Coolant leaking on 1991 Volvo 740 Turbo Wagon

Hey, my 91 volvo recently overheated going up a pretty steep hill the other day. I let it cool then filled it with coolant, but now there is a serious steady leak coming from the front, passenger side of the engine. I initially thought that is was just the seal that broke on the hose but it looks like there is a leak just behind where the hose connects to what I think is the waterpump. It is directly in front of where the fan is connected and the coolant is leaking through there as well.

Wondering if I am looking at the waterpump and what kind of repair I should be looking at, if I can do it myself or if it is in for the long haul.
Thanks

Yes, probably water pump, but easy to do yourself. Change thermostat now as well.

There is a pipe that connects to the rear of the waterpump right where you say it is leaking. I would guess the seal is leaking. Since you have to remove the pump to replace the seal, you should replace the waterpump.

These engines commonly blow the headgasket when overheated, and commonly overheat and leak coolant when the headgasket is blown. So it may be hard to say what came first, but either way you will need to determine if the headgasket is OK before you make any repairs.

Good Luck,

My 1991 volvo 740 turbo temperature gauge shows overheating?


Simplest most likely cause is the thermostat is stuck closed.

On the far right warning light--SRS--is what is showing--never seen it before--'91 740 turbo station wagon--thank you for your time--louise


This light is refering to the Safety Restraint Sysytem. This includes such items as seat belts, airbags, modules, etc.. This needs to be serviced by a trusted technician who is versed in SRS systems as they can be dangerous when not serviced properly. Is there anything else not working like the horn?

'90 Volvo 740 2.3l turbo water pump install instructons needed


Go to an auto supply store like PEP boys or Advance Auto, etc., and buy a Haynes Repair Manual for the 740. You may be able to consult one at your local library for free. Even if it doesn't cover your model year, the replacement instructions are pretty much the same for all years. in fact even a 240 Volvo manual would be essentially the same. Pay particular attention to the installation instructions....you have to slide the pump on, and then rotate it a few degrees clockwise to make the upper o-ring seal. Good luck!

Can you lock a '91 740 volvo without the key?


We have the '90 940, have you tried this; when the kids are piling out we reach through the back door and push down the lock button on the drivers door, this locks all the doors without the key...also helps if you have an armful of bags..just make sure your keys aren't still inside!!

Volvo slows down going up steep hills when air temp >95 Fahrenheit


THOSE VEHICLES HAVE A SECONDARY FUEL PUMP THAT FEEDS FUEL TO MAIN PUMP UNDER VEHICLE. THE SECONDARY PUMP IS INSIDE THE FUEL TANK. IT IS POSSIBLE THAT THE 2NDARY PUMP IS STARTING TO SEIZE ON YOU. CAUSING POOR FUEL PRESURE AND MAKING VEHICLE TO LOOSE POWER
