Check coolant level and thermostat operation. Sometimes a thermostat will get sticky if not replaced with proper interval.

How do I fix oil being in my radiator but no water in the oil? Oil is not milky or anything on the stick just looks like oil in radiator.


Replace the thermostat. Empty all of the water out, flush with water and a good squirt of dish liquid and run until hot. Drain again and refill with plain water. Empty that and fill with water and anti-freeze.

The air conditioning is completely separate, a standalone system run from a belt on the crankshaft pulley.

Sounds to me that someone has put oil into your water instead of the engine.

My 2001 grand jeep cherokee limited 8cyl seems to get hot. no heat coming out of heater. and coolant comin out of overflow..and trans actin up...help


Hi, It sounds like you may have air in your system, When topping-up all coolant system the system must be purged of air, also another tip is to open the heater valve to hot as if set to cold air will be trapped in the heater and when opened air will go into the engine. open all valves where coolant run's is a must,top-up system run the motor just for a few minutes check water level again top-up if need be and then repeat, If pressure still builds up inside the motor you will need to pressure test the system you may have a blown gasket or liner seal. hope this helps. regards peter

How can i tell when my thermostats bad on my 1999 jeep grand cherokee 4.7l


The best way to test it is to remove the thermostat, and then boil some water in a pot, drop the thermostat into the water and watch how well the thermostat responds. It should open up to the full open position very quickly and if it is slow or lagging to open up, or it does not open fully then replace the thermostat.

I have a 1991 Jeep Cherokee 4.0. It ran fine yesterday then this morning, it would crank but would not fire. I have replaced the spark plugs, plug wires, rotor button, distributor cap, coil, and the air...


spark is triggered by the crank sensor and the cam sensor inside the distributor. but the actual signal to the coil comes from the computer. If I remember correctly the hot side of the coil runs to the back of the alternator. I am sending along a complete wiring diagram for your vehicle but I suggest you get a haynes or chiltons manual for test procedures. Don't follow their wiring diagrams or you will get side tracked to death trying to figure them out (inaccurate is a mild word)

Since I can't do the testing from here, I;m trying to give you the best possible means and chance to figure this out. Any questions just ask!!

While driving the temperature guage flucuates and the heat in the vehicle goes hot to cold intermitantly. I am thinking a sticky thermostat? Do you think this is the problem? Is this easy to replace?


NEED TO CHECK COOLANT IN RADIATOR...NOT JUST OPEN AND LOOK BUT NEED TO BURP SYSTEM SOUNDS LIKE YOU HAVE A AIR BLOCK IN SYSTEM....WITH CAP OFF LET CAR IDLE AND MONITOR THE COOLANT LEVEL...IT MIGHT TAKE AWHILE BUT YOU WILL SEE AIR BURPS...AFTER 20 MINUTES OR SO HAVE SOMEONE REV UP THE ENGINE TO ABOUT 2,000 RPM'S WHILE HOLDING AT 2000 RPM'S YOU TOP OFF THE COOLANT IN RADIATOR. THE FULLY INSTALL CAP..NOW TEST DRIVE

Car stalling with air conditioner on


hello, it sounds like the ECT (engine coolant temperature sensor) is failing, the sensor communicates with your computer and has affect on fuel usage, it is common for bad sensor to allow too much fuel and cause cylinder flooding, this in turn will lower cylinder compression and cause miss, black smoke, check engine lights, easy too overlook without propper diagnostic equipment, easy too change and fairly cheap! good luck, marty

Overheating jeep cherokee 1991


sounds like you have a airlock or air in the system. i had the same problem. there is two hoses that run along the value cover. undo the top one and plug it with a screw driver or something. then the other hose the one that runs to your water pump you need to install a T on it that you can attach a garden hose too. turn the hose on full blast. the water should come shooting on the engine where you disconnecting the hose. let the hose run for about 15mins or so. i jumped on the bumber a bit to shake the jeep. just to make sure all the air comes out. the point of this is that this is the highest point on the engine. so the water should force any air out. jeeps are bad for this any air in the system really messes things up. the transmission thing has nothing to do with this. good luck

DTC P0411/16795: SECONDARY AIR SYSTEM - INCORRECT FLOW DETECTED
Test Requirements
Ensure all fuses are okay, battery voltage is at least 11.5 volts, all electrical accessories are off, A/C is off.
Ensure engine is mechanically sound.
Test Procedure

NOTE
Secondary air system is activated by ECM and blows air into exhaust pipe
upstream of catalytic converter for 100 seconds during a cold start, 41-91°F (5-
33°C). Engine must be cold to perform following test procedure.

1. Ensure fuse and secondary fuse (secondary fuse is 40 amp and is located in fuse holder on top of battery)
are okay. Check hoses and components of Secondary Air Injection System, for damage, loose fit and
improper installation, check vacuum hoses for Secondary Air Injection System. Repair as necessary.
Erase DTC memory. Verify repair. If DTC does not reset, test is complete. Perform ECM relearn
procedure. See TEST DRIVE RELEARN PROCEDURE .
2. Remove engine cover. Disconnect pressure hose from Secondary Air Pump Motor (V101), by pressing
buttons on hose connector. See Fig. 33 . Using scan tool, check Secondary Air Pump Motor (V101) in
scan tool Output Diagnostic Test Mode (Secondary Air Pump Relay activation mode). See OUTPUT
DIAGNOSTIC TEST MODE .
3. Secondary Air Pump Motor (V101) should run in intervals and air should exit pump at hose connection.
If Secondary Air Pump Motor (V101) is okay, go to step 7 . If motor runs and no air exits secondary air
pump motor, replace faulty Secondary Air Pump Motor (V101). Erase DTC memory. Verify repair. Test
is complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE . If
secondary air pump motor does not run, go to next step.
4. Disconnect Secondary Air Pump Motor (V101) harness connector, install LED test light at secondary air
pump harness connector terminals. Turn ignition on. Using scan tool, activate Secondary Air Pump Motor
(V101) in scan tool Output Diagnostic Test Mode (Secondary Air Pump Relay activation mode). See
OUTPUT DIAGNOSTIC TEST MODE . LED test light at Secondary Air Pump Motor (V101) harness
connector should flash. If LED test light at Secondary Air Pump Motor (V101) harness connector does
not flash, go to next step. If LED test light at Secondary Air Pump Motor (V101) harness connector
flashes, replace faulty Secondary Air Pump Motor (V101). Erase DTC memory. Verify repair. Test is
complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .
5. Using DVOM check resistance of Secondary Air Pump Motor (V101) wiring. See appropriate WIRING
DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS. Resistance should
be a maximum of 1.5 ohms for each reading. Check wiring for short circuit to one another in Secondary
Air Pump Motor (N101) harness connector. Repair as necessary. Erase DTC memory. Verify repair. Test
is complete. Perform ECM relearn procedure.
Secondary Air Pump Motor (N101) wiring is okay, go to next step.
6. Check Secondary Air Pump Relay (J299) and Secondary Air Pump Relay (J299) wiring. See DTC
P0418/16802: SECONDARY AIR PUMP RELAY (J299), MALFUNCTION . Repair or replace as
necessary. Erase DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure. See
TEST DRIVE RELEARN PROCEDURE .
7. Disconnect vacuum hose from Secondary Air Injection Valve (N112) and disconnect pressure hose from
secondary air pump motor, press buttons on pressure hose connector to disconnect pressure hose. See Fig.
34 . Blow lightly into disconnected pressure hose, Combi-Valve should be closed. Connect hand vacuum
pump to disconnected vacuum hose and apply vacuum to Combi-Valve, Combi-Valve should open. If
Combi-Valve opens when vacuum is applied, Combi-Valve is okay. Go to next step. If Combi-Valve
does not open when vacuum is applied, replace faulty Combi-Valve. Erase DTC memory. Verify repair.
Test is complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .
8. Check Secondary Air Injection Valve (N112). See DTC P0412/16796: SECONDARY AIR
INJECTION VALVE (N112), ELECTRICAL CIRCUIT MALFUNCTION . Repair as necessary.
Erase DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure.
NOTE: Do not use compressed air to check Combi-Valve.
