I would be swapping out the radiator on your pilot. Not sure if the Pilots had a revised radiator design in later years.

I have heard of one replacement by insurance, as the driver got lucky and the shop “sold it to the insurance” as it was an impact which took out the radiator

Over 14 years hear, never heard of anything from Honda Care or aftermarket warranty coverage handling the issue.

Piloteers community may be able to advise on you that. As far as the Ridgeline is concerned, nope.

Update- I took it to the dealer and they said they will not replace because it is rusty but they will replace if it broke off tho. So i said great will you replace my transmission too?

Huh? That makes no sense. A dealership told you they will not perform a service you requested? o_O

I just purchased a 1-owner 2007 RTS with 185xxx miles. It just had water pump, timing belt, tensioners done. Everything seems to be in great shape but of course anticipated the radiator might not have been done yet. It looks original to me (correct me if I'm wrong?) so I'm planning on replacing it at a shop. Is asking them to order the OEM Denso still a recommended plan? Planning on driving the truck low miles per year as it is a 3rd vehicle for us. It needs new tires, but any other items I should ask the shop to do at same time (was thinking spark plugs)? Pictures attached (1st is driver side and 2nd is passenger). Thanks...Excited to own an RL!

It definitely looks like you are running on borrowed time with that radiator. When you get the spark plugs changed you might ask about a valve adjustment, if you are heading abnormal noise from them. It's always nice to read about owners who are doing the proper maintenance on their vehicles.

@Matt77 , it looks fine to me.

@haymaker18 , you may want to look at a new radiator soon. those fittings are rather very corroded. Do not get hung up on who makes the radiator. I run a $100 TYC for 2.5years and it is just fine for the NJ snow and road salt. Just make sure you keep up on the maintenance of your truck.

And regardless whether the valves seem noisy or not... maybe especially if NOT... have the valves adjusted routinely. The exhaust valves tend to wear into the seat which reduces valve lash creating tight valves. Tight valves can burn and IMO, a tight valve (no noise) is a worse case condition than a loose valve (noisy).

I do the valves every TB/WP service.

Thanks to the advice on the forum, I got the valves adjusted, the new radiator in, spark plugs replaced, oil changed, tires rotated, fluids checked/topped off and a more thorough inspection since I had another mechanic look at it kind of quickly before I bought it. They also replaced the air filter and the cabin air filter as they were pretty filthy. The only thing that they found was that it looks like I have a slight leak in the axle seal, but they didn't seem very concerned about it (just that we should keep an eye on it). The shop tried to buy the vehicle from me on the spot, so I'll take that as a very good sign that I have a nice RL, given the higher miles. It runs and drives like a dream!

For slightly rusted washers I was thinking of hitting the washers with a product like Eastwoods fast etch which would dissovle the rust then hitting them with a rust inhibitor, what do you guys think? Not sure if the fast etch would would be too harsh and actually eat away the washer tho? Thinking The rust inhibitor should not be an issue.

Off course this is just temporary untill the nicer weather rolls around so I can replace the radiator.

The fitting will actually rust off from the inside, so I don't think the Eastwoods product would be too beneficial.

Thanks to all who have provided their thoughts on this topic. I check the trans fittings on the radiator on my 2006 RTL with 103,000 miles, and while I didn’t see anything alarming, I decided to install a new radiator just as a precaution. I bought the new Denso from RockAuto ($179 including shipping).
A very detailed uTube video is available so after watching carefully several times I was able to replace the radiator in about 4 hours....and I’m slow! I also used Honda coolant.
I then inspected the fittings on the old radiator and found a small amount of corrosion inside. They may have lasted for many months and miles but now I should have no issues for much longer.
Thanks to all again. I would not have known about this potential problem without this forum.
