Will a hard run of this nature catch a BHG. i will also look for the erratic idaling and keep an eye on the temp gauge. Does anyone have any other idea's on what else i should look at. Your help is highly appreciated.
To safely do that you better have a whole day. Always wait a few hours before opening the radiator filler cap to avoid serious injury. Just ask to take it out for 30 minutes. If he/she declines, ask if you can let it idle for 30 minutes after it reaches operating temps. If he/she declines they're hiding something. It can take as long as 20-25 minutes to manifest an air bubble even under normal driving.
-Check the fluid before starting it up, if the engine is cold
-Run engine for as long as possible.
-Check for fan activation
-Check for overheating, even if slight, at or past the 1/2 way mark
If you're still not sure, get a sample of the anti-freeze from the radiator after it ran for a while, and send it off to a shop or lab to be tested for hydrocarbons.
