What makes a 04 envoy run hot and lose oil?


A hot running engine is usually caused by a cooling system problem. Make sure the coolant level is full and the thermostat.. rad fan.. radiator cap and water pump are all functioning correctly. Make sure there are no restrictions in front of the radiator to obstruct air flow and coolant circulates properly throughout the radiator. As for losing oil, check for the obvious..... Leaks. If no major leaks and you have a high mileage engine, suspect the oil to be burning within the engine. A constantly hot running engine can also cause the oil to break down quicker resulting in consumption, especially if oil changes are neglected

Tranmission overheat light


check for oil level in the transmission9over full or not enough will cause this fault
check condition of the oil and if not as new then change it and clean the filter
while the pan is off then have the bandss and clutch pack adjusted to remove the possibility of slippage
check for engine operating temperature as the transmission oil cooler is in the tank of the radiator and if the engine is running too hot then the transmission oil will also be too hot.

I have a 1998 dodge stratus. 2.4 L 4 cyl engine. smoke began coming from the back aarea of engine just in front of dashboard; radiator full. not running hot. oil level ok. no leak. no light indicato


Could be oil dripping from the valve cover onto the exhaust pipe.
One drip can cause alot of smoke when it hits the pipe.
Could be power steering fluid too.

Will a leak cause the radiator fan relay curcuit to malfunction on a 2003 jeep liberty 3.7


a leak in coolant system will cause air pocket in the coolant system around the engine coolant temperature sensor.coolant sensor is a thermistor in which when hot cool cause it resistance decrease which affect the voltage from sensor to pcm which will cause engine coolant to turn on.if coolant level okay,check coolant fan fuse and relay, if all is good,engine coolant temperature sensor could be bad or have vechicle code scan for pcm problems it control the coolant fan.fill coolant system to correct level make sure engine coolat reservoir is at full cold mark and not empty.fill coolant system check for leaks,refill coolant overflow jug back to full cold mark dont over fill, if coolant overflow stay empty you have leak either its leaking or you have radiator hoses or radiator leaking coolant.when coolant overflow jug run dry it cause air get in coolant system causing overheating problems.

Oil press motor light after an oil change..now car is running hot informing me to check coolant, when coolant levels are find. I already replaced fan clutch, radiator -coolant flush, and replaced...


This may be a simple thing, don't get to nervous just yet. A similar problem came up the other day on fixya.com in reference to another car. Because of the way cars are designed now a days it just may be possible that you have an air bubble or pocket. Usually this happens in engines that sit a little lower than the heater unit. The way you describe your problem with an oil change first, then car running hot, may be purely coincidental. Try these checks first.
1- check for leaks around the engine, any hoses you may have removed when replacing the parts you replaced, thermostat goose neck, and if after filling your radiator has the level mysteriously gone down.
2- is it possible to see and check your water pump, if you can grab the pulley and yank on it hard. Does it have play, if so it could be bad and leaking through the weap hole.
3-you may have a bad head gasket (BLOWN). This could be putting oil into your antifreeze or antifreeze into your engine. If it's in your oil you would have seen this when you did the oil change CHOCALOT MILKSHAKE and more than five quarts. If it's going into your engine then it's coming out your exhaust. When you start the engine, if the exhaust smells SWEET your head gasket is bad.
4- you say coolant temperature light on and coolant level OK. If as I said in the beginning AIR BUBBLE . Remove your radiator cap , run engine to operating temperature, put on your heater, fill your radiator till it maintains proper level. I hope it's this simple for you. GOOD LUCK.

My Audi 80 seems to emit blue smoke from the exhaust when it is hot, the oil pressure is high and car runs fine. The temp guage is not working. Might this be a connected to problem?


1. check if the water/coolant level in your radiator/reservoir is decreasing. if yes, replace your head gasket.

2. check if oil level is ok. you can check it by looking at your dipstick, if the oil is not on the recommended level. have a mechanic check if there is oil in your combustion chamber. oil in combustion chamber can be caused by a lot of thing. ex, leaking valves, cracks/leaks in the cylinder head, blown head gasket, etc.

I have a 1995 Jeep Cherokee Sport 4.0. I use it on the mail route. It seems when it get hot it builds pressure and leaks fluid somewhere. You can not see where it is leaking but it looks like it is on...


Yes, mine did the same thing.
The auto trans is building up to much pressure, it will need a full service to stop this happening, also get the cooling oil lines checked to make sure they don't have any kinks and squashed areas in them.

The plastic box that you put anti-freeze in; having to replace it with a full thing of anti freeze- weekly. No leak is visible. What is it?


No sign of leak means that your vehicle is likely burning it. An internal coolant leak will cause this. Bad gas mileage, white, sweet smelling exhaust will confirm.

This will likely destroy your motor and exhaust soon.

Engine smells like rubber burning and temperature gauge at normal temperature. Water/coolant leaking out of reservoir and needs to be filled ever 2 days. Oil level is normal, but when it's hot outside the...


Generally that smell is caused by an oil leak that is getting on either the exhaust pipe or manifold (doesn't take much to smell). As far as bottle getting low, I've got a 93 that never stays full but only needs coolant in the radiator about once every two months. Been like that for two or three years and has never overheated. I'm sure there is a small leak somewhere, but I'm not driving myself crazy looking for it. Check all hose connections, and look on the ground after being parked overnight...If it's leaking, something will show up. But if the radiator is staying full, just check it when checking oil level.

Lost oil pressure, got hot and started leaking oil. Couldn't tell where the oil was coming from.


sounds like the engine may have failed, but if u want to see where the oil is comming from buy some engine clearner spray down the top and bottom of engine and hose off, then run it and look for the leak, make sure the crankcase is full before u do this and that it has oil pressure, no use making things worse, u could also use a pressure washer, they are cheap to rent. Check around the oil filter 1st
