I have a 99 til 137000 miles. It began running hot. I noticed water pouring out from behind power steering pump. I was thinking water pump but I then got to working on it and now notice the only time its losing coolant is when the radiator cap is on. Any ideas?

 

when was the last time you changed the water pump?

 

I bought the car from an older lady about a year ago. I have not replaced anything and I doubt she ever did. Car sat undriven for over a year.

 

it needs a water pump and probably a heater core hose,,maybe more

when the rad cap is on the pressure inside builds to its correct 14-16 lbs
That raises the boiling point of the fluid so it works better-protects longer in overheat situations that occur when water pump fails or cooling fan sensor doesn't turn on fan,or rad clogs

that wp job is due at 7 years/105kmiles--then every 7/100
Coolant needs to be changed every 5 years- its additives go bad
Cars that sit allow rubber parts like wp seals and hoses to rot away
Same with the timing belt, but those jobs are one behind the other so always do them together

If you can DIY - ck our section, otherwise expect rather shocking news~

 

the good news is with some basic maintenance parts and dollars- we can help you have your baby running smoooooth

the 99 4 speed trans is extremely reliable= excellent news

2 repair notes- ignition switch back- the electrical part, and egr system cleaning INSIDE the intake manifold- easy diys

 

replace timing belt and water pump and all of its associated pulleys

 

I would highly suggest to replace the thermostat as well.

 

the words poured out have me concerned its more than the weep hole on the wp

Have you used a pressure tester?? available for `free loan` from any major parts store
That pumps the cooling system up to 16 pounds so you can spot the leak

pouring would mean larger hole ie: maybe a hose blown!
without a known maintenance history you have to start looking at things like bolt heads on plastic covers- ever been touched by a human using wrench?

 

He's saying behind, and that has me confused. There is a coolant pipe below the lower intake runners, just a thought.

 

Basically what we are all saying, Prepare to lay down at least 500 bucks if you cant DIY, or 250 if you can.

 

The water pipe is right by the knock sensor, I've seen them rust and leak or the seal may have given up.
A video of it might help determine where the leak is coming from.

The pressure test is the way to go, Good idea to test before you buy parts.
Not going against the water pump here.

 

I agree it may be an actual coolant pipe-
as the words POURED OUT have never been uttered regarding a weep hole/water pump seal leak

any big name parts store will LOAN you (with refundable deposit so its not accidently forgotten in someones garage) a pressure tester
Goes on where rad cap goes and pump pressure to 16 psi (normal operating pressure)
watch for leak!
