You have 2 inconsistencies in your request. The Brand shows a 2005 Opel Astra 1.6 and you need to put it in the Jaguar brand category for more help. You then mention coolant leak, which is the term for Antifreeze in the cooling system. Later you say problem is the A/C valve. Sometimes it is easier to remove a larger part like the Condenser with the hoses attached by separating the ends of the hoses from their joints in places that are accessible. Then replace the components from the larger part, return the Condenser to its mounts, and reattach the lines at their joints which are accessible. You will need extra O-rings in some cases. Be sure to use green Silicon O-rings and have A/C tools on hand.

there's bolts behind the bumper have to get under the front end

Lots of problems with those roofs. Take it back to the place that fixed it and tell them to fix it properly. Probably air in the hydraulics. https://www.google.com/search?q=Opel+Astra+Bertone.+Message+%27too+slow%27+appears+when+trying+to+open+roof ..

Identical cold start issue on my Astra IE 1996 F series after the engine got rebored - after months the new oil pump was found to be faulty & clogged-up & replaced by the spares supplier - the car then ran perfectly after this. I was told the blockage created a backpressure & the computer was stopped it starting. 16 years later - 10 yrs after the last service covering just 8600km (last 2 yrs car hardly started) has identical cold issues again. It can be driven around & wont take long cold start in our warm coastal winters. The good mechanic seems to be giving up trying to fix my old car but refuses to believe its a low oil pressure issue saying that just makes the oil warning symbol light up & doesn't affect a car starting. I want to check if the engine warning light works on starting showing the low oil pressure sensor is working. But his now busy searching for a Astra specific temperature sensor.

Question edited for a lot more clarity, and sentences. Question moved to an Astra Category. All question need full 'year make model' please. That is a sorry tale. Some garages will disconnect stuff so you have to come back and they will dream up something else that needs fixing. All your issues are electronic and covered by the computer network that connects all the modules and sensors. There is only one way to diagnose those faults and that is by an auto-electrician who will connect a $5,000 scan tool computer and pinpoint where these faults are and fix them. They will often come to you. You can't guess faults like these. https://www.google.com/search?q=auto+electrician+near+me ..
