First thing I'd do is check actual temperature (you can have a shop do this with a heat sensing gun, or just tape a thermometer to the upper hose and read it.) Make sure the coolant level is full and that the electric fan is coming on. If the system is working properly, then you will need to check temp sensor and gauges.
This isn't a "fix" only because you need to find out whats happening in order to know what to fix.

Wont start after driving..


first see if its got a check engine light if it does that could be the answer to the problem. next if you mean you put the car in gear and rev the engine and it goes nowhere than the trans is either bad or the shift sensor is. i doubt its the coolant temp sensor a good test would be to just let the car idle for a half hour and see if the radiator fans come on. but like i said check the engine light first.

Won't turn over. The instrument cluster won't work


ok iif the instrument cluster does not work.. before i give a solution can you tell me if it have atach and temp gage not a temp gage witha idiot light but a actual temp gage.. because if temp gage and fule gage hands are not in their proper place like if yo uhave a 1/4 tank of gas and it reads way past full and the temp gage is gone out of site way past say 240 degrees then it is your speedo head .. have this trouble the other day on a chevy 2002 cavalier.. replaced the head and wahla the car started. it seems the speedo head is tied in with the computer system on these cars.. and if the tach is not working you need not worry if you cannot find a head with a built in tach.. a normal speedo head with out the tach part will also work.. just when you change the head count the pins on the old one and compare it to the new one if they match then just plug it in and car should start..

No Heat in 99 Taurus


Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.
