Hi guys,
I'm a new poster to the 850 blogs, I own 240's and a 940 and have for years-do all my own work on them and find them great to work on. Just wondering about the 97 850 model- I know it takes the same oil filter as my other b230 engines but how about the acessability of the filter- easy to reach? How about the drain plug? Also, this is a friend that's buying this 850-it's got 117,000 on it. Any outstanding issues that he should know about that might be in the future? I know almost nothing about this engine and would appreciate any info. ya'll could give.
Thanks.

Oil filter access much better than the early Volvos. Check timing belt replacement interval. Due every 70K miles. Engine front motor mount goes bad. AC evaps can leak. Check tranny fluid for burning. Check CV joint boots, brakes, tires, etc.

Welcome to the FWD/AWD forum!

Oil change on an 850 is just as easy, if not easier, than on a B230 engine. I've it done without jacking the front end up but it's easier if it's up a few inches. The filter is accessed from below, located at the right side of the oil pan - super easy. The only hassle is that once the seal is broken during removal, it is inevitable that some oil runs down the side of the filter onto your hands.

Buying a used 850: Service history is key. Abused cars are to be avoided. Just like a B230 it is imperative that the PCV/flame trap system is kept clear with frequent maintenance. otherwise it will get gummed up causing oil seals to fail. It is an interference engine so make sure the the timing belt has been changed in the last 70K miles. Check for the correct color of the tranny fluid if an auto. Check that the AC works, it is common for the evaporator to fail. Fixing it is like replacing a heater fan in a 240 - a big job. ABS controllers are known to fail. Check that the ABS and or TRACS lights come on when the key is turned and don't stay on.
