Diagram of installation process alternator 1998 Volvo S70
I don't have a diagram. Here are the steps.
1) disconnect negative battery wire..
2) remove serpentine belt
3) remove upper heater hose and thermostat housing; leave thermostat in place
4) remove plate from in front of the power steering pump, the lower bolt is one of three of the alternator bolts.
5) remove all 5 bolts from the PS pump bracket - 2 are by the thermostat housing. Remove the bracket.
6) move the PS pump off to the side out of your way.
7) Remove the long bolt from the alternator you can now see. There is one more alternator bolt at the top which will allow you to remove the idler pulley bracket with the serpentine tensioner. This idler bracket and the tensioner bracket are sizeable, so you have to understand the volume of stuff you are removing.
8) Unhook the alternator wire and with some patience, if you have any left, you can squeeze the alternator out.
This procedure assumes you have the ability to do the serpentine belt removal and refitting, and you will need 12mm sockets/wrenches to do the rest. The t-stat housing uses the torx head screws, so you need that as well.
I changed lower hose from expansion tank - still
the temp gauge should be reading around the 1/2 way mark and the pressure is controlled by the radiator cap. Check the catalogue at you local spares shop and the cap recommended will hold the correct pressure for your car.
Adjust headlights
For left right you use and allen wrench on top of the light housing. Up and down is a knob on the back of the housing.
Does an exact fit used ECU need to be reprogrammed on my 1998 s70 volvo
You can try a Hard Reboot, remove the battery cables from the battery, wait 20 minutes then make contact with the + an - cables together for at least 10 seconds. Normally you would want to run a diagnostic on the new computer if it cam out of another car just to erase the codes from the other car.
Volvo s70, 1998, heater not blowing hot air
Are you getting coolant flow through the heater core? These cars have common problems with heater cores but they are easy to replace. IPD has a Video on U-Tube with step by step instructions. Also if you are in very cold weather have you checked your anti-freeze? I saw a Toyota last year freeze completely because of no anti-freeze. It took days to thaw out the heater core and they were lucky that the ice did not blow it apart. It took me hours of starting it and running up to a low temp and shutting it down to get it drivable.
My car is needing antifreeze about every two days
Have your Cooling System pressure checked. Also check your oil and anti-freeze. If the oil is milky or the anti-freeze is oily you have a blown head gasket. Watch for white smoke (Steam) coming out of the tail pipe after it is warmed up. If you have white coming out that is coolant, black is fuel and blue is oil. After the pressure test if there are no leaks detected in the hoses then get a compression test to see which cylinder is leaking.
