Sup Mod keeping the peace
After the engine is fully warmed up and has been running for a while, shut the engine off and feel the lower radiator hose. It should be hot; if not, the radiator is most likely plugged up. Also when the engine has cooled down, start the engine up; remove the radiator cap. Insure the coolant fills the filler neck. Now look for a continuous showing of air bubbles which indicate a head gasket breach. You can also perform a radiator pressure test with a tool for that purpose; pump the pressure up to around 20 psi. It should hold for a long time; if it drop off quickly in just a minute or so, there's a breach somewhere; most like the head gasket.Took it on the highway just now to see if the bleed did any good, no joy. Overheated pretty fast this time. Turned the heater on and noticed cool air coming through, I increased the revs and hot air started. Could be a blockage? The sound of water swishing is present on startup, very little white smoke now. Could’ve been coolant residue from the 3 coolant flushes. Anywho I’ll ask for an actual leak down test or refund tomorrow.
