My little beater 92, 22re with 5spd.
Sitting in a drive thru this morning, 80ish was outside temp, started getting a whiff of coolant, looked down and my temp needle was up over half way (normally runs very low...needs a sensor I know). Had been sitting idle for 15mins, no AC on. Being up that far was it getting/reading hot....soon as I pulled away from the window, the clutch kicked in and the fan came on, and needle slowly dropped. Popped the hood and it had pushed a little coolant out around the cap...not sure why there instead of out the overflow tank. Anyways, after cooling all afternoon, I pull the cap and start it. Coolant immediately gets foamy. Idle her up, and it starts moving across the radiator (left to right if standing in front) quite quickly. Back to idle, level comes up slightly but stays foamy, and doesn't move through the rad much at all. Seems the water pump is indeed working. When I first cranked it up, there were some bubbles which concerned me a bit...now I'm wondering about a partially blown head gasket. Truck has seemed sort of sluggish lately, but doesn't seem to burn any coolant. Been driving my big truck a lot lately, so going from a 500ish hp truck back to the little 4 banger could explain why it feels sluggish. Going to drain the coolant, flush and refill later in the week when I have more time. But what do you guys think? Fluke, or should I start considering a blown HG? Any other ways to test besides the bubbly coolant? I'm a diesel guy....haven't fooled with gassers much in quite a few years.
