More Problems

Okay this whole cooling/heating system is driving me nutz! Anyways I just got a coolant flush, and found out that my water pump is leaking. so i know i have to replace that, but another problem is that all of a sudden, I dont get any heat anymore. I blows really cold air. Being that it is winter, so I would love to have heat. Any help would be great. thanks for the help guys.
I have a 93 Mr2 T.

Your coolant plumbing might have some air in it. Make sure you fill it as per BGB or

No heat after flush = air in heater core.
You need to open the frunk and on the front wall there is some plumbing with a big white plastic screw to bleed out the air with.
You also need to bleed air out of your radiator via the air **** on the top, driversde of the radiator.

thats why i never bring this car anywhere for work. Because no shop knows the correct way to do things. The cooling system is one of the biggest pains on this car and bleeding it is a process. LIke they said, follow the BGB and youll be good to go

Also, it's always a good move to replace the Therostat.

K this is getting crazy. So I aired, or tired to air out the system again. I have come up with to conclusions, either I am doing it wrong, or I have more air in my system than fluid in the car. Anyways I let it run for close to an hour. I never saw a steady stream of fluid. So any idea guys?

Where exactly are you bleeding from? Your post is very vague.

Well, I don't know what to tell you. It's an easy process. With egine running, bleed both those areas, then add coolant/distilled water several times. Bleed, add, bleed, add.

I know it should be, but im not getting any coolant coming out. its just really hot air, an maybe a spit here or there but for the most part it will give a little and than nothing but air.
