Re: 99 Ford Taurus help for dummies
That is the manual system. The coolant you just check it's color. If it's lime green the it's clean. If it's a greenish brown or muddy brown it's overdue for a flush. With the engine warmed up you can check the temperature of the heater hoses going in and out of the heater core. They should be pretty close in temperature. If the outlet is cold and the inlet is hot you have a blockage in the heater core. You will see where the heater hoses go from the engine to the firewall. The heater hoses are towards the left side low down. The A/C lines are to the right. there have been a few members that have found corroded water pump impellers, but they usually have an overheating problem with it. See what you find and we'll go from there. Caution!!! The heater hoses can get hot, wear some gloves when checking the hose temps. They don't have to be too thick.
