My car engine never heats up so it dies ever time it idles in drive. will start right back up, though. Someone told me the engine fan is directly wired so it runs continually. I do I fix this or what can I expect it to cost to get it fixed

Hi, if the fan runs contiusouly then the stat in the radiator / engine is CLOSED CIRCUIT. this is a 2 wire unit usually in the radiator. or this unit has been shorted out because the radiator thermostat is busted. the cutting out is more then likly the thottle stop needs to be adjusted. gerry

It will depend on why someone wired it this way. The system is designed to use input from the temperature sending unit and throws a relay when the indication is above a certain temperature. If the system components (sender, relay and wiring) are still in place and functional, it would be a simple matter to hook them back up. But if they did this because it wasn't functional, you may have to purchase new components to get the system working again. You might also want to verify that they didn't remove the engine thermostat, as that would also prevent your engine from heating up as quickly as it should. If you have more questions, please feel free to reply.

1991 Cadillac DeVille (has 110,000 miles on it) suddenly dies while driving. Starts and idles fine, but shuts off after driving only 1-2 blocks. What's wrong and how do we fix it?


There are many things that can contribute to this problem. It sounds like it may be ignition related. Possibly an ignition control module or ignition coil. The check engine light coming on while driving is the key to finding the problem. The light comes on when the computer finds a problem and will then store it in its memory. Have the codes checked for what the computer has found to be at fault and with a little diagnostics, should lead you to the problem

Will stall while idling in drive and not restart right away. Jeep will seem to turn over, and RPMs rev up, then the engine dies.


no its more than likely not related to the trans,if you are having shift problems though,i would have the tps(throttle position sensor) checked out.another thing to check is the vacume lines to and from the egr valve and the valve its self for proper operation.

My 2000 VW Beetle idles really rough and loses


I had that problem for the longest time. I had to clean the Mass Air Flow Sensor. Very easy to get to. Go to any auto parts store and ask them for the MAFS Spray. If cleaning it doesn't work, you may need to replace the MAFS. Once again easy to replace. Make sure you put it back nice and tight.....

Lexus sc300 engine problems


Does the car only die at idle with the A/C on, or does it kill the engine when switched on at road speeds? Are there any belt slippage noises (Squealing sounds underhood) when switched on prior to dying? A locked compressor will kill an engine at idle, but should squeal like a stuck pig (belt slippage) if switched on at speed (with a noticeable decrease in power) and will stall the engine when the throtle is let up.

A short in the compressor clutch could kill/depress electrical power to the engine sufficiently to kill the engine, but this should also blow a fuse unless it has been bypassed to "correct" a previous fuse blowing problem.

When the A/C is switched on, there is a throttle idle position compensation to accomodate the added load of the A/C system, and if this is not functioning it could cause the engine to die at idle with the A/C on, but it should cool normally at road speed if this were the problem.

There is also a secondary radiator/condensor electric cooling fan underhood that is turned on when the A/C is on to insure enough air is moved across the condensor coils to transfer (remove) heat from the Freon coolant, and a short in this motor or circuitry could also possibly cause a similar problem, as could also the interior fan system, though this is pretty unlikely.

With the engine off, locate the compressor/clutch underhood, and determine if the center hub on the clutch rotates freely or if it feels locked. If it feels locked, have someone start the engine and engage the A/C while you observe what takes place underhood. If the compressor clutch engages (with a noticeable "clack" sound but the center hub doesn't turn, you have a seized compressor which will need to be replaced. If it does turn but the engine does die, I'd suspect one of the other faults described above.

Hope this shed some light on the problem, and good luck!
