Confirm this is a water pump leak for me

James9100 · Oct 23, 2023

99% sure this is my water pump leaking but wanted to get a second opinion before ordering the pump and fan clutch.
Not great pics but should give you a good enough idea with the UV dye.

Could be anything above that including a hose, the thermostat housing or water pump.

Possibly considering I did just replace the housing and hoses, but directly under the housing is dry and where lower rad hose goes to the pump is also dry.
I wasn’t driving for it to be blown around a bunch either, just saw this while idling.

It's tricky to see. Could be the pump but that coolant has a funny way of running down places you can't see. I would suggest a pressure testing kit if you don't have one. You could probably rent one for free from AutoZone.

It’s directly under the pump so I really think it is, I’ve thought about getting a pressure tester but it’s really not something I’d use often enough to justify buying one.
We haven’t got AutoZone up north here, only free tool rental place is 45 mins from me so not very convenient.

Looks like a waterpump leak to me.

Your fan shroud is cracked too.

Lucky you.

Where do you buy your air fresheners?

His Predator graphics were more descriptive than yours. That Alien definitely has several leaks. Yours looked like purple paint.

Can you get your UV light higher up directly underneath the water pump where the weep hole is and take another picture? Can you smell coolant?

James9100 · Oct 24, 2023

I can’t figure out any way to spot that weep hole without first removing the water pump pulley.
Hopefully this pic from underneath helps a bit more, marked the water pump lower rad hose inlet for some context.

Bingo,this is how you see.it takes an hour r&r and a little elbow grease without costing anything

Ya my problem is it’s really already too cold to do any work on it outside and I have to have it in the garage for as little time as possible, basically just to do the work.
I suppose I could bring it in, take it apart, check the weep hole, roll it out, order what I need to, then roll it back in to do the work.

Was hoping the pics would give a good enough validation to be the pump though, on the other hand I could just replace it anyways and then I have a totally refreshed cooling system.
