Water pump GRAF or GMB

Screw NAPA. Get a Meyle or Graf water pump, they meet and exceed OE standards.

Do you still have the original water pump? Those has plastic impellers that fail. Replace it with a metal impeller pump (Graf and Hepu are ideal).

I have a GRAF metal impeller water pump. so far so goof with it, i like it.

I've used GMB some 10+ years ago. They were made in Japan and came with a lifetime warranty.

Sounds like your water pump is shot. The impeller is spinning on the shaft and not pushing the water. I just had a customer who had this problem. The crazy thing is, I just replaced the pump about 2 years/30K ago with a GMB pump. He had the exact same symptoms as you: car gets hot, but does not overheat, no water through the return line, and fan takes a long time before it turns on.

Get a new WP with metal impeller, Hepu, Graf.

Just to let everyone know, it did indeed turn out to be a defective O-Ring on the Graf water pump I installed a couple of months ago.

all graf water pumps with metal impellers are tested and balanced before packaged so why would there be any reason not to buy them ?

My local aftermarket dealer stopped selling Graf water pumps after two bearing failures in the last month (one failure destroyed the camshaft timing belt).

My OEM plastic one broke and so did the metal-impeller Graf I replaced it with. They Graf seized up and leaked whereas the OEM plastic one just leaked.
