I tried searching for a few minutes first, but couldn't find anything...<br>Do you have to use Volvo Coolant, like the manual says, or is it the normal crap where they try to get you to buy their expensive stuff when it doesn't really matter.

Re: do I have to use Volvo Coolant? (cY2k)

I'd say the latter. I'm using regular coolant from my friendly neigbourghood autopart store, works just fine <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Normal "crap" is not okay....make sure what you get is ethylne glycol and says on the container that it is safe for aluminum radiators. Volvo engines for the most part are aluminum too so you don't want to harm them. Avoid the orange stuff...use the green florescent colored stuf...you don't have to use Volvo's special coolant.

Yeah, good correction MIJ. <br>Sorry, I just assumed that "crap" is not actually crap, per se, but rather "common brand coolant", obviously it has to be suitable for alum rads. <br>Note to myself: Gotta finally learn that "assume" don't work, never assume nothin' <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: do I have to use Volvo Coolant? (cY2k)

Well, look at it this way - how often are you going to replace the fluid? I paid I think $20 per gallon, and you only need one - every 2 years. What's $20 over 2 years in your car maintainence compared to the price of gas, oil changes, etc!<p>My guess is that generic stuff will "work" as in cool the engine, but may cause more corrosion in the long run due to incompatible chemistry... and it is more expensive to replace rads, water pumps etc than to fork out $20 for Volvo coolant.

Agree....although other coolant of the right contents will work fine, what is forking out a few more $$ and be absolutely sure?

Re: (cY2k)

Well, it depends...<br>It's normal for the coolant to evaporate with time, so if you have topped it up a long while ago and see that now it's a little on the low side - then it's expected. On the contrary -if you filled it yesterday and today need to put some more - then you have yourself a problem. But in that case you'd have a pool of coolant underneath your car, or white (I believe) smoke coming out of your pipe, or some other indications of things going bad

Re: (cY2k)

Well do you see a drip under your car where it is parked? The water pumps tend to start leaking after a time. I'd get it replaced when you get the timing belt/tensioner done next - easy to get at that way <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: do I have to use Volvo Coolant? (cY2k)

Interesting story..... I brought my S70 into the local Volvo dealer about 3 years ago and amongst other work asked for a coolant flush & fill. I was sitting in the waiting room about 5 minutes when the service manager pops his head in and asks to speak with me. He told me that Volvo has no recommended coolant replacement interval and that the coolant never has to be replaced on my car! This floored me as I had never heard such nonsense before. Since I have never heard of 'permanent' anti-freeze I had them do the flush and fill anyway. After leaving the dealer I noted that the coolant low reservoir level idiot light was coming on so I brought it back. A tech came out to top it off and he wasn't filling it with 'Volvo' coolant (wish I had written the brand down!). So if the dealer really charges $20 a gallon for anti-freeze maybe it is special stuff......

Re: (cY2k)

One other consideration, and it's not good. You could also find it in the engine oil if you have a bad head gasket. That's the worse case.

It matters

I'm having the same problem, but I've found that it does matter. My problem is the volvo dealer said use "silicate free" coolant. (some mechanics are actually dangerous, maybe this one is right, ....or not) All the specs for volvo and info say that silicates are needed especially in turbos. Notice how hot your turbo runs when you touch the hood. You could fry an egg and the temp gauge is right in the middle. I heard the silicates are good for hotter parts where there may be damage from bubbling. I want to use Pentofrost which is made for Euro autos and is said to be just as good or better than Volvo brand. It's Sunday and I can't get genuine Volvo and today is my window of opportunity for getting this done.
The aluminum engine is just one problem. I'm reading that the euro brands have no phosphates and are more eco friendly. Don't know if that matters to your engine: worse or the same.

It matters which coolant you use.

A alternative is Pentosin NF. It's the same color and same properties of the genuine coolant. It's odd that it comes in a 1.5 liter container. This is a concentrate and not a premix. I use this one to top off both my Volvos.

I've run standard prestone green for 7 years and 100k miles in my V70 and had zero problems. I also flush and replace it every 2-3 years.

I run Zerex G-05 in my C70 because I got it at 39k miles and I wanted to be sure I was using recommended stuff. Also flush and replace every 2-3 years.

I run the Volvo stuff. $20 for a gallon versus $10 for walmart stuff... What's an extra $10 every couple of years for the certainty you're running the right stuff?

YES and absolutely.
Coolant systems do not go low unless you have a leak ....or MUCH worse!

Diagnose and find out now why, not next month

You too, you have a leak. Find it and fix it before you get into some real trouble

Believe it or not, this actually happened to me yesterday. Turns out my cap was cracked....

So, believe it or not, I actually:

1. Went to the DEALER
2. Bought a new CAP (like $36)
3. Also bought new Volvo BLUE concentrated coolant. Refilled 50/50 that and water (I had purified on hand so I used that.)

I didn't go and get the wrong antifreeze. I think that calls for celebration.

Coolant cost $28.

I put on the oil cap gasket, too.

This a good possibility if you can't find a visible, or "external," leak, suck as hole in a hose or, in my case, cap had a crack, allowing it to escape under pressure and not hold full pressure.

Some pics of the milkshake or mustard oil when that happens, it can look lighter or darker depending on how bad the mixing is, and its never good because coolant (at least ethylene glycol - green - Volvo coolant is different) deprives lubrication and kills bearings:
