Water pump replaced on this 1.4 petrol Vauxhall Corsa D. Torque settings for water pump bolts 8nm. Hope this helps some of you out, don’t forget to subscribe to our channel for my how to videos! #waterpump #corsa #corsad
Fantastic video Tom - thanks so much for sharing your knowledge. The video allowed us to replace our water pump due to recent over heating breakdown. Thanks Tom 👍🏼
Tom, absolutely super video and very well explained. Certainly helped me to diagnose issue on daughters Corsa D (although a 1.2) but looks very much the same. Great work!
Mate I wish I'd watched this earlier I got stuck on getting the cover off and was conscious about jacking the engine up too far to get the bolts out. I watched a video from another guy but he had different mounts obviously off and older Corsa. Thanks for this I know I was on the right track.
How did it actually become apparent that the water pump was defective? I have just removed the same but unfortunately have not found any defect in the pump itself
Hi Wayne, i haven't had any issues removing the mount as yet, i'll lower the engine first to remove the bottom bolt and then jack the engine up to remove the rest. The exhaust flexi will stretch slightly but we haven't seen any exhaust issues afterwards as yet.
Thank you for this my corsa been overheating tried everything, ordered new therm didn’t work new pump on the way and a torque wrench hopefully it’s the pump, all pipes remain cold
@@joer2513 Are you sure the engine coolant physically overheats? (Steam out of the radiator cap?) Because a weak point with the corsa’s is a faulty radiator temperature sensor, you’re dashboard will show overheating engine and the engine goes into emergencyloop, mine did the same. Coolant temperature on the dash was 140°C but the engine was functioning normal, except going in emergencyloop, since the engine doesn’t know the coolant temperature. You have 2 coolant temperature sensors on the Corsa: 1 in the thermostat housing & 1 in the radiator. If the difference in the two temperatures goes over a certain tolerance, it trips a check engine fault code P00B7 (engine coolant flow low/performance) and/or P0117 (engine coolant temperature sensor 1 circuit low) Also are you sure the thermostat functions correctly? The plastic legs that hold the thermostat in place break easily wich results in an always closed thermostat. The thermostat should open at 103°C. From what I read its a problem with the radiator temp sensor or you’re thermostat. If the waterpump doesn’t leak or make a whining noise. You can also listen if the bearing is still good with a long screwdriver on the waterpump and listen, or a mechanics stetoscope. Good luck in finding the issue 👍

I cant seem to get the bottom bolt out of engine mount bracket if i let engine down it wont come out and if i jack it up the engine is caught on bulk head and wont go high enough, when jacking engine up it seems to go up and back.
Hi. Do you know what is a normal water tempresure for Corsa D? My corsa standing on driveway goes up to 117. The fan kicks in at 109. Shouldn't be normal tempresure at 107 for Corsa D 1.2L
ofcourse you mentioned that you supported the engine underneath but you had to show us this. This is the most important. Don't forget this is a tutorial video. If i will go my car to the workshop , your video is useless for me.
