My upper rad hose is leaking at t stat housing oring. I have to switch to the new hose. I literally just did a flush and fill with cat ELC. Do I have to drain my coolant to swap the hose out? I also am d'leted so no e-gr coolers to get in the way. If I don't drain the coolant how much will I expect to lose upon disconnection?
2. Does the rad hose come with the o-rings ready to snap in or do I need to buy anything else?
3. Will I have to burp cooling system or does the air self purge?
