Radiator overflow, overflowing (3 Viewers)

[TheITGuy]

I've noticed my rig typically gurgles a bit after a drive on a hot day, but I don't have any overheating problems (far as I know) or any coolant leaks.

Reading through these posts, it sounds like the only time you've gotten the IR gun out was on a morning run when outside temps were in the 70s. Someone can correct me if I'm wrong, but the readings you shared didn't look to be too far off of normal operating range. I'd be curious to know what type of readings you get after a drive in the 90s?

Also, I would check your hose clamps and make sure they are all tight, especially around the overflow since that seems to be where you are losing coolant. Last time I had a leak, it was just a clamp that wasn't quite tight enough.

Find a steep ramp - park on it - remove the radiator cap, top off fluid - run engine for a while until you see serging/fluctuation in the level of the fluid - the thermostat is opening/closing. Clamp off one of the heater lines to the front heater for a few minutes - this will force flow to rear heater; move clamp to rear heater hose. Your cooling system should be bubble free. Put on cap, fill tank like 1/2 way. As the rig fully heats up, coolant will be pushed out of rad into tank. When it cools back down, fluid will be sucked back into rad if everything is working correctly.
