Hello and thank you for using JustAnswer. My name is \*\*\*\*\* \*\*\*\*\* I will do my best to assist you.. I help many customers, so sometimes my replies are delayed, I will respond once available. During this conversation you will be given an automated offer for a phone call. You may accept or decline that offer.I don’t personally offer this service so if you take this another tech may call.
Sounds like you have classic coolant leak, you will need to pressure test the system and follow the leak to the source, you may need to remove parts to locate the leak and also use a flex mirror or flex cam to spot it, you can rent the tools from autozone if you dont have a tester. Once you locate the leak and you have questions about repair, let me know, thanks!
