ford tauras engine temp fluxuation

[keith orth]

Hello . New to this site but love the videos. Have a 2000 Ford Tauras 3.0. Have had the heater core flushed 3 times over the last 3 winters(probally need it again). Car was taking forever to warm up. Thought that the thermostat was bad. Changed it last Sat. Now the engine warms up alittle quicker but noticed that while driving and watching the temp guage, that it will drop all the way down to “C” an cool air comes from the vents. It does it a couple times as I am driving. Havnt had time to drive much more than 10-15 minutes at a time. Could I possibly have air left in the system? Have tried to bleed all i could. Now of course we are in the middle of an ice storm(figures) Anyway thanks for any help.

Yep, that could be air. Air bubbles go up, so you have to bleed them out of the highest point in the cooling system. This is sometimes the top of the radiator, which makes it easy, you jut leave the cap off and run the engine for a while, maybe burping the hoses a bit and pouring in more coolant to keep it filled up. You can avoid making a mess by using one of those special tight-fitting funnels that Eric demonstrates.

If the radiator is lower than the top of the engine, then there will be like a brake bleed thingy at the topmost point, usually where the top radiator hose hooks up to the engine.

Can you clarify your problem. When you said the car takes forever to warm up do you mean the engine or the heater or both?
