After much worry about my own blown and leaking heater core (85 Toronado) I at first by passed it, but with winter coming I HAD to fix it, but was unable to get anyone to do the job; and pulling out the entire dashboard and dropping the steering colume for a $20.00 heater core seemed to me to much....so here it is, first I do not consider myself a HACKER when working on cars and did make a very exceptical repiar by carfuly cutting a hole in the fire wall and pulling it out, you will be surprised how easy it is to cut this hole with a small chisel or screwdriver and a hammer CUT LIKE BUTTER!. I marked out an area around the heater hose's about 10"X10" inches and just (tapped on the chisel) all the way around. this worked better than I expected, so I pulled out old and in with the new, I was even able to put the peace of firewall back in place with some bondo and flat black spray paint the completed job hardly left a scare! saved me a ton of work. PS I drove the car another year before the motor died at almost 300000 miles, best car I ever had.....hope this helps....Todd
Yes in the '79 to '85 toronado's. You will need an olds 350 engine such as the ones put in the '79 toronado's.
When replaceing the toronado engine, The intake and carb must come from a toronado or Riviera because it is lower. The 78 came with a 403. A 307 or 455 Olds engine will work also as long as you put the low profile intake on

An olds 350 engine such as one that they put in the 1979 toronados. Don't think you could put a Chevy 350 in without major mods.
This depends 100% on what engine it is.
pull the fuse
To replace a starter in a 1985 Olds car, raise the front end of the car with a jack, Next, remove the two support bracket bolts at the transmission and pry the support bracket away slightly to obtain access to the starter bolts.
The SuperChip i installed in my 1990 oldsmobile toronado trofeo gave it 25hp more according to the dyno.
the starter may be worn on your car if it starts up easily when its cold but slowly turns over when it is at the operating temperature. Replace the starter to your engine.
P235/75R15 or P235/70R15
Depending on the year of your Oldsmobile Toronado, the dashboard is held in place by 12 to 15 retaining clips. Remove the retaining clips by prying outward. The dashboard will come off.
It's above the glove box liner behind the dash on pasenger side..
Personally you can not rebuild a steering colum you have to find a professional.
No, it is obd 1.No, it is obd 1.
It is located in the lower dash, below the glovebox. You have to remove some interior trim pieces to get to it.
The Rocket 350 oldsmobile engines will bolt in as well as the Rocket 455 olds.
There seems to be two parts to the water pump and the fan is what usually goes first. Olds. was smart enough to just male that part to replace only. I was replacing the alternator on my 91 and decided to replace the water pump part I was speaking of. It's cheap and easy to get to. Hope this helps in some way.
Possible ignition module problem.
Through the dipstick tube coming up behind the engine, right behind the distributor.
