Hello, first post here, but I was wondering if someone had any advice for me.
I'm the owner of a 2016 Focus ST diesel and I can't find the issue with my car. Ill provide as much information as I can remember. I'm not very engine or car savvy so if I've done anything silly, feel free to roast me, I don't mind the banter.
It started 1 month after servicing this year. I usually only drive a very short commute but on this occasion I was traveling long distance down the motorway when the oil temperature started to rise. Moments later the water temperature shot up to max and went into limp mode for about 2-3 seconds before returning to normal with oil temp still high. About a minute later I get a red warning light to pull over safely. Luckily I was very close to a services so I pulled into there where I let the engine cool down for around 20 minutes before starting her up again and driving off. I drove home later that day, keeping a steady speed of around 55mph with the heaters on full blast and I had no issues getting home.
I checked the engine coolant later that day and it was almost empty. I just assumed the guy who serviced my vehicle had not topped up the coolant enough so I did it myself. A few weeks later my water temps shot up randomly again before quickly returning to normal. My coolant was low yet again. I took it into a local garage and told them I was losing coolant, later that day he called me and said he couldn't find a leak.
Today I had another longer than normal commute so I topped up my coolant and off I went. I checked my heaters 10 minutes into my commute to make sure they were working, but they weren't(water and oil were normal running temp). I pulled over and turned off the engine. Before checking my coolant I turned the engine back on about 30 seconds later and the heaters were working perfectly.
Later that day I topped off my coolant yet again before driving home, and yet again the heaters didn't run warm after 10 minutes of driving so I pulled over, let it run idle for a while and still no hot air, even though water and oil temps were normal operating temp. I let the car cool down for about 10 minutes and opened my coolant cap and coolant leaked everywhere. I thought maybe I just overfilled it. I drove about another 5 minutes and still no hot air. I let the car cool down for 30 minutes this time and checked my coolant, which was empty again. I topped it up, again, turned the engine on and started driving home. Heaters were warm this time, keeping a steady speed of around 55mph for the next 50 miles . Closer to home I checked to see if my car felt any different by giving it some beans and all feels good.
Sorry for the long post but I feel like it may help identify the issue! The garage I originally took it to seemed friendly and had good reviews. He couldn't find the issue, but I can't say how much I actually looked for it. So if anyone knows where to go next to potentially get this issue fixed I would be very grateful!
Many thanks in advance.
