While driving down the road in my 2003 pontiac montana. The change oil light comes on and high temp warning light comes on. When the high temp light comes on the van losses all power.

Check the coolant first. Add as needed. Once full. heat it up in the driveway and check for leaks. 3.4 montana, I would guess the water pump. Change the T stat also.

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.

You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

The top radiator hose was replaced now the temp goes to the red zone ,when the heat is on high the temp slowly rises and when the heat is on it slows the heating down

The system may have an air pocket in it. I remember the Toyota 3000 V6 were great for doing that. Look for a heater hose or something high on the motor that you can pull off to fill with more coolant.
If its not an air pocket then the thermostat could be stuck or the electic fan not coming on.

Hi, i have a mitsubishi montero 01, the air condition stops working due to leakage and my mechanic decides to remove the leaking pipe that goes to a unit(i dont know the name now) above the right rear tyre...

Make sure you have water in your radiator! The leaking is probably coming from there or a hose linking the radiator to the engine block. If there's no water, fill it up again (make sure your engine hasn't been running for awhile before opening it up). If there is water though, check for any hoses running the radiator to the engine if you can see them and make sure they are tight, look for wet spots on the hoses to see what might be leaking.

If this solves it, take it to another mechanic!

Over heating on gauge, both fans on rad.

I would say check your coolant level, and change your thermostat. And see if it is high fans or low fans when they come on. There is a fan control relay down on the drivers side frame right under the air box that goes bad too if your fans arent working quite right to check if all else.

Temp gauge goes high. Radiator leak just the

It could well be a faulty thermostat- test or replace same.
Could also be a blocked radiator core, - check coolant or airflow is not restricted,
Ensure any radiator leaks are repaired,
Ensure coolant level is correct, without airlocks - bleed as necessary on re-fill,
Check operation of cooling fan - ensure fan runs at appropriate engine temperature - if not check sensor switch and associated relay operation.
Thermostat is located at the end of top radiator hose where it connects to engine housing.
