Have a situation here. My little festy appears to heat up (the temp gauge moves to about halfway up) but all I get out of the vents are cold air. Yes I have it set to the hottest setting. I am thinking maybe the water pump is gone, not circulating the coolant. Or is it possible the tstat is stuck open. Anyone know of a quick way to check before I switch out the water pump. PS. I'm in Canada, its a little cold up here so I need heat.

Im in the same situation with my little beast. My heater goes half way or so up, maybe some more depending on what im doing. I went though the summer with not overheating or anything, so was thinking my cooling system must have been working reasonably well, but when i turn on the heater and put the vents to defrost, i get the weakest heat.
I was thinking maybe about getting a new T-Stat and doing a coolant flush. Any other ideas??? Maybe a plugged Heater core?
Hope we both can get ours fixed. Winter in Canada sucks!

Possible plugged heater core. I'd try the radiator flush stuff first. Make sure you have the heat on while driving around so the flush stuff circulates thru the heater core. Made a huge diff on my 323.90 Festy (Larry)--B6M (Matt D. modified B6 head), header, 5-speed, Capri XR2 front brakes, many other little mods

Check the temp of the upper radiator hose, it should be warm/hot after the gage is at its midpoint.
If so, the heater core is likely the cause.
One thing you might check is if the lever that controls temp, the blue/red background, is actually opening the valve to let hot coolant into the heater core.'93 Blue 5spd 230K(down for clutch and overall maintanence)

The Ford dealers still have the t-stat. I'm on my way to pick it up now.
Ford $22.......Mazda $25
Or, what could I say when I go into napa, like for example, I need an 88 mazda 323 1.6L thermostat? would that work?Last edited by 91blufestiva; 01-18-2010, 04:01 PM.-Josh R

NAPA does not carry the correct thermostat. O'Reilley Auto Parts is a MotorCraft distributor and can get a MotorCraft thermostat for you.
I just bought one. $25. Ford dealer was $41 and Mazda wanted about $33.
Your prices may vary.

I'm thinking about checking mine due the fact that it takes it awhile for the windshield to defrost. All though the car never overheats, unless my battery shifts and hits the wire harness. Which is probably cause the battery is bigger than what the car needs, but its what came with the car.Man should eat when he can for Man does not know when his last meal will be.

well if its that bad use a piece of card board to cover the bottom half of the radiator and some duck tape and do that so it can warm up did it on my truck a couple of times just to have heat when it was cold outsideLast edited by 1988redfordfestiva; 02-24-2010, 02:03 PM.FORD BUILT TOUGH SINCE 1987-1993 FORD FESTIVA LX
