Replacing water pump 93 Toyota corolla?

And here I thought is was against the rules to pretend to be someone you're not. "Master Mechanic" indeed...

Regardless of the engine in your car (1.6l or 1.8l), the timing belt DOES NOT need to be removed for water pump replacement as it's mounted on the right side (nearest the firewall) of the engine. Here is a pretty good online account of how to do it.

Good luck. If you have any questions for someone who actually knows how to do it, e-mail me.

Hi,

No the timing belt does not need to be removed, just the "fan" belt though I doubt it goes around a fan these days as most cooling fans are electric!

When replacing the water pump there are a few simple things one must remember.

Loosen the alternator as the "fan belt" will go around the alternator, the power steering pump etc and the water pump. remove the belt and if within budget and or beaten up replace it at this time as well.

Remove the bolts for the water pump, use a nice sharp scraper to scrape all the old gasket off make the metal nice and clean. Take care not to let scraped stuff get into the opening (may want to stuff it with a rag) while cleaning then Remember to remove it before putting the new pump on!

Mount the gasket as per instructions tighten the bolts in the pattern given and slowly (at first a turn or so per bolt then later as it gets tighter just half or quarter turn per bolt as you tighten them down in an opposing pattern).

Reinstall the "fan belt" and tighten up the tension via the alternator and you should be ready for the flush and fill.

At the radiator cap, flush with lots of water to get the old coolant and what ever out of the system, after you have drained all the water out. (The radiator has a drain at the bottom that you open for the stuff to come out and drain). Remember do not run the cooling system fully dry while the engine is hot once the stuff is clear at the water is just luke warm as you are adding copious amounts at the top and the engine is at idle you can turn off the valve at the bottom use caution and make sure the water is not too warm to scald you. Then keep filling at the top till it will not take any more and turn off the engine to cool it down all the way.

Caution, even if you put the radiator cap for a minute or two while the engine is warm the system presurizes so be careful not to have a gusher!

Once cool or barely warm to the touch drain fully and close the drain valve. Add the new coolant (mixed or premixed) to the system, bleed the air out of the system else you will get a vapor lock.

Over the next few days of driving and cooling of the vehicle keep an eye on the coolant level and replenish in the plastic jar (overflow bottle) but only to the fill mark. If you over fill that bottle you will be causing the coolant to spill out via the over over flow tube while driving or when parket after a long drive.

Use gloves, eye protection and if possible face shield when working on radiator. No loose clothing or jewelery. Your local library should have a wealth of auto manuals for replacing the water pump.

on there you will need a new timing belt - tensioner and water pump. If you never replace a timing belt and are unsure how I suggest a shop because if incorrect the valves can hit pistons

No the timing belt does not have to be removed,

unsure of any online workshop manuals though.
