Volvo 850 Radiator
Volvo 850 Radiator Troubleshooting Tips
Your Volvo 850 radiator is the main reason why your car has not blown up yet. It constantly deals with a ton of pressure and heat, thus issues concerning this part are not that uncommon. The best way to prevent any radiator trouble is by regular inspection and diagnosis. To help you with that, here is a simple troubleshooting guide, listing down all common problems, their causes, and some fixes:
Whenever your car starts to overheat, one of the most common causes is the radiator going bad. First thing to check is the coolant level. Take a look inside and see if the coolant level is up to standard. If not, then add the necessary amount of coolant.
Another area to check is the cap area. Put your hand over it and shake it for a bit. There should be tightness felt when doing so. If it is loose, then this might cause the coolant to spill, wasting all those precious fluids. Make sure that the cap is screwed tightly. If it is too loose, however, simply replace that specific part.
Lastly, you need to test whether your thermostat is functioning or not. Place your hand on the lower radiator hose and let your engine heat up for a bit. If you do not feel anything while the car is running hot, then this means that the thermostat is broken and must be replaced.
If you notice any leaks from under your vehicle, then you should first see if there are any cracks coming from the radiator. Take out your flashlight and have a good look inside. Notice if there are any fluid movements even in idle. If there are, then fix the leak with sealants, which could be bought at any local car store.
If there are no problems in the radiator but it is still leaking, then consider the hoses. When inspecting them, see if there are any signs of rot, or whether they have turned brittle. In these cases, it is best to just replace the entire hose completely. However, if the hose is just loose, then just reattach them properly.
