Hi DIY's,

So I have an 02 C70 that has had a very slow coolant leak for a while now but I haven't been able to discover from where, but recently the car has started putting out a coolant smell when running the windshield defrosters. Also, the windshield is constantly fogging. In looking around on this site and others, I've heard people describe this as a heater core issue along with coolant soaked carpets. As far as I can tell, I don't have coolant on my carpet but the smell has been intensifying. I have also read some mention of bad O rings associated with the heater core.

Questions - Has anyone else had this problem and been able to diagnose/fix it? I have found instructions for other model volvos for replacing the heater core, but not for the C70. Is the procedure basically the same? Does anyone have a link for replacing the core for the 02 C70 (if that is indeed my problem)?

Any and all help is appreciated!

Thanks.

Just follow the write ups. Only thing different will be to unscrew the Dolby processor, gl.

Hey MKC70,

Not really sure what the Dolby processor is. Is it a part of the stereo that might be in my way? Also, I have just finished clearing the way of the carpet and other panels to get to the heater core, and yes there was antifreeze beneath the carpets. Is there any way to tell if it is the O rings or the heater core that are causing the problem? I can't exactly tell where the leak is coming from, but there is definitely antifreeze dripping from the bottom of the attachments coming from the firewall to the heater core encasement.

Thanks,

MT

I do also have a fogging issue on my windscreen especially during rainy days. Usually, De-frost mode is incapable to get rid of fog.

p.s There is no leak and smell as mentioned above.

Please help. Thanks.
