Water temp sensor may need to be replaced. If there is no check engine warning, try to borrow an external water temp gauge if you would like to check it yourself.

I have a 1993 mercury' marquis. The floor boads of the front part of the car get hot. And the thermostat keeps falling to c and rising to half way and falling on gage. Can u please help?! Thanks


possible no water in the engine and it is overheating
this is indicated by the temp gauge rising and falling
temp gauge sender units need to be immersed in water full time to get a reading so if it goes up that is in water and when it falls back that is in nothing or steam
hot engine would account for hot floor

My engine overheating problem is in my 2000 land rover. The fan is running and the electric fan comes on at correct engine temperature. After start up the engine runs normal the temp gage rises slowly to...


the usual suspects are:
stuck shut thermostat
clogged raiator
dead water pump
low coolant level
it's sunday, rovers don't work on sunday.
Then again, maybe its wednesday, rovers take half a day then. 25322555-21syibu3fgwpdxocjnkpw0ib-5-0.jpg

95 nissan sentra 1.6L, air fuel mixture adjustment. If adjustment screw is turned completely in how many turns out to proper setting?


1.5 turns for most carbs, but you can use a vacuum gage on the intake to get it right. Make sure engine is warm and on the regular idle screw, then turn the mixture screw in and then turn out until vacuum stops rising. OK?

My car shows it running hot and then cold again whats up


the first thing is to check the coolant level, if coolant is full you may have a bad thermostat or a bad coolant temp sensor,when it runs hot, the best way to determine if it is hot is to check the temp at the sensor with temp checking tool.

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.
