My top radiator hose (around the belt one) has a nick in it from the belt, and I am going to replace. My question is approx. how much ELC will I lose when I do it? I want to get some in advance and not sure how much to get from CAT. Thanks in advance!

 

I replaced mine a few months ago with the one that wraps around the belt and i only lost about a quart

 

Any idea how the belt nicked the hose? is it that close?
I attempted to install the around the belt hose on mine AFTER I installed the Dieselsite coolant filter setup, the hose rubbed the filter itself too close for my comfort so I went back to the through the belt hose.

 

Put a drain pan under the radiator and let some coolant out. No loss.
I zip-tied the hose to the support, fits great.

 

I believe my (around the belt) hose is against the filter, but I didn't concern myself about it. Its not like they are moving, is there an issue that I'm not aware of?

 

This is what I would do as well. Just drain some coolant into a clean container and then pour it back on when the new hose is installed.

 

Agreed with draining. I keep a clean drain pan just for coolant in the garage since having to fix the leaky thermostat housing like three times. Got good at draining coolant

 

My hose was rubbing my filter also so I put a thick piece of teflon between the hose and filter now I have no more rubbing. Reuse your old coolant that you drain out.

 

Do yourself a favor and install a dual-alternator coolant hose. This routes the hose around the serpentine belt instead of through it... allowing replacement of the belt without the need to remove the hose.

 

While you are draining the cooling system let the degas bottle act as a site glass. Watch the coolant level in the degas bottle. Once it gets about an inch below the the level of the bottom of the upper rad hose at the radiator stop draining.

 

My e99 came stock with one alternator and the around the belt upper hose. I have the dieselsite coolant filter that makes contact with the hose but no issues after 150,000 miles like that.

And NEVER, EVER leave a pan with coolant unattended where a dog or cat can drink out of it. It's a painful death for them.

 

Good point Andy. And small children may want a taste. Plus small ones can drown if they slip head first into a bucket with only a few inches of fluid at the bottom.

 

if you think some sediment fell into your drain pan,just filter your coolant through a paint funnel or a piece of screen of some sort.

 

My hose goes around the belt. Just replaced it in the Spring. I have a black tie wrap holding it to the support. I don't know what happened. The nick is running in the same direction as the belt. Maybe the hose swelled up is all I can conclude. Approx how much will I remove to drop fluid level to the thermostat level? Looks like the thermostat level is close to about the bottom of the degas bottle. I got a clean bucket but it is only about 2 1/2 to 3 gallons. Thanks!

 

Skip the wire tie and go with a metal hose clamp. The slot is made for it, and 200 degrees is pushing the limit for plastic wire ties.
