🔧 Honda Denso Radiator Cap 19045-PAA-A01 Review

The Denso Radiator Cap fitted my 2007 Honda Pilot perfectly. It should fit perfectly as Denso radiator caps are standard OEM equipment on most Honda vehicles, at least that's what I'm told.

Fits me! I had an undetectable coolant leak so I started with the cheapest option; this radiator cap. Replaced it before a 1500 mile ride and didn't lose a single drop!

Works as intended! Since my old one didn't work, I bought this one to replace it. I switched the black plastic connector from the old to the new one. This is pretty easy, so don't buy a plug unless the plastic cap is broken. Reuse the old one.

Doesn't fit my 2005 Honda Accord I4, Revain says it will fit but it doesn't, now I need one find that fits. To update. Depends on the manufacturer of your radiator you buy, Honda have two brands of radiator, Denso or Vale, this one will not fit Denso if it is Valeo. If it's a Valeo, here's part #19045-RAA-A51 and you're welcome.

I bought this because I was starting to leak radiator fluid somewhere near the cap and it was cheaper to buy a cap and try it than taking the car apart to see if it really was the cover or the cooler itself. There was a crack at the end just below the connector so this didn't fix my problem but it seemed to work fine and looked like it was OEM.

Fits my 2002 Civic with new Denso radiator which was also ordered from Revain. Except for the plastic trim ring (which can be removed and mounted on a new cover but is not required for function), the cover corresponds exactly to the one originally installed on the vehicle. My old cap slowly started leaking coolant through the gasket after 233,000 miles. Looks like I won't have to worry until I'm half a million miles away. It's so nice to have Revain Honda parts delivered right to my doorstep…

This is a Denso brand that does many OEM's for Japanese car manufacturers so I know I have trusted their products for years. This cover fixed my overheating issue in my civilian device that I've been trying to isolate for a while. The thermostat, fluid, hose and new fan switch didn't control the temperature in my civilian car and as a result I used a heater to keep it cool while in the car. The last step I had was the lid and another attempt to let air in. from the cooling system. The lid was…
