Leak, passenger side windshield. (1 Viewer)

[SEAWOLF]

I’m wanting to replace mine. Had my screen replaced and the cowl was leaking. I put some plastic over the air intake and the flow is not great in the cabin. Going to remove the plastic and buy a new cowl, who’s got the best price?

Have you considered installing a U-shaped channel at the window to air intake edge, instead of a full cover to route any water bypassing the cowl seal sideways?

IMO it is worth having a secondary means to prevent water ingress as passenger side A-pillar has critical main harness electrical connectors you really never want to get wet.

Something like this, done with by "best" drawing skills in snippet... Way to fit it and interference with cowl to be looked at of course.

One of the best ways to early detect and avoid damage from this leak if it occurs is all-weather floor mats. Generally the leak will end up on the passenger floor mat making it obvious something needs to be done.

What is the correct part number? I pull 55708-60101 from partsouq with my vin and it's around $600 from online parts dealers. I found 55708-60091 in another cowl leak thread and it's about $370 from those same websites. Both are called "Cowl Top Ventilator Louver Sub-Assembly" and both are an "exact fit" when I put my vehicle info into the website.

The parts diagrams suggest the 091 number is "without (cold area spec)". All US 200s should have had the spec, but I'm not sure what would be different about the cowl.. the only kindof relevant thing I can think of is the wiper de-icers, but those are in the windshield itself, not the cowl cover.

If you keep digging in the search results from this section you'll see people that have tried a couple different parts. Maybe see what they had happen.

This, from personal experience.
