Hello all.. 1st time here.
We have a 2005 Odessey with 108,000 miles. Timing belt was changed last year, as well as heat pump. My fiance mentioned to me that the heat wasnt blowing hot air the other day. So, I went to investigate. Upon checking for fluid in the radiator I noticed the coolant was light brown. 1st thought, oh crap, I took it to Firestone a month ago for an oil change. They put the oil in the radiator... Anyway, So, I drained radiator (not flushed). Refilled with water, and started the van. Water stayed clear for a bit until Im guessing thermostat opened. Then I saw the light brown floating around in water. I thought maybe that was some left over oil mix because I didnt completely flush. Then, I saw a darker oil (fresh) Im guessing.
So, Im not sure exactly where the oil is coming from. Is it a leaking head gasket? or is it an oil cooler leak? Not sure. The van has not smoked, and there is no sign of the carmel looking gunk in exhaust pipe.
When I 1st looking into fill plug of the engine it looked like some of the same (light brown) in there. But now that I have ran engine, not seeing it.
Anyone else had this issue? When I talked to a mechanic (x2) they didnt seem to think the gasket was leaking.. but to me, seems possible.
I am planning on taking it to a shop tomorrow for them to take a look.
If anyone has any knowledge, I would greatly appreciate it.
Thanks in advance,
