Want to encourage you guys and gals to change out your old coolant expansion tanks. They can crack under pressure and if your "low coolant level" sensor is NOT working it can cost you a motor. Cars overheat real fast without much of a warning when they loose coolant.

I was as at the jy the other day and decided to snag a coolant reservior. Mine looked brown and this one was nice and clear. Pulled mine yesterday and as I was pulling it I realized that my LOW COOLANT LIGHT was not working. I knew the coolant was low (because I'm always under the hood) but didn't realize the LOW LEVEL WARNING was not working, so I double checked it and sure nuf, no light. Changed out the tank and was surprised how brittle the old one was. The tip of the overfill spout actually broke off in the hose that connected to it and the cap (green) was cracked on the top. All in all, I'd say it was past due the change. The $5 part was well worth it.

 

What causes the service engine light to come one? Or is it just a reminder that comes up after a certain amount of miles?

And also in regards to the sport button. Does sport mode just change the transmission shifting patterns? Or does it also change something in regards to the engine in that mode as well?

 

Question on the brake fluid: You say you use DOT 4, the manual says to use DOT 4+ which seems to only be available through the dealership. You have success with the 4?

 

Great information. Glad I clicked on.

In reference to the A/C evaporator,is their anything one can do to help prolong the life of that component except using it?

 

There is a ton of useful information in this forum. You guys kept coming up in my Bing searches about various issues, so I decided to join and learn more from you. Great info here!!

 

Hi there *thread bump*

I have been having issues for months with coolant leaks. I replaced my radiator and heater core about 10 days ago and coolant is back leaking into the interior of my car. What else could this be?

94 Volvo 850.

 

Firewall coupling.

 

Anyone know what's this?

I bought my first Volvo last January and still not sure what this goes to. And yes, you see the mileage is 324,000+. The speedometer stopped working; I just use my GPS. It's in a great shape than the average vehicles :P

Also, I have a coolant leaking. I have a floor wet all the time since I got it and I know it's a heater core. I only need o-rings for the heater core? Previous owner told me they replaced the heater core, but I don't think they replace o-rings and whatever else. Let me know, thanks!

 

Picked my first Volvo last year. After a slew of american cars, I am impressed with the german engineering. I went on this forum first part of the year looking for fuel pump tips. Read a post about checking the relay prior to replacing the pump, and I am glad I did. The paper clip trick did the job. Got the relay for $53 from the dealer vs $320 for the pump module. In both cases, relay and pump mod, the swap outs would have been easy.
Picked up front control arms/ball joints from FCP for $36 ea. The ball joints alone, from the dealer were $84 ea. Put them on yesterday in less than 2 hours. Good parts/good prices. I will shop there again. Noticed that the passenger CV joint is original and just started making noise. I know what my next project will be!

 

Volvo is Swedish, not German. They do use a lot of German parts though

 

Thinking of buying 04 S80 t6 but has 105000 mls. Buying for $2666.66 but don't want to dump lots of money into it. How can I visually inspect timing belt? What's going rate for timing belt replacement?

 

Visually inspect a receipt for it or have it replaced. Call the dealer, they will give you the price.

 

THANK YOU JPN! I have had my 850 sedan for over a year now, and have been needing a list like this. General maintenance and common small problems with the fix! AWESOME JOB!!! (I'm a woman with not much knowledge of fixing my own cars. This '95 sedan is my first guinea pig) Many issues that I was having with the 850 have been answered by reading your list! Thanks! Great job!

 

My 850 glt 1993 reverse doesn't engage.
Can someone give me a suggestion?
