Ford, Subaru and Nissan Water Pump Design


Jeff Matthews

Recommended Posts

Our Highlander was like this.  Had the water pump fail on me on a 0F degree morning.  Noticed the heat went away and then looked at the needle rising.  Pulled over and got a tow. 

 

It didn't cause the timing to slip, however, if you're clueless and keep drive, yeah, it's done... But same with overheating. 

 

I'm just glad I had the car that day and not my wife, since it was hers.  She would have cooked the motor or introduced some valves to some pistons.

How is it different from a timing belt on an interference engine?  Just make darn sure you maintain a good belt.

it's not

Replace the timing belt at the recommended interval.   While you're there put a pump and all the pulleys in.

especially on an interference engine

lets see..new timing belt every 40K miles or new engine every 45K...hmmmm...that's a very hard decision to make.

No.  I've tuned a lot of Subarus and had an STi for 10 years.  The water pump is not part of the timing belt tract on the EJ motors.  I haven't looked at the FA motors, so I can't comment on them.

Normally it's 60k minimum.

I stand corrected about the amount of miles, but I hope my point is still understood by others. I have a '90 Bimmer (love that car) with an interference engine. No way I am taking the chance of not replacing the timing belt at the recommended interval.

Yep.  And don't forget if the miles are low there is also a time interval.  I would not go past 5 years.  E30's are great cars, but keep up that timing belt!

I noticed in the picture that the don't use spring loaded gears as tighteners but long plastic looking dinguses.

There's normally a tensioner on one end or the other that keeps the chain tight with an actuator that works off of oil pressure.

Mechanic talk is fun, but the work sucks badly.  The guy in the video is a long-time car guru personality.  They'd have his arse if what he said was bunk.  He makes some pretty strong statements.  

Never watched it.
