The only air flowing past the radiator is from the engine fan(s). Same for the A/C condenser. Especially bad in a hot climate. Hot air from the engine just circulating around in the front of the car.

Update - I couldn't find a real data sheet, but the John Deere product blurb says it's compatible with "most" other greases, so I'll take that to mean it will be OK with lithium type grease.

I got a tube of John Deere polyurea grease, part #TY6341, for greasing control arm ball joints. I used a lithium/moly type grease on them previously. Now I find that there's a difference between "shear stable" polyurea grease and "conventional" polyurea grease, where the shear stable type is...

That picture illustrates why I used it for only one oil change a few years ago - I could not find it in 5-qt jugs anywhere, so the total cost was significantly higher than alternatives.

I've been using 5W30 since owning a Taurus with the 3.5 V6, even though the manual and oil cap demand I use 5W20. This is a non-turbo, non-DI engine, it's very quiet and has been trouble-free, and is just now coming off the 6 year powertrain warranty. What I currently have in my "stash" is 2...

In defense of Ford, my 2015 Taurus with 44k has not been making any suspension noises whatsoever, even though the immediate local roads to go anywhere are extremely rough (really an understatement). It's about as smooth a ride as possible on these roads. It does not have a PTU though (for which...

Well changing the hoses would be way more of a PITA than changing the coolant. I used small diameter hoses + an fittings to replace original small diameter metal piping (runs under the intake) that was a problem, it's not the main radiator hoses. I used silicone just due to it's high heat...

I recently (a couple of months ago) replaced some hoses with silicone versions in an engine that uses dexcool. Now I'm learning that's a bad thing - the dex has 2-eha that will eat the silicone? Does this apply to any type of silicone hose? The hose I used has two layers, the inner is red, the...

I recently changed to Valvoline semi-synthetic 85W140 in my 20 year old Camaro with a torsen diff. The owners manual specifically calls for synthetic, maybe so they can spec a longer maintenance interval. Before that was using Supertech 75W140 to try to fix what I thought was noise from the rear...
