Question about 1994 Mitsubishi Montero

Blew a hose

One day about a month ago my Montero started to overheat. My husband checked the coolant and filled up the water. We haven't had a problem with it since until last night while driving on the freeway at about 65mph (we'd been driving only about 10 minutes) we heard a loud POP sound and then it started to overheat and there was a rattling under the hood.
We pulled over and steam started to come from under the hood. Opened the hood to find the large (about 2") hose coming from the radiator had burst. So we obviously need to replace the hose, but what else should we check and or replace and what would have caused this?

The only reason you would blown the pipe is because it sounds like your radiator is blocking up and this time round it has blown your hose i suggest you take the radiator aout of your car and give it a good flush with the hose and if this doesnt work. it means it probably has a small leak and i would put and egg in there i no that sounds stupid but it works trust me. as it will seal the radiator.

It would make sense to have a radiator shop check the flow rate of it before assuming that it is okay; they can tell you pretty quick if the radiator is still doing its job. Check with the BBB for one you can trust, they aren't all in that category.
Another nastier possibility is a blown head gasket; one failure mode is when a combustion chamber is pumping burning gases into the coolant passages. This will rapidly heat the water beyond the capacity of the cooling system to dump the heat. There are other signs too, such spark plugs that appear rusty since when the engine is turned off and cooling down, it may **** water into the combustion chamber.     You do have a problem though, the hose was a victim, not the cause.

Car overheating

You may have a blown engine head gasket. Check your oil to see if it is milky because water is getting into the oil, and check the water to see if oil is getting into the coolant.
If you have either of these, you may need to have a new head gasket for the engine, and hopefully you do not have a cracked engine head.
This will require a fair bit of work to fix correctly. Your local garage or mechanic may be your next call.
There are some products you can use in the coolant for either of these, but it is only a temporary fix.

1994 toyota pickup 4x4 sr5 v6 overheats after changing coolant

Sounds like your water pump may be not working, while vehicle is off try squeezing both upper and lower radiator hose you should be able to feel the fluid in the lines and the hose should feel firm and not squish all the way together. Make sure you used the right coolant orange vs green and mix ratio. after all this has been confirmed start vehicle and squeeze hoses again before they get to hot to make sure the fluid is moving and now hoses should be pretty hard to squeeze at all while the truck is running. if you don't feel movement of fluids or hoses are very squishy it could be a vacuum leak and worst case your water pump, hope this helps-

1994 Lexus ES300 overheats after a few miles and water pours out of the radiator coolant reserve tank. Radiator rebuilt 6 months ago. New radiator hoses and other water hoses within last year. Please...

a cracked block or bad gasket can result in compression bleeding into your cooling jacket causing the symptom you describe. a good shop has a tester to determine if there is compression residue in your coolant. that would be a place to start.

Car has not been driven for about a week, we had below freezing nights for a few nights. light, radio, electrical seem to work ok. motor makes an effort to turn over, shakes a little and makes a squeal...

drain and flush the cooling system and make sure that you use a 50/50 mixture of coolant and water when you fill it back up.

Common issue.... Most people are under the impression that if you use straight coolant in a vehicle, it will never overheat or freeze. WRONG...WRONG...WRONG,

Coolant needs water to activate or it will freeze just like water will.
