Rust on Frame with A/C drain mod fix

Did mine today after putting on my trd skid plate at my buddies shop so I could use his lift. It takes 3 minutes when yah got that big boy

 

I smelled the coolant smell the other day while offroading. I mentioned to the fiance if she smelled something sorta sweet, and she said yes. I told her that specific smell she is smelling is coolant, so looks like ill be doing this mod myself. Currently 6,000 miles so best to do now.

 

Coolant shouldn't be dripping from the hose, only condensation. If you're smelling actual coolant, you may have a different and larger problem.

 

I thought he may be in the wrong thread or something. Coolant? Huh?? Yes I agree with you, vike.

 

Haven't inspected yet if this smell is coming from that particular hose or not, but the aroma is there. I recall reading a thread about some small coolant seeping through some sort of seal.

 

Do you just pull out the hose or the whole rubber piece? Just hang it out?

 

The 5/8" heater hose goes over top of that. Dont pull the smaller hose sticking out too much!

 

FML Thanks for your help man! Heading back into the garage.

 

I live in NJ - cold - salt - rust - wonder if I should do this ? Could freeze up when the defroster is on because that puts AC on too. Where do you live ? Did you decide to do it ?

 

A/C will be on when defrost is on.

 

Just did mine. Thanks OP. Spent more time debating which exit location to use than doing any actual work. Ended up with the OP’s pick, there is a circular indentation which fits 5/8” heater perfectly.

Didn’t have any trouble with the upstream connection, no lube needed.

I’ll make a note to check on it in a few weeks in case it moves around on me or I didn’t get the clamp tight enough.

 

I never ended up doing this for the 2 years I had a Tacoma, moved onto a Tundra. I live in Iowa and its gets cold, this and the salt use in the winter, this is the least of my worries for rust.

 

I didn't see any reason to do this mod because if I use my A/C it smells like cow shit. So I don't use the a/c on my truck at all. Sure gets hot in this fother mucker during the summer months.

 

Something might be wrong with your A/C if it smells that bad? Or maybe something died in there?

 

The 2016 Tacoma I had it had the same issue. I don't drive long drives just in town on short runs.

 

Does anyone know if this is an issue on the 5th gen 4runners? If so... same mod with slightly different routing I assume?

 

What diameter hose are you guys buying, 5/8"?? Does existing tubing slip right in??

 

Love this mod! Told my buddy about this an he’s doing the same, thanks!

 

it fits, but it's snug. you'll have to shimmy it in to make it fit.

 

I did this mod today and have a question if anyone wouldn’t mind answering: I ran it as shown in the pics and realized afterwards it may have not been a good idea to have it in the wheel well. I think it’s okay, but does anyone think the tire may rub the hose? The first pic is with the wheel turned all the way.
