I have a Toyota and they are not good at fog. go to parts store and rained makes a product fog x easy to apply you apply on the inside its about5 bucks or less it works

bad heater core!!!

We have no diagrams or repair manuals for this make and model year.

It will be the heater core. If you can smell it inside the car and it's steaming up the windows the core will need to be replaced. Remove the heater core housing and check to make sure its leaking from the core itself. You might get lucky and have a leak from the hoses running to core instead. Hope that helped.

check your heater core could have a leak and it will steam up windows

First you need to gently pry the plastic facia around the heater control out. Then remove the heater controller. Pry open the heater control tabs to enter it and there is the 3 bulbs. These bulbs are not run of the mill and your best bet is an actual car parts place to obtain them. I would change all three while you are in there.

Check the actuator

lets start with the heating up problem!
replacing the thermostat and relay has nothing to do with it. common causes of heating up are improper valve setting timing, mismatch air-fuel ratio, worn-out piston rings, poor oil flow, poor radiator coolant flow.
i suppose you have changed your car motor oil. recheck if its on the right amount.


loss of power:
Common Causes
loose piston rings (causing insufficient compression: indications fog like smoke), air-fuel ratio incorrect, blockage in air intake.

check also for air on the fuel hoses if you experience often jurking problems regularly clean fuel strainers or filters.

toyota ed is on the money mate you got a leaking heater core and it is a ***** to change recommend you go to a mechanic to do it properly, sooner the better as you can damage your engine if it keep getting low on water
