Coolant leak?

You will need to visually inspect the components under the hood. Inspect the coolant reservoir tank, radiator, radiator hoses, thermostat and waterpump. These are the most common components to fail and cause coolant leakage. Let me know how the visual inspections come up and I will follow up after looking at this guide

Please run down this guide and report back.

What makes it tough is, without seeing the leak source, it is hard to know. It may be a simple as a clamp loose. You need to use mirrors and good lighting to try to get to the source while the system is under pressure. Sometimes you need to start pulling of things to make the area accesible.

Lower radiator hose
its goes to the water pump

The leak may be internal or external.

Are you seeing it on the ground or smelling coolant at all?

How fast are you losing it and having to add more in terms of mileage traveled?

Must be a large leak somewhere. Will need to inspect all coolant components, especially near where the coolant was found. Check radiator hoses, radiator, thermostat housing etc.

Hi there,

Although I can't find any pics to back up my diagnosis, if there is coolant leaking from the bell housing and you can't see and leaks, I feel that there must be a core plug behind the drive plate, most cars have then there, may be a call to the dealer will confirm this for you.

Replace the hose. Refill coolant. Check for leaks. Hoses get worn over time. Hopefully this hasn't done any lasting damage as long as you stopped straight away. Once you have repaired vehicle. Have the coolant sytem pressure tested to be sure?

Hi there e you will have to replace that faulty hose, this is not hard, when replaced re fill coolant and bleed system of air, make sure that you have the heater on, it may be a good idea to replace the top hose as well while you are doing this job.

Do not let it over heat have it towed
let it cool and check where is the leak from
possible water pump

WARNING: NEVER REMOVE THE PRESSURE RELIEF CAP UNDER ANY CONDITIONS WHILE THE ENGINE IS OPERATING. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE COOLING SYSTEM OR ENGINE AND/OR PERSONAL INJURY. TO AVOID HAVING SCALDING HOT COOLANT OR STEAM BLOW OUT OF THE COOLING SYSTEM OR DEGAS BOTTLE, USE EXTREME CARE WHEN REMOVING THE PRESSURE RELIEF CAP FROM A HOT COOLING SYSTEM OR DEGAS BOTTLE. WAIT UNTIL THE ENGINE HAS COOLED, THEN WRAP A THICK CLOTH AROUND THE PRESSURE RELIEF CAP AND TURN IT SLOWLY UNTIL PRESSURE BEGINS TO RELEASE. STEP BACK WHILE THE PRESSURE IS RELEASED FROM THE COOLING SYSTEM. WHEN CERTAIN ALL PRESSURE HAS BEEN RELEASED, PRESS DOWN ON THE PRESSURE CAP (STILL WITH A CLOTH), TURN AND REMOVE PRESSURE RELIEF CAP.

If it is under the water pump, then it is likely that the water pump is leaking itself. When the car is running, there is a little less pressure being exerted on the any one spot in the cooling system than there is when you turn it off after it's warmed up. It is a basic rule of physics and fluid dynamics. So it leaks more while sitting and not running. Also, while you are driving, wind/air is being blown at it and dispersing any fluid that does come out, so it does not appear to leak. It probably is leaking while running though.

Option A: My suggestion to you is to borrow a pressure tester for the cooling system from the local car parts store (AutoZone, Advance Auto, Oreillys, etc.). With the vehicle off and cold, take the radiator cap off, hook up the pressure tester, and pump it up to 16 PSI. Do not put more than 16 PSI on it, as that could damage things. Then follow the hissing sound to your leak.

Option B: is to fill the cooling system as much as possible. With the cap still off of it, start it with the heat on full blast and let it idle a few minutes while you keep pouring water in it. When it appears to not be taking any more water, turn the engine off, put the radiator cap back on, and then start it again. Watch closely for the leak. Follow it with a flashlight if possible. But be careful because the electric cooling fan can and will come on without warning.

Option A, is the more professional way to do it. Option B, is the more backyard way. Go with Option A if at all possible.

Let us know and we'll go from there.

You need to recheck the coolant level for it to over heat like this you must of lost your coolant
I would check for leaking hose the heater hoses rust and leak all the time also check bypass hose
check water pump and radiator
if no leaks
check and or replace thermostat

good luck
