coolant leak

[joe11111]

hey all,

ive got a 2017 mustang gt base model, with 57k miles. its had a coolant leak for a few months now, not too bad but enough to notice almost on a daily basis. ive taken it to a couple ford dealerships with no fix so far. one place replaced the radiator, said it had a crack where one of the hoses connects to it and the other place did a pressure test but found no leak. the 2nd place did find an a/c line leak so they replaced it and the compressor. coolant leak issue remains. they are starting to think im crazy and making it up. not sure what to do at this point, any advice will help. ive added a pic of the issue which is from a few days ago. sometimes its a small leak sometimes larger leak.

that large a drip should be traceable and a pressure test should reveal something.

I had an almost identical situation to what you described on my 2016 convertible. I had a leak, then had the pressure test done and the shop said there was nothing wrong. Few weeks went by and there was another leak... same thing. I was pissed that it kept happening and that nobody seemed to know where it was coming from. Finally it happened a third time with a large puddle of coolant under the car and Ford figured it out and had the coolant leak fixed under warranty because the water pump went. I was at 59700 miles and was so lucky that Ford did it under warranty with that mileage. Your leak seems VERY similar... Maybe have them check the your water pump to see if it is the culprit.

Yea, it has to be either the water pump, or at the bottom of the overflow bottle either the hose is cracked, loose or the nipple it slides over is damaged…. Especially if you already had the radiator replaced.

Check all clamps on all rad hoses and are sure the clamps are tight.

thanks for the info guys. im taking it back to the dealer tomorrow and asking them to check the hoses and especially the water pump.

The usual culprits I see are water pumps and the quick connect fitting between the upper radiator hose and the t-shaped hose that it connects to (replace both hoses). With a puddle like that...someone isn't doing their diag right. It's basic CSI - lift the vehicle and follow the fluid path lol.

Get the car up to temp and while it idles get a flashlight and watch, sooner or later it will drip

My 2016 v6 had a similar issue, was a water pump, very hard to spot the leakage, because of where it’s at, and driving the car flung the coolant everywhere, looking like it wa other hoses etc… also had a small leak in the ac lines. Hopefully they get you fixed

update on the coolant leak issue. good news is the issue has been fixed with a new radiator. bad news is the dealership 'supposedly' replaced it back in June but seems it was never replaced on the first visit because looking at the new one now, its easy to tell that its a new one (its all clean and shiny) when back in June , the radiator looked like the original one and the leak was still there.

Glad to hear it OP. Some of those dealers are absolute scumbags. Always inspect the areas the dealer/repair shop checks out upon a visit. These fools have a tendency to charge for a service when nothing was actually done. Look at all the oil change scams.

Friendly tip to everyone: take a photo of say (in this case) the radiator when you schedule a time for the car to go into the shop. Once you get the car back, look at your invoice and see what was all performed on your vehicle. If it was replaced, it should not look like the radiator in your photo when you first went to the shop.

If it does... beat someone's ass at that shop and tell them to fix it again.
