I overheated around the freeway and was able to make it to an area car parking zone. I turned off the motor vehicle and found absolutely nothing in the way of what you would probably usually find In cases like this. The radiator hoses had been cold! So I opened the radiator cap and found nothing at all, no coolant? I authorized the car to chill after which you can added water to see if I could locate the leak. The car begun but was managing rough, so I hit the throttle physique to present it some fuel and it stalled. I tried to get started on the car again, and on the next attempt the car engine just stopped. Once again I looked for a leak and located practically nothing… Exactly where the hell did it go? Can you say hydra-lock? Following a tow household, I pulled the spark plugs and the water arrived out. In anxiety that I could have warped or cracked the heads, I began making cellular phone calls. I was not as well concerned about any serious motor harm, as the car wasn't underneath a functioning load on the time the h2o crammed the cylinders. Soon it absolutely was time to begin using the engine aside and investigating the extent of injury. When I pulled from the platoon I discovered the top 50 % of your consumption was full of h2o. The gasket around the EGR stem had melted the platoon and gasket and allowed the drinking water, I place in previously, to generally be pulled in the cylinders.
