make sure the container says Ethylene Glycol on it...not Methanol....then drain yours......bottom hose is easiest if no drain plug....you can start engine for a few SECONDS not minutes to pump out any excess...make sure coolant cap is OFF while draining or it wont drain properly...

Then add 50% of cooling system capacity then top up with water...etc....see above :)

Any problems as you are in Dorset and I am in Bournemouth...ring me (email in my sig for number) and I will help you...I have an antifreeze hydrometer as well in my Snap-on tools.... :)

All the best Brett :)

P.S Mine doesnt drink fuel lol..it swallows it in bulk :)
 
don't forget folks antifreeze is always lethal to animals . Don't just pour it on the floor or leave it in an open can or container. its sweet and tasty to dogs and cats and children there is no cure or antidote if injested in large enough quantitiesi it can be lethal
