Changing the Water Pump

Hey friends,

I am going to be changing the water pump this weekend. Is the anything I need to look out for? How hard is this to do? Any advice is appreciated.

Ya need RTV and pipe sealer if I remember right. I'd open the box and read the instructions so ya don't find you're without something you need once you get started.

make sure you clean the block GOOD remove all the old gasket and make sure the metal pipe that is on the waterpump is good when i did my waterpump i replaced mine it was about $13.00 from the dealer it mite have a lot of rust, if it is rusty i (my opion) would replace it is worth the $13.00 insurance i was afraid it would leak it had a lot of rust on it it took me 1 hr once you remove the fan shroud it is easy

I just did this last week. Its not too bad as long as you don't have a problem getting bolts off. You do need to remove the power steering pump and the pump mount to get to the water pump though. There's no need to disconnect the hoses though, just kinda move everything out of the way. I got it done in a few hours with no major problems. I also replaced that heater hose pipe that 'my litte red YJ' referred to. I'd also recommend flushing out the coolant system before you take anything apart so you don't have to deal with coolant while you're under the hood.
