Leaking Coolant when Towing

1303 Views 3 Replies 3 Participants Last post by  bennetbr
I have noticed the last few times I have towed that coolant is leaking out the degas bottle at the cap. The dash temperature gauge hasn't changed and it doesn't seem to run wierd or anything. I don't smell fuel in the coolant so I don't think its a injector cup or anything like that.

Do I have a bad cap or thermostat? It only seems to be a problem when towing, never does it when unloaded.

Thanks

Any easy way to check the cups without tearing the engine apart? I noticed that it only seems to spill over after I fill it up to the fill line on the tank. It will spill out once when it gets a little hot when towing then doesn't do it again. Seems like a injector cup would pressurizing the cooling system all the time.
