you will need a hacksaw blade to cut the retaining loop. pull the door as far out as you can and cut the loop taking care with the dash and door vinyl. I protected mine with duct tape that I removed right away... You will need to replace both the loop and the door latch. $75 for both

The latch is just above the rear license plate. Reach your hand up in there and pull the handle towards you. Of course, all doors have to be unlocked for it to operate. If, by chance, you meant the front hood of the car, there's a red pull-lever near the driver's left foot that, when pulled, releases the hood latch. Then, you need to go to the front of the car and find a grey, hooked piece of plastic sticking just barely out through the grill (above the Volvo logo). Get your finger underneath that and pull towards you. It'll come out about a centimeter and, while you have it pulled out, lift up the hood.

you will only find a hi pressure side

The cost to replace the rear brakes on a Volvo station wagon typically ranges from $300 to $600, depending on the model and location. This estimate includes parts such as brake pads and rotors, as well as labor costs. Prices may vary based on whether you choose OEM or aftermarket parts and the specific service shop rates. Always check with local mechanics for a more accurate quote.

The oil pan from a Volvo 850 turbo is generally not the same as the one from a non-turbo Volvo 850. The turbo models often have specific design features to accommodate the turbocharger and may have different oil capacity or baffle designs. Therefore, it's important to use the correct oil pan specific to the model and engine type for optimal performance and compatibility.

The windscreen wiper relay for the Volvo 850 is typically located in the relay and fuse box, which is found in the engine compartment or under the dashboard on the driver's side. To pinpoint the exact location, refer to the vehicle's owner's manual, as it provides a diagram of the fuse and relay layout. If you need to replace it, ensure the vehicle is off and consult the manual for the correct relay specification.

The Volvo 850 typically uses a 12-volt battery with a capacity ranging from about 70 to 100 amp-hours, depending on the specific model and year. The battery is designed to provide sufficient power for starting the engine and running electrical systems. Always check the owner’s manual or specifications for the exact battery requirements for your specific vehicle.

The symptoms you're experiencing with your 1993 Volvo 850 could be indicative of several issues, such as a failing coolant temperature sensor, a problem with the fuel system, or a malfunctioning idle air control valve. It's also possible that there could be an electrical issue, such as a loose connection or a failing alternator affecting the engine's performance. To diagnose the problem accurately, it would be best to check for any diagnostic trouble codes (DTCs) and inspect the related components. If you're not comfortable troubleshooting it yourself, consider consulting a mechanic who specializes in Volvos.
