1980 toyota pickup 20R engine

[Buelligan]

Can anyone email me a few pictures from the manual regarding the heating system?
I just purchased a 1980 toyota PU 2WD long bed, and the heater isn't working. I'm assuming either the cable going to the valve that allows water to go to the heater core is bad, or perhaps the heater core itself.
I'd like to see just how hard it's going to be to take the dash apart to get to the heater system, and where the location of that valve is.

Also, the tach isn't working, or the oil pressure gauge, I assume the tach connects somewhere around the coil, where is the sending unit for the oil gauge?


Thanks !

Try your local library for a manual.

The valve is on the fire wall, won't be hard to find, just follow the 2 heater hoses. Then move the heater control slider from cold to hot and see if the valve changes.

If it doesn't move it's the cable (common problem). If it does move leave it in hot with the blower on (the blower fan does work, right?) and let the vehicle warm up real good. If you have no heat feel both heater hoses. Both should be hot, if the return isn't the core may be clogged.

Oh yeah, the tach connects to the coil/ignitor and the oil sender is near the oil filter.
