3.8 L Coolant leak
My 95 Bonne with 3.8L uncharged engine (90 k miles) is consuming coolant. No external leaks (hoses, clamps, core plugs, water pump, radiator, heater or overflow tank). Coolant side pressure checked hot & cold OK. Coolant sniffed for exhaust; none detected. Here is the crux: the exhaust pipe drips GREEN LIQUID. Engine runs fine (for now). Any comments would be appreciated.
Thanks Bumpa2 |

It's not going in the oil pan is it? Thats a weird one. Is your coolant the orange crap (dexcool) or green. How much coolant is it using?

3.8L coolant leak
I've used the green stuff since mile 1. No coolant in oil (drained and settled for separation). I read about several cases of coolant leaking into the intake via the upper intake manifold (black fiber or plastic) but I didn't think coolant actually circulated above the lower aluminum manifold.

Yeah we do keep those upper intakes in stock, cause they crack a lot.
I am pretty sure it has to do with coolant leaking. That would be a good place to look. |
