It could be a thermostat but it could also be low antifeeze level or a faulty water pump or worn serpentine belt. First check the belt & if worn replace it. Next check your antifreeze level by opening the rad cap with engine cool. Add if low. Start with cap off & see if there is any circulation of fluid in the rad. Wait for engine to warm so thermostat opens. If there is no ciculation, change the water pump. Also replace the thermostat as it is recommended yearly to be on the safe side. Hope this helps you. Good luck!

I need to know about the the cooling fan for the 94 plymouth sundance it is not working any suggestions

Either the fan motor has quit working or the thermostatic switch that turns it on has failed. If you want to check the fan, make up some jumper wires and temporarily run power from the battery to the fan motor. The fan switch usually comes on at 190 degrees f. or there about. It could also be the you thermostat is stuck open and the engine is never getting warm enough to make the fan come on. If your tem gauge reads low, start with a new t-stat.

Temperature gauge goes up then down engine

Sounds like the thermostat is sticking, on warm up on lot of vehicle the gauge goes past normal and when the thermostat opens drops back. If it is going higher than normal, the thermostat is opening late. Needs changing before it stops opening altogether.

2000 acura tl coolant fan after fluid change

New thermostat, installed, saw, new coolant made a little mess filling reservoir, (normal) checked fan fuse for some reason, and condenser fan fuse (xxx ?:), and temp guage, is slightly lower on gauge (than normal?) (disconnected xxxx? quit? a bit? to get to thermosta?.t no dash warning lights have a feeling I popped a relay.


ok, you did a coolant service with STAT,

and it failed.

tell us what works right and wrong, symptoms only.

over heating? parked, (fan never comes on)? as it hits 225F?

under heating? ( fan stuck on , up North can cause huge cold engine)

dash gauge stuck low. (thermostat wrong heat range 180f is best. see FSM for spec. on this temp. spec..

Dash guage varies.? oddly (air in system)?

Dash gauge too high.? (Stat put in upside-down or bleed hole (jiggle) not UP side. higher side of mount , trapping air.)

Does something wrong happen only driving?


does cap on rad hold 12-14psi pressure, hot.?

if car has fan belts, are they tight? (for sure water pump does)

Temperature gauge

check the circuit to the tem p sender unit by removing the wire at the sender and turning on the ignition touch the wire to the head . The gauge should got o hot. This indicates that the wire is ok . Remove and replace the sender unit as it is shorting out inside and is not showing a resistance. The higher resistance __cold water --the lower the gauge reading. The lower resistance the more current allowed through so the gauge goes up

I have a 2001 chevy s-10 showing oil pressure at start up near the max limit (70-75) and drop to about the midway mark of the gauge at idle after warm up. Is this normal or do I have a problem? If so,...


this actually sounds quite normal.
when the oil is cold, it is thicker, and has a higher pressure.
when it warms up, it thins out, and has a lower pressure.

it is also quite normal for the guage to waver a little, going up and down 5-10 psi with the engine speed.

the only time to worry is if you get a sudden drop in pressure when driving.

Noticed temp gauge running a little higher than normal.cooling fans turn on and off very quickly. turned on ac and the fans run. trying to diagnose without getting taken to the cleaners from the...

Check your coolant levels. If the temperature isn't much higher than normal, you may be fine, or you may have a Coolant Temperature Sensor going bad, and reporting the incorrect temperature. Even though the thermostat was replaced 8 months ago, it is possible it is already going bad again. I believe this is more of a Coolant Temp. Sensor fault though. The cooling fans are On when the AC is on. With the AC off, the cooling fans come on when the engine reaches a certain temperature, and cut off once the temperature is back in range. The Coolant Temperature sensor shouldn't cost much, and is easy to replace. I would start with that, top it off with coolant, and then maybe change the thermostat.

0il gauge keep reading low pressure

Either you have low oil pressure , or the gauge or sending unit is not working. Oil pressure on my 94 is quite low at idle , but higher when reving. quickest ,cheapest, easiest, first thing to do would be repalce the oil pressure sender unit.
