360 coolant leak

Hi I notes a leak coming from the water pump, I removed the panel and found the coolant is coming from the back of the water pump assembly, I see green coolant on the top of the engine and drips in the front of the pump. could it be happening from the thermostat or a gasket? Any suggestion?
thanks.

Your heat exchanger is back there, the thermostat is in the front, just right to your arrow.

 

How hard is it to remove it? Should i check where the leak is coming from with a scope camera or for sure thats the problem? Is a comune problem this?

 

First thing is to check your coolant reservoir to see if you see any oil residue in your coolant. If so, stop driving immediately. Then you can further your investigation into the leak.

 

Judging by the pic of the engine on a pallet I suspect he stopped driving the car already.

 

I’d suggest re-reading the initial post.

 

Definitely use whatever method to look under the intake plenum .. there is a few clamps , a water temp sensor etc that can be causing the leak .. just try to wipe everything off and then see where it is coming from

Look at a parts diagram to see all the different clamps , parts that are under there to see what to look for ..if that helps

Also as mentioned above , a freq problem is the heat exchange goes and the gearbox oil mixes with the antifreeze .. that will be shown in more so in the gearbox oil but also can see that in the coolant reservoir. When the exchange goes ..it goes internally so no leak outside of it ..so even if you have one it doesn't mean you have the other

Start by look where it is coming from ..use your endoscope and little mirrors etc

Historically one of the first visible symptoms of a failing heat exchanger is coolant on the floor. Happened to several on this forum and is usually their first sign that something is wrong.

 

That is usually causes by overflow from the gearbox or overflow from coolant reservoir due to coolant mixture causing pressure overflow iirc

But OP should check as you said but also not jump to that conclusion until he does a good visual, checks gear oil etc as mentioned above

But the telltale sign is the oil in the gearbox if an exchange fails ..the pressure of the coolant pushes it's way into the gearbox oil

Coolant is really green. No sign of oil mix .
The car had mejor service done 2019 including a plug under the water pump.
ill try to post more pic tomorrow.

 

I forgot to mention to find the leak where it was coming from i had to put 15 pound of pressure in to the system and after few minutes i saw coolant coming down feom the pump assembly.

 

Lol. I did not have any pic i used one from the web.

 

This is what i can see. Take a look. Can u tell where is coming from?

Look like it is coming from the rubber sleeve on the end of the heat exchanger ..it could be as simple as the clamp around that rubber sleeve is not tight

Like all leaks sometimes what you see may not be it since it travels but it does sure look like that from you pics

I attached a pic to show what I referring to Image Unavailable, Please Login

Yes thats where is coming from. The boot on the HE. I dont want to remove the pump and assembly, do uou tink by just tighten the clamp will it do the job?

 

I would try it .. you will know immediately if you see the clamp is loose

I would say 30 mins is enough but remember heat plays a factor here so if you don't see anything for 30 mins I would then drive it up to temp and also look ..

I would say after one "hot" drive and no leaks you should be fine

Glad you found the issue

Yes. I will do tomorrow start it up and bring up to temperature and will check again.

 

Any updates

Trying to do it between work and free time. I m continuing to look at the slow leak. I tide up the boot in the back of the heat exchanger and put 5 pounds od pressure over night. I still see a drop of coolant coming from the boot at the and of the heat exchanger. My son has a small arm Will try to tide it whit a 10m and see if the leak disappear.

Today my son tide up the clamps on the heat exchanger and the leack got much worse. We couldn’t stop it. I m not sure what happened
Did he over tide it? Now we are in the process to remove it. Any advice ?

 

Not sure what happened there ..could be the rubber has a split in it. At this point need remove and check both the rubber and the mating surfaces ( heat exchange lip)
