my water pump is leaking just wanted to know if the pump uses a sealant or a gasket...

 

did a search but only helped to a certain point have a good water pump leak...
thanks guys

 

when you buy the water pump will you need to purchase a gasket as well..???

 

It actually uses an o-ring to seal against the block. I think the OEM pump comes with the 0ring. Check with Jeff at Champion Toyota in Houston.

Regardless of where it's leaking, either from the early warning seep hole or the o-ring. It's probably time to replace the thing. It's pretty cheap anyhow.

 

i bought an aisin (lexus factory) waterpump off ebay for under 100 brand new shipped to my door came with gasket too!!!!!

 

lol not to burst your bubble but I got the exact same pump on Amazon a few months ago brand for $50 with 2 day shipping included......sorry lol. All though $100 is a decent price if its the whole thing.

Sadly I have YET to change mine.

 

thanks guys those prices sound great
thanks for the help

 

sorry again guys but today while inspecting the car i filled up the radiator to full and drove around for about 5-10 minutes locally and when i got home it was was completely dry but yet the reservoir tank was boiling
does anyone have a clue about my sc..
thanks

 

Sound's like you have a massive coolant leak, and you somewhat overheated your car.

 

you sound to have a multitude of issues. Like Ryan said you have a massive coolant leak. I would start looking at the radiator and check the upper and lower radiator hose. If the water pump is leaking per your original post you are losing pressure in the system so the fluid is not recirculating like it should...which leads to the overheating.

However for you to loose the entire radiator in 5-10 minutes this is a leak that you will be able to spot quikcly. I would refill and look in the engine to see if you see a leak. If not. Turn the car on and see if the water/coolant is spewing out somewhere.

I would be amazed if you are loosing that much through your waterpump leak because if the whole is that big the pressure would not be there to circulate the water...I could be amazed though. My gut feel is that you will hear and see the leak with the engine off.

 

Look down into the radiator shroud with a flashlight, and check the fins/core. Your radiator could be coming apart under pressure.

You've got some issues..what you could do is fill it up with coolant, and let it idle. Watch the temp & the engine, and as the temp rises(dont let it go full overheated) you should be able to spot your leak.

 

looking for leaks hard to find no leaks in the entrance hose but hose is full and the return hose is just completely empty regardless of how much coolant I tend to put in

 

ok just few more questions I have a 95sc300 and want to know if it is the 10 or the 11 bolt water pump and is the water pump attached to my timing belt?

 

just need to find out if its 10 or 11 bolt??
