Hi All, My question is simply this. Without taking anything apart..... Can access to observing the condition of the water pump weep hole on a 5.0 naturally aspirated engine be accomplished from the top of the engine or best from the bottom. I'm planning on going down to my Independent shop to look at my water pump before taking it to Jaguar next week. I'm sure he'll be using mirrors to look at it. Thanks all.

 

I did it using one of those inspection camera's with the flexible fiber-optic .

 

Yes, I've thought of that, but my Indy is old school.

 

Just take your smart phone record video and stick it down there,
works like a charm.

 

Took to Indy. There was not enough room to see the weep hole with mirrors. We did see what looked like a coolant stain drip mark on the housing or a tensioner. Could have been and older stain. Can’t tell with certainty on part it was on. I do believe the pump is new as it looks newer as well as the surrounding screws for the air intake etc look as if they’ve been torqued. I’ll relay the info to Jaguar on the day I brung it in.

 

Did the tiny plastic tube that fits on the front of the pump get replaced with the pump? It’s a separate part and cost BUT usually leaks if not replaced with the pump...ask me how I know...

 

Probably not Jhammer. You have an 08 which should be a different pump setup anyway. There were two part numbers of replaced parts. The pump, AJ813909 and AJ811539 (seal)... That's it.

 

There’s 2 more parts that needed to be replaced, the oil cooler tube that fits on the back of the pump and the little plastic tube that fits on the front of the pump. Very common for these parts to have slow leaks and the oil cooler tube is buried so you can’t see it leak. When I had a new pump fitted last year the cooler tube was replaced but apparently the dealer didn’t do it correctly and it leaked and had to be redone a few months later.

J Hammer. Yours is a 4.2 and supercharged. I’m fairly certain that’s a different set up for your water pump than for the 5.0 naturally aspirated.

 

I wasn’t referring to the 4.2, I was referring to the 5litre. Check the part numbers I posted up, you needed them when the pump was replaced.

 

Thanks....I'm sure they WERE NOT replaced. I'll mention it when I bring the car in to make sure they are looked at when the system is pressurized. The only advantage I might have is that the car only has 13,000 miles on it.........if that helps or not.
