I have a light that stays on looks like a box with cap on top with fluid in it what would that be. Also service engine soon stays on.

Sorry mate, I dont know what this Gas cap is, could be the fuel filler cap, could be the car runs on LPG and it is a cap on the Gas charge line.

You have a real auto repair shop ( not auto parts store) look at stored codes, & any freeze frame data
Do not clear the dash light or you loose data & ability
to diagnose & resolve the issue

• There is a 8mm or 10mm plug on the back of the transmission (underneath the car) When you pull that plug if fluid comes out then it it full. If not you add fluid until it just barely comes out that hole and then the transmission is full.
• Now you add fluid from the top of the transmission. You have to look way down in the engine bay on top of the transmission for a red or black cap. It may say "do not open" or "open by a technician only." Take and pull that cap off and this is the fill spout for the transmission. It's a fill only, not a check. Add from this spout until it comes out that little plug on the back of the transmission.
• You will hear people call this a "sealed" transmission of "non-serviceable." Now you can tell them rubbish lol.
• To check the condition you can look to see if it is getting black or smells burnt. After 50,000 miles the fluid needs flushed and after 100,000 miles you need to change the filter and gasket for the transmission.

Sounds like air in cooling system. Coolant comes through to back of glove box area for your heat supply.
Have you noticed less available heat than normal?

Check the coolant level in radiator, not just the top up bottle. DO THIS WHEN ENGINE IS COLD as hot system is under pressure.

Possibility of head gasket leak suppling gases to coolant system. IF so may be producing some persistant heavy white steamy exhaust, though not necessarily.

Topping up coolant will (should) make noise go away at least temporarily. You should look to see if any obvious leaks or wet spots at hose clamps and heater hose connections.

When engine is cold, open Radiator cap, look down (flash light helps?) to see fluid level, should be full to top.
If not, top up with correct coolant mix, leaving cap off, start motor and allow to idle till warm. If level drops top off some more. Watch the fluid as it flows past cap opening. a few bubbles for a few mins may be normal, but continous stream of bubbles indicate head gasket leak. Turn on the heat in car to full, (not the fan, just heat level) gently rev the engine and top up fluid at same time, (2 people) replace cap. Done. If there are no apparent problems.

If noise returns or does not go away, you'll need a professional inspection.

im guessing that the service engine light is comming on and off instead of staying on all of the time. these service lights come on for a long list of things. this is the time of year when we tend to use all of the power option in our cars. light wipers heater ect it is also this time of year that we find out how good our charging system is working and how good our batteries are. control voltage in most vehichles is between 12.5vdc and 14vdc check engine lights can come on when your control voltage falls below this given level. warning lights could be caused by a sticking thermistat. the difference in temperature from hot water in to cooler fluid out of the radiator should be roughly 6 degrees from top to bottom higher or lower ranges may cause this to light up the check engine light. and there are a host of other minor things that will make the light come on and off. washer fluid levels, brake fluid level being low but not fatal. a missfiring plug at a certain rpm due to carbon build up inside the distributor cap. alot of genaral maintinace type things create this onand off scenario.

I doubt the two problems are connected. I would try a new gas cap and see what happens since it runs fine. The service engine soon light won't reset on it's own right away.

most any sensor going bad can cause the check engine light to come on,try disconnecting the posative battery cable for 15 seconds ,then put it back on,will reset the codes, or take it to auto zone,they will test your computer for codes at no charge to you.i had a venture van my was ox. sensor. thanks robert b.

the service engine soon light means a fault has occurred in the engine or emission system's electronic controls, it has nothing to do with any service you did in most cases, there are over 150 problems that turn the light on, to find out what the problem may be go to any Kragen Auto or Autozone parts store and ask them to run a OBD 2 trouble code test, IT IS FREE. then post the code back here for us to look at, which is also FREE.

The light is on to alert U to the fact that a fault has occurred in the engine management system(s) or a part of the emission control system, there are over a 100 different problems that turn this light on, take the car to any Kragen auto parts,Auto Zone, Shukes etc and they will test the system for free, it could be as simple as a loose or defective gas cap seal, no way to tell until you give me the trouble codes.

the service engine light is prob due to the oxygen sensor being damaged, not replace or you having the catalytic converter taken off---just messing with you. start at auto zone and have then do a free code read then go from there. you should troubleshoot the low fluid level switch for your brake fluid. unplug it and see if the light goes off and if it doesn't jump the two terminals on the harness. oh the car will have to be running.
