Default Replacing heater matrix

Anyone know how easy this is to replace? I've watched Robert DIY do it on YouTube and and it looks pretty easy, although in practice might be another matter.

Anyone know a good place to source one from?

Final question, am I safe to go on a long(ish) journey tomorrow? I am due to travel from Leeds to Manchester, so a round trip of about 80 miles. I have lost a bit of coolant in the reservoir.

Cheers.

It's a couple of years since I did it but it was really easy, IIRC being RHD made it even easier than the videos. The worst bit is trying to catch the coolant that escapes when you remove the pipes or, more likely, trying to clean it out of the footwell.

You should be safe to drive as far as you want, provided your low coolant light works and you keep an eye on it.

I don't know the best place to buy one. I got one from ECP that claimed to be a Behr (which is supposed to be the good one), but I don't think it gave as much heat as the old one.

That is exactly why i suggested volvo , an extremely high capacity heater core . you get what you pay for ..

The new Volvo one I installed failed just after 12 months. However the aftermarket one (hella) from memory has been fine for over 8 years and was half the price of a discounted Volvo one. As others have said get the two o rings as well.

many thanks all, for the replies. I will give it a go myself. I rang a Volvo specialist this afternoon and he quoted over £600, which is more I paid for the car.

I did come across this, but not sure what brand it is: https://www.partsforvolvosonline.com...oducts_id=3634

on my long(ish) trip tomorrow, will it help if I keep the cabin temperature dials down to cool? Presumably that means no hot coolant running round the matrix, or have I misunderstood how it works.

Your Volvo specialist is having a laugh at £600.
2 hours work max
The matrix is on all the time in these so heater setting has no effect on coolant loss.

It's an easy enough job. As mentioned above you will have quite a bit of coolant making its way into the passenger footwell. I purchased a Behr branded heater matrix which was identical to the original one that came out of the car. It was a quarter of the price of the Volvo part and has been working perfectly for over 1000 miles since fitment. There's no difference in heat output from what I can tell. When installing the two new o-rings I would recommend applying some silicone grease to stop them from rolling as you slide them over the aluminium pipes.

30 min job once you get your head round it.

The original ones were clamped at the ends, Ford replaced the proper blue box parts for their own ****ty cleap version. Not ideal for us in the long term

There will be spillage.
