Volvo 850 heater core replacement 2

Post by **Pauloil** » 11 Sep 2011, 07:48

you can bypass with some 5/8" hose from car parts place, or just move the longer heater hose over if you plan to replace it later. don't know how much amperage cig lighter is able to handle as the wires to it are fairly small

Coolant on the floor is definitely messy. I sympathize. If you do this again, take a heavy gauge plastic bag (I use the grocery bags from Aldi). Roll down the top a little (like opposite of rolling up your pant cuff) and pull it up under and around the bottom of your core housing. With the condensor pipe out pulled out, you can get the rim of the bag pretty much under the housing but will still have enough room to take screws out. Drop the bottom of the bag by the accelerator, behind the brake pedal. I partially drained my cooling system, but still had a least a pint leak from the core when I did mine and was very glad I had this "catchment". The bag will eventually start to leak from the alcohol but will hold long enough to get the trapped coolant into a bucket.

A heavy duty trash bag might work, but you don't want a real big one, just something large enough to surround the base of the core housing and leave some work space.

Taking it out wasn't the problem. My mess came when the core blew and the car was nursed home.

Precopster mentioned at the beginning of this thread that he had replaced a core without doing the coupling & still had leaks. If the O rings in the coupling are old & you pull the pipes out & push them back in I imagine you might have some problems. Apparently there is no o ring kit for the coupling, so it is advisable to change the coupling when you change the core. I paid about $35 for mine from FCP so it wasn't too much extra to make sure those O rings were new as well. I'd do the bypass until I could do the whole job at once. I ran around with mine bypassed for 6 months with no issues except that I had to rug up a bit, & the heated seats helped as well

All the best, I understand funds being tight for sure!

Bypass is done. Carpet and most of the padding are cleaned and dry. The padding up front still needs some work.

Just to clarify; my leaks were on the engine side because my engine side seals had been damaged during removal so I used the URO engine side seals ........big mistake.

If the OEM seals had come out in one piece it just may have worked.

Was looking at IPD's site last night and noticed that they are now selling red SILICON seals for those who buy the Behr core. This is a BONUS because the Behr heater core doesn't come with seals and this means you can avoid the dealerships AND the nasty GREEN aftermarket ones.

Thanks precopster, I still have those green ones & the SLOW drip is still there no matter what i do. Haven't had time to look very far for the OEM seals. I'll try the silicon seals. I can't understand why Behr would not put 2 decent O rings in the kit - it's a must to replace the old ones surely!

G,day Precopster & Taxidad...FCP alert for those of us in RHD land... don't buy the pollen filters, they don't fit.
It only cost about $10 but seems they are a different size in USA cars. My pollen filter(Volvo part # 9134750) is 275 x 170 x 24mm but the FCP filter is 260 x 170 x 32mm, because I'm a tightarse and have plenty of time I might pull the guts out of it and make it fit in the old filter frame-work as I was quoted $35-45 for a replacement filter here in Adelaide.

Hmm strange I bought the pollen filter from FCP in January part number 9171296 for $11.95 (just looked it up) and it fitted directly into a used V70 retainer bought here in Oz. Do you have a V70 retainer or is yours the correct 850 retainer (is there a difference?)

Yep, thats the same one I got but according to FCP it fits an 850 as well but not mine. When I purchased the car back in 2001 I bought the holder & filter from my local Volvo Australia spare parts counter so I assume it's a genuine Volvo holder, has a part number 9134750 stamped on it.
