OK i searched and didnt find anything . since it has gotten colder out Ive had to use the heater now. When i first turn it on i get a Strong smell of Coolant inside the cab it goes away after about 20 secs. then i still smell a slight bit of coolant. Ive checked the radiator and expansion tank they are both full . What would cause this ? I had this happen on an Older Vw i had but dont recall what the cause was ...

THanks in advance.

Leak in the heater core?

 

I don't really know, but maybe you're burning a little bit of coolant. That would most likely be a blown head gasket if that was the case. Not saying you're leaking it though.

 

I think a head gasket you would smell it all the time but check your oil for coolant/coolant for oil, you don't want to blow the engine.

 

Yeah you probably would smell it all the time if it was a head gasket. Heater core sounds more like it.

 

Mine does the same thing, has since I bought it. No leaks on the passenger floor, and it goes away after a few seconds, so I havn't even bothered with checking into it toodeeply. I don't loose coolant, and the heat works great so....

 

If you know someone or a shop that has a CO sniffer, you may be able to verify if it is a head gasket. When I blew mine I was able to sniff CO in the radiator when the cap was off, confirming that the head gasket was leaking and exhaust was getting into the cooling jacket.

 

No coolant in the oil and no oil in the coolant, it doesnt blow white smoke either out the exhaust. Nor has it lost any coolant out of the radiator and the passenger floor isnt wet so I duno ...[&:]

 

You may have a small enough leak in the core that will give you that great sweet smell but not a big enough leak to get the floor wet. It may be small enough that you are dripping out the drain. Getsomething flexable like a pipe cleaner, put it in drain (make sure it is long enough) and move it around in there. If it comes back looking green or wet, there's your problem.

 

It's been a little while since ive been on work load is biting me in the bum. Anywho My truck is in the shop getting the heatercore replaced that decided to blew and spew coolant onto the floor. ugh LOL . SO hopefully tomorrow i will have my truck back and ready for a road trip to Wooster Ohio to pick up my new toy
