Replacing freeze plugs is easy. Getting access to the one leaking may not be. Freeze plugs drive into their holes and you need access to do it. There are some aftermarket freeze plugs that can be installed and expanded into place with a wrench. But you still have to get to it. Depending on where it is, it may be easy to reach, or very difficult, such as on the rear of the engine where you must either remove the engine or transmission to gain access.

fill with water and turn motor over get someone at rear to check if water is comeing out exhaust, or remove overflow cap and turn motor over to see if air bubbles are bubbling the water, if yes, get your check book out...!!

I would look at all the fuse .You only need one thats got a fine airline crack .And all eath points in the engine bay .

I tink that you should chang the heater radiator

Get some cans of brake clean and spray it all off.wipe with rags respray and so on till clean.run it or just get under it after you add oil and look for thr leak. It could be up as high as the valve cover.

Cannot place where it is on the vehicle ,sorry iam a general mechanic not a dealer fitter some cars are under the inner wing so its a wheel off and remove the plastic inner wing ,some cars are behind the front bumper so its a bumper off job other have the bottle under the engine bay so relative easy to change .You will just have to have a look and then decide if its a garage job or a home DIY .

Sounds like your rotors are warped,, if you installed new disc brake pads and DID NOT turn the rotors.. there is a good chance they DO need turning...

Hello Joan, The climate controls on your Volvo are all electronic at the control end, but likely have little vacuum motors to control the opening and closing of heater valves and air directional flaps in the innards of the dashboard. With the "mature" nature of your vehicle, it is sometimes a cracked vacuum hose or that the rubber end is getting a little hard and now leaking at the nipple where it is plugging into the vacuum valve. IF this is the issue, you MAY be able to here a hissing noise immediately after turning off the engine. Crawl down and get your head (ears) right under the dash. There may be a cardboard/plastic cover plate on the underside of the dash that you have to remove to get access. But from the symptoms that you describe in your post, "Temperature dial has lost it's clicks"... I SUSPECT that the contacts on the control module may be totally worn out for both the direction of flow and the temperature control. Modules are available on eBay/Amazon (usually used) and it should be quite straight forward on how to remove / replace. The link below provides both links to purchase the control and also some YouTubes on how to replace it. Hey... do you have a Pick-n-Pull or similar self-serve auto-wrecker near by? Often you can see what vehicles they have on their lot. It appears that s70 v70 and c 70 Volvos from 1998-2000 all have the same control unit. I've also included the part number in one of the photos... do a search for that and you may find more hits. I hope this helps you Joan! 1998 Volvo S70 2 0 Google Search

hi black smoke is not good, and you say the water level is going down. im sorry to inform you may have a blown head gasket. rough running engine lite, if you have just bought the vehicle i would recommend taking it back to were you bought the vehicle.

I hear that, about parts not necessary. Quite a discrepancy among those mechanics. All I could say is to find a mechanic who is familiar with Volvos. My suggestion,. without knowing what codes were given, is that possibly your throttle body needs cleaning. This is where the air enters the engine, and carbon or fuel deposits tends to build up there. It can get black and dirty over time, and cause problems like rough idle or hesitation. But anyway, find a smart and honest mechanic-not always easy, but they should be better than guessing after getting the codes.

How does it "sound like it's going bad"? It's aftermarket, and it isn't the same as OEM. It won't sound the same either. That doesn't mean it's bad. They might have left a gasket loose, making an unusual and loud sound.

Its an antifreeze leak inside the cabin look for actuators or holes in any that carries vacuum or antifreeze also leaks on the floor something is leaking

possible bad coil...download ecm codes to see

You need a locksmith with the correct equipment. There is no "simple code" otherwise thieves would exploit it. Be sure and have the title available as the locksmith doesn't know if you stole the car either. Do call many places for prices as I just found out with getting a second key made for my 99 Ranger, prices ranged from $120 to $220!

U get that from the dealer.

Try make a OBD readout. Perhaps there are a troublecode stored in the system. The relay to operate the gasolie pump in the tank can be defective so the solder is getting hot and loses contact.
