I'd venture to say that it's that wonderful GM factory coolant. If left in over xamount of miles, it will eat your seals and **** up your engine. I had to replace the intake gaskets for this reason. Drain it quickly, flush it till it's clean and don't put that GM anti-freeze back in!

Will not go into reverse.


Hi, have you checked the fluid level on this ? If the fluid smells burnt and is brownish in color most likely the first and reverse clutch has burned out, or the rear reverse band may need adjusted.

If your fluid is a mid to dark brownish color it may need rebuilt and if it smells burnt also.

The reverse and first gear shift work off the same clutch pack inside the transmission and off the reverse band as well. Also if by chance the reverse band spring is broken or the piston push rod has broken will cause loss of reverse too. The forward gears will still work but may get sluggish and take time to engage over time.

Check the color of your automatic transmission fluid - it should be a bright pink or light red. if it looks dark red or a brownish color, you need to have your system flushed and replace with new fluid. Have your mechanic check your modulator valve.

I have oil in my radiator. Is this caused by blown head gaskets/cracked block and can this be repaired?


If your car is an automatic, it's most likely transmission fluid. There is a cooler inside your rad for trans cooling and it will rot out over time. If the oil in your rad is a brownish color as opposed to black, it's ****** fluid.

Head gaskets are replacable for sure. You shouldn't have to worry about a cracked block unless the engine has suffered from extreme heat or freezing. Hope this helps.

If it was a red colored fluid it was transmission fluid. You need to check that on level ground with the motor running to be sure you get the level correct. Normally you have to pull all of the Pan bolts to drain this but every so often Toyota puts a drain plug on the transmission. Make sure you haven't over filled that.
The engine drain is at the rear of the motor on the bottom. On a side ways mounted engine that is the side toward the firewall and will be a black or brownish color.

Radiator flushing , brownish coolant in reservoir


That brownish color is caused by oxidation(rust) of the waterways in the engine block. Dont worry, your engine wont rust through. This is normal on any car. Just flush it out until the water runs clear. Refill with water and use a good antifreeze as well as it contains rust inhibitors.

Cant get top gear when engine warmed up 280se 126 1984


ok.. so find the transmission dipstick and pull it out with the engine running, if the fluid is red...very red like blood red then you probably need a transmission flush make sure the flush includes the transmission fliter changed. if its dark or brownish color...sadly you will probably need a transmission..if it's low on fluid ,add trans fluid ... a junk yard unit should be no more than 500 dollars

Coolant has oil in it. The fluid in the radiator is a brown color . What to do????


get it flushed out and replaced with new coolant but it looks like early signs of a head gasket starting to go .after flushing keep an eye on color if its the same brown color two weeks later you have a bad head gasket.

Fluid leak, gears won't shift/engage and car begins stalling


Some of these have a small dipstick on the top of the transmission it to check and fill. Do not over fill this it shouldn't take to much to fill. You can try that and see what happens. Transmission fluid should be pink or redish in color if its dark or has a burnt smell then you have a problem. See if this information was help full.

I need to know what the part is called and how to fix it. The part is leaking hot coolant fluid, it is a ''y'' shape tubing that feels like hard plastic, black in color. It runs on the left side to the...


sounds like hoses going to heater core but they are rubber usually. But it could be the hoses for the degs bottle mounted on the passenger side inner fender.

Coolant Recovery System NOTE: When the water thermostat (8575) is closed, coolant flows through the degas tube and hose assembly from the lower intake manifold to the radiator coolant recovery reservoir (8A080) .

Trapped air in the cooling system must be removed. A pressurized radiant coolant recovery reservoir system is used which continuously separates the air from the cooling system.
  • When the water thermostat is open, coolant flows through both the small hose from the top of the radiator outlet tank and the degas tube and hose assembly from the engine to the radiator coolant recovery reservoir.
  • The radiator coolant recovery reservoir separates any trapped air from the coolant and replenishes the system through its radiator coolant recovery hose.
  • The radiator coolant recovery reservoir serves as the location for:
    • service fill.
    • coolant expansion during warm-up.
    • system pressurization from the pressure relief cap.
    • air separation during operation.
  • The radiator coolant recovery reservoir is designed to have approximately 0.5-1 liter (0.53-1.06 quarts) of air when cold to allow for coolant expansion
