Water pump OEM Toyota or GMB
Reviews
GMB is a decent pump.
Pros: decent pump
I replaced both mine and my dad's with GMB. Mechanic recommend it too. So far so good.
Pros: good performance
Had a friend rebuild his 22RE, guy ordered his parts from eBay. Parts to replace which I believe is a must, water pump, t-stat, oil pump, timing chain and tensioner.
Pros: parts are a must
I have their water pump on my Rx7, it's been A-Okay for over 3 years.
Pros: A-Okay for years
Vehicle:
Mazda
Excellent time to learn to do it yourself and buy a $65 water pump and timing belt kit. Dirty cheap for the miata. Just find a kit with a GMB water pump and a name brand belt.
Pros: dirty cheap
Vehicle:
Mazda
Over the weekend this is how I did the water pump. I didn't have 2 hydraulic jacks, so I had to come up with some other idea. When I took out the water pump, I think the seal was starting to leak. Cleaned up area and reinstalled with new water pump.
Pros: new water pump installed
Cons: seal was starting leak
I've used GMB some 10+ years ago. They were made in Japan and came with a lifetime warranty.
Pros: lifetime warranty, made in Japan
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.
Pros: customer had same symptoms
Cons: pump replaced 2 years ago
Mileage: 30000 km
Melling and Aisin are both premium WPs. Airtex is pretty good. GMB is ok.
Pros: ok quality
I put in a GMB in my '02 two years ago, and it's leaking already.
Cons: leaking, short lifespan
