So I smelt a hint of coolant today and I went and investigated. This is what I found. Am I looking at a major problem or is it a easy hose swap. Kind of looks like the hose clamp is cutting into it. Will look into it further tomorrow. Figured I'd ask the experts here on the forum. Thanks Stev-o

 

That hose going into the valve cover is a vent tube not a coolant line. It looks like you have a leaking valve cover gasket to me.

 

Ok thanks for you input.

 

Youre valve cover gaskets are leaking but you need to find out why you smell coolant.

Pressure test the cooling system and look for leaks. If you can smell it, it is leaking.

 

go do a pressure test on your coolant system. If you smell coolant there is a high chance you are leaking. Could be something as simple as loose clamp. but you need to find out before it turns into something bigger.

 

Pay attention to your throttle body heater and lines, which are above the location you photo'd. X2 on snug up valve cover gaskets.

 

Thanks gents. I will have the system tested asap. Also will check the bolts on the valve cover.

 

x2 on throttle body... its right above that side. that should be easy to find if you let her idle a bit

 

Just look around the throttle body and if you seen one drop of coolant that is most likely your leak. You can easily block it off. There is no need for it unless you live in an extremely cold climate.

valve covers: be gentle, do not over tighten.

 

If your coolant level in the coolant bottle is not going down then that is a good sign.

A small coolant leak is not the end of the world, but you want to be careful to assure coolant is not going into the engine oil or into the cylinders.

Coolant which ends up in the oil ruins the engine bearings.
Coolant which ends up in the intake and into the engine can eventually ruin the catalytic converters and the O2 sensors - all 4 of them.

I know this as it happened to me and our Discovery I in 2007 or so.
