Ok i know that i should have completely searched but im tired i stayed up all last night looking for the answer but whatever.

I have 2 problems which means 2 questions so here they are.

1) (heres the more important one) my temp. gauge is always reading somewhat above half but not much over which is normaly not a good thing. now at first i thought it was because the coolant fluid was a little low but i filled it up and its still doing it. nothing smells like its burning and the exhaust doesnt have that burnt smell eather heck it even passed inspection (and in NJ its murder to pass even a brand new car). so what else could it be please help me

2)ok this one i can live with but i would like to see what other people did (i've noticed a few other people with FCs have this problem) my fuel gauge doesnt work. i no its not the gauge because when i fill the tank its reads but for only about 20 miles. so its eather the wiring or the float in the tank...and how do you get the float out if it is that? thanks

sorry if this has been covered if it has just please direct to the thread and close this one or something...again sorry

 

Temp gauge: The easiest thing to do is going to be to drain the system and look at the condition of your coolant. It could be that you have a clogged up radiator or old coolant that has become almost pasty and isnt allowing proper flow through the system. Fill the system with radiator cleaner and water and run it in the car for a day or two. (Attention: If temps are dipping below 32 degrees outside and you dont have access to a garage with climate control, do not do this and leave your car outside. Instead, change the fluid in the morning, drive the car for the day and then drain it before going to bed that night, assuming it's above 32 degrees during the day) The next step I would take is to look at your thermostat and make sure that is not stuck shut. They are generally inexpensive and not too difficult to change.

Fuel gauge: Pull up the rear carpet and you will see an access for the fuel pump. Unscrew the 4 bolts on the cover plate and you will see 2 fuel lines leading to one area. This is where your fuel pump is. First relieve the pressure in the fuel system and then unplug the fuel lines. After doing so you can remove the screws that hold the pump to the top of the gas tank and then remove the pump. Attached to the pump is the float. It should move about 90 degrees i believe. If not, I believe it can be removed easily and replaced.

 

i would buy an aftermarket gauge water temp gauge to get a deffinate on temps

 

thanks...you know now that i think about it the coolant did look a little pasty...hmmm

well about the fuel gauge problem has anyone else experienced this?...how(better yet where) do you bleed the the pressure? thats like they only thing im really not certain how to do.

thanks

 

do you have an s4 or s5 because i think the s4 temp stays around 1/2, and the s5 stays around 1/4. it might not be anything to worry about.

my fuel gauge did the same thing, but it would work when i slammed the brakes, or took a corner hard, and then it would stop working if i did the same thing.

 

If you need some comparisons... On my 88 the temp guage is usually slightly greater than 1/4.

 

It's the other way around S5=half and S4=1/4

[QUOTE]thanks...you know now that i think about it the coolant did look a little pasty...hmmm[QUOTE]
I'm willing to bet that's a large part of your problem. You may want to go ahead and replace your coolant hoses while your at it.

 

My s5 goes right to the middle of the gauge and never budges...

 

alright thanks for correcting me

 

i have the same problem with my fuel gauge but if i pull a hard left hand turn or drift itll read the right lvl..... lol try telln a cop that im sorry sir i just wanted to check my fuel lvl

 

well honestly im not sure wether its an s4 or an s5 its an 87 n/a that has the non circular tail lights im kind of a rotor newb .
ive been trying to figure out what package i have but i get confused because i have some of the stuff from a gxl pacage but none of the markings which makes me think its a standard package...and yes i read the thread that shows what packages came with what but im still confused.

oh yea!! are the gauges supposed to be slow? like when my fuel gauge dies (which is usually about 35k into using a full tank) it goes down supper slow and occasionly looks like its going to ressurect itself but then dies again. my temp gauge sort of does the same thing but it doesnt die.

 

hrm... i think you need to check out the FAQ's... not to be mean or anything... but honestly.

 

i read that and i dont recal anything about slow gauges however no one is perfect and i may have missed that so if i could get a link i would most certanly shut my mouth about that issue
and i also read the thread about the packages but i still cant figure it out which is why i said what i said however if i could get a link to something that better explains it i will stop talking about it (this is not ment to be sarcastic i just dont want to get on anybodys bad side)

 

wait wait wait... an s4 is the 86-88 right? thats only 1/4?! .....holy **** im really over heating

 

No you are not overheating yet, just getting a little warm. Half way on the s4 guage is around 205-210 degrees. Norm is around 180-185. It coordinates with my pda and aftermarket temp guage. I have to watch the vitals ever so closely since I have an e-fan. Another thing to check is the fan clutch.

 

S4's are safe at 1/2. However, "new" S4's were probably around 1/4th. Mine sits between 1/8th and 1/4th.

I would test (or just replace) your thermostat. I had the same problem you're having and it was my thermostat. It decided to somewhat die after 120k miles and 20 years. Who would of guessed?

 

what could happen with the fan clutch? how can you tell?

 

The stock fan is supposed to only operate at under 30 mph (or something there-abouts). I suppose if it didn't disengage and didn't freewheel at highway speeds it could restrict airflow to your radiator.

 

I thought the stock fan clutch was thermally activated and responded to the air temp coming through the rad.

Anyway, the fan is behind the radiator- how could it impede airflow coming in?

 

Impede airflow through the engine bay?

It was just a theory. I do know the stock fan doesn't engage/work over a certain speed though.

That implies that the thermo-clutch is somehow able to detect vehicle speed- which it isn't, all it reacts to is temp.
If all is going well, above a certain speed (45MPH?) the airflow through the rad is sufficient to cool down the clutch's bimetallic strip and it disengages, but all bets are off if airflow is impeded or the clutch malfunctions.

 

can i ask you guys one thing that has been bothering me?
well...um ill just ask it anyway...
my car has this turning over problem after the car has been turned off(the temp is up to correct temp so its not flooding) and then let cool for a while. when i go to turn the car back on it will have trouble staying on. the thing is... this isnt a constant thing. sometimes it happens sometimes it doesnt.

(uhh its difficult to explain) it will crank, turn over then struggle to stay at idle then just die (i would repeatedly try to start the engine after)... one time it even was unsure if it wanted to die and the engine was just idleing at like 400. it couldnt be the starter because its turning the engine over right?
any suggestions would be greatly appreciated (even if it was just a link to a thread were someone had the same problem)

thanks

 

than fan shuts off after 25mph if i remember correctly. Even if it stayed on, it pulls air... so it would be unable to restrict air flow i think. and if it was stuck in the always on postion, id imagine its be stupid loud at anything above 50mph.


as for you fuel gauge problem. i have the same thing in my s5, and on my 2nd S4 a year back. your fuel level sender is corroded. if you pull your fuel pump out you can see it.

It has a float, and as the float raises up the resistance measured increses or decreses, cannot remember for sure, perhaps one of the gurus will chime in. I tried cleaning mine to see if that would help, it did not. i beleive you just have to replace it. its not hard, i can tell you that much.

 

thanks for all the help, ill probably do the radiator flush and the fuel sensor float over the weekend (unless my stupid job interferes). if i could just figure out whats wrong with what i said about the start up thing...i would never bug anyone ever again about any repairs...ever. (mainly because thats my last major one and i know how to fix the rest)
thanks again

 

check your plugs to see if they are crapped up?? maybe engine is heavily flooded.

asking questions is how you learn, i just prefer to read and research first... usually the topic has been covered over and over again since these cars have been around for a bit... nothing really new to talk about anymore... sorta...
