Expansion Tank
The expansion tank had a dribble of coolant around its edges, so I decided to replace it, just in case it got worse or blew.
So bought one of these: http://www.ebay.co.uk/itm/Volvo-S70-...gAAOxyLNpSEzzd I fitted it and topped the fluid up, then the "Coolant Low" message came up. I thought I'd damaged the sensor that fits in the bottom of the tank, so got a new one from Volvo, fitted it but still the same message. I contacted the supplier and let them know about the problem and they are sending a replacement tank, I figure it must be a faulty float switch on the new tank. Has anyone had this happen before?

Minor coolant losses are often solved by simply flipping the cap seal.
Worth trying if you've still got the old tank on. I'd be surprised if many have needed to replace the tank because everything in a Volvo cooling system is pretty reliable.

Already replaced the tank, just trying to get rid of the "Coolant Low" message now.

The newer coolant tank arrived so fitted it today and it made no difference.
It's had a new sensor fitted too so can't figure out why the message won't clear. I still have the "Coolant Low" warning. Anybody got any ideas what might be the problem?

Assuming that the only point where coolant level is measured is in the expansion bottle, the issue must relate to either the sensor, the wiring, or if fitted, the fuse. Considering the new bottle came with a new sensor, the sensor is not likely to be the problem (although stranger things have happened). I'd have a real good look at the wiring going to the sensor, and trace it back as far as possible to make sure there aren't any breaks or fraying etc. Not sure if it matters, but are you using the right mix of coolant and antifreeze?

Thanks for your input Dancake.
The new bottle did not come with a sensor fitted, I don't think they're supplied with the sensor in. Just been out and linked the two sockets in the connector for the sensor and the warning went out. So the wiring should be good. It is a new sensor from Volvo but the previous one was working okay before I fitted the previous new tank. That is what led me to believe the new tank was at fault. They sent me another tank and I fitted it today but still no change. Now I'm wandering whether the tanks have a manufacturing defect and although the float works it is not closing the sensor.

The new tank quite possibly is the problem as its un-branded...poor QC?
Are you sure your old tank was actually leaking, good chance it was a hose connection and by removing and fitting the hose it is now better sealed. Much better to now put your money into a genuine tank from a breaker. Try 'parts gateway' or your local. |

Just for info, The seller of the coolant tanks on Ebay agreed with my findings and gave me a total refund and apologized for the trouble caused.
They did not want the suspect tanks returning for testing either..Odd? So I ordered one from the stealer, only £3 more as it happens at nearly £30, fitted it and all is back to normal. I wish I'd done that in the first place instead of trying to skimp. Think I'll be giving Ebay a rest from now on

Had a 'similar' issue doing a favour for a friend, it was a duf heater blower fan in a Transit van, bought a cheapy new one from some outfit called TransitPartsUK and in the post appeared a shoddy far eastern copy that worked for all off a month before it started making squealing noises, it still works but now i have to strip half the dash to get back into it to see whats up!
Some cheap stuff may be up to it but some items just call for genuine (spit), of that i have no doubt, (never did). Glad your all ticketyboo again. |
