Re: 1997 Volvo 850 GLT Coolant Question

Update: I picked up the o-ring set from Harbor Freight. They didn't have one that was a close enough size and they seemed lighter weight than originals. I could not bring myself to install the HF o-rings so I washed off the original ones, played with them a bit to see if they'd fall apart, then rein...

Re: 1997 Volvo 850 GLT Coolant Question

You can also reuse your orings and run water only for a few weeks if you promise to drive at 55 and be aware Then swap them out when you and I do that AC evap core After all the 'you must install new o-rings' warnings from everyone I'm terrified to 'reuse' o-rings. :) Are the HF o-rings good? I'm n...

Re: 1997 Volvo 850 GLT Coolant Question

I'll stop by HF tomorrow. HF HNBR kit has eighteen sizes. I'm looking around web for o-ring size specification for heater core o-rings. I expect snug but not too tight is good enough. Or is it better to use closest fit to o-ring slot in heater core inlet/outlet? I believe seal occurs when heater cor...

Re: Coolant Leak and System Issues [1997 Volvo 850 GLT]

I noticed this old thread and see that I never brought it to closure. The leaking hose I had to replace was about five inches long and located in back of engine on passenger side (As I see Sommerfedt also identified above). This appears to feed turbo. The other metal line runs into block. This was a...

Re: 1997 Volvo 850 GLT Coolant Question

My new heater core arrived. Unfortunately after looking at the Nissens heater core page (with o-rings) it stuck in my head that the o-rings naturally come with the heater core. Not with the more expensive Behr core. Pains me to pay FCP more for shipping than the o-rings actually cost but may need to...

Re: 1997 Volvo 850 GLT Coolant Question

Thanks. I bet they redesigned/improved the clips in conjunction with the new coupler/junction box. I'm planning to order the Behr heater core and the complete junction box (with o-rings for four connections instead of one per o-ring kit). I'll use the o-rings and have the junction box and extra clip...

Re: 1997 Volvo 850 GLT Coolant Question

Those hoses are really high quality and rarely fail. Replace every oring on both the bulkhead and the heater core connect with genuine Volvo parts and you should be fine. https://www.fcpeuro.com/products/volvo-heater-hose-o-ring-kit-850-c70-s70-v70-3545662oe I initially took your instructions above...

Re: 1997 Volvo 850 GLT Coolant Question

Houston, we have a problem: IMG_0166.JPG I'm pretty sure I know where all of the coolant I've been adding is ending up: IMG_0175.JPG I noticed the coolant flowing back along the top of the center console hump. The back seat floors were flooded with coolant. The front driver and passenger floors not ...

Re: 1997 Volvo 850 GLT Coolant Question

My old heater core just doesn't want to come out. The rubber condensation drain is in a bad spot. Doesn't just rotate nicely like in the three videos I watched. Then again I don't like forcing things so I'm a little on the cautious side. I'll have an update once I manage to get it out and take a look.

Re: 1997 Volvo 850 GLT Coolant Question

I haven't opened things up yet as I'm currently reading up and watching videos on heater core replacement. Robert's videos give me confidence to consider fixing this myself. Sadly, I think I've watched his heater core video before just for fun, like many of his other videos. My main concern is scope...
