The funnel Im referring to is those spill proof funnels that help with bleeding the coolant... getting non stop bubble after like 25 min, even jacked the front end up to help, and yea I also used the bleeder valve on thermostat housing. Got the overflow out my spill proof funnel when shutting car off. Guess that part could be I used too much coolant, some have told me this is normal because the coolant heating up makes it expanded and without the system closed off it wants to overflow naturally, but this never happened with my 3.8 Buick when bleeding coolant...so it makes me think something is wrong
