I love how easy these cars are to work on! It drives me crazy how many newer cars have water pumps behind the timing cover...unnecessary in my opinion... Great details, thanks for sharing!!!

For sure. Honestly, the biggest worry on a old 5.0 like this that has been sitting around is snapping off a bolt in the block. I really do think you are best to use an air impact set on a low torque setting for stuff like this because in my opinion it is actually easier on a seized rusty fastener than the continuous torque you apply with a hand ratchet, even a 3/8” drive.

Just changed mine, what you said about the fastener is not necessary true. I don’t have a lift like you and I could go underneath but I did everything from above and the fastener pointing up like yours had it was perfect. Take pictures before. Thanks for sharing 👍good job

The real key is to pay attention to how you put the hose clamps on so that they aren't too awkward to take off next time. Thanks for watching!

I total expected a bolt or two to break but glad they didn’t. I did this last year and broke three. But 2 of them were from the timing cover. Great video👍

Yeah, it’s a real possibility with these old cars. Like I said, I think your best chance is an air impact that is turned down. A penetrant like Fluid Film is a legitimate help, but it will never get at the threads in the block on this application. It can help if the bolts are partially seized to the pump housing though.

Great videos as always. Is there a specific brand of water pump you would recommend?

I bought a parts store special. It’s supposed to be high volume. They aren’t a complicated part so I think you probably ok with virtually any new service replacement part here, especially on a stocker like this car.

No gasket sealant on other gaskets between pump and plate?

Thank you. You mention using Fluid Film. I thought WD-40 was considered to be the best thing in the world for that. Am I behind the times?

If you have rusty fasteners that you are trying to get apart, in my experience fluid film is about as good as it gets for a penetrating lubricant. That doesn't mean that horrible fasteners come apart with one squirt of fluid film, or that it will work at all, but I'd use it over WD-40 on rusty fasteners for sure.

My 1986 GT 5.0 just started dripping coolant at a pretty good rate, even when the engine is not running. I looked underneath and under the hood, but cannot see exactly where its leaking from, other than its in the vicinity of the water pump. It's not from a hose. I imagine I'll find the leak once I start dismantling. I've owned the car for 11 years, so I know the pump is at least that old...it could be the original. Someone suggested it might be the seal instead of the gasket. So I'm wondering if I can just replace the seal instead of the entire pump.

It's probably more cost effective to replace the pump than try to rebuild it. Identifying the true source of the leak is the first step to sorting out this problem though.

Hi great videos 👍🏼, how to tell if the water pump is bad? Thank you

@tecmotiondyno Жыл бұрын

In this case it was straightforward because there was a lot of play or deflection on the shaft. Usually the issue is noise, shaft deflection, or leaks.
