I have a 1990 toyota4runner 3.0. i just changed the water pump and marked the timing belt location to the gears itself. however i think the gears turned on me so now it will hardly run. its not timed right. do i half to take the lower timing cover off and set this gear also or can i just bring number one piston to the top and then reset the two upper timing gears to their marks and time it this way?

You can do the correction at either the crank or the cam, I would recommend you pull the cover off completely and reset, then turn engine over by hand and verify marks are still lined up, check it twice before you button it up and restart the engine, that's what we professional tech's do.

Change water pump 1990 3.0 sr5 toyota pickup

Water pump is timing belt driven. Change your timing belt too. Drain the coolant/antifreeze and everything on the front of the motor has to come off. Make sure you have the timing marks lined up

Timming belt broke from water pump broke while driving car put new water pump on n timming belt but car doesnt start right plus shakes doesnt sound right 2001 neon dodge

Sounds like timing belt not on correctly. Check timing marks are aligned correctly when installing timing belt. This vehicle should have 2-3 marks to be aligned when installing belt.marks should be on cam gear/ crankshaft gear and intermediate shaft if engine is equipped with it.

Need to know how to change a thermostat on a 1990 suburu legacy wagon over heated an lost all my antifreeze an broke a fan belt

Doesn't sound good. Usually t-stat is on engine. Follow top radiator hose to engine should be located there behind a 2 inch dome attached by two bolts and radiator hose is attached to the dome.

Now subaru's can't handle overheating. Slightly hot as in got to red but shut off imediatly, will often blow the head gaskets. Got hotter than that will crack the heads. as in drove more than 2 miles near red mark on guage. or by adding water while hot also will crack them.

Broken fan belt? was it timing belt and bad water pump? if water pump age is unknown will need one of those too. and most likely timing belt and some pulleys.

Good news is you can't hit the valves with a broken timing belt on these cars. But the timing marks are confusing there are 5 or so on the center gear but you only use the one on the back of the pulley on a tab that is a straight line. Point it up at the mark as book shows. the other two marks are ok. Putting in the belt tensioner is testy so good luck.

Best price for all these parts are on E-bay You can save hundreds by buy the sets.

Hi, my 1990 Toyota Camry with 3S-FE engine noises on timing belt side recently. I got my timing belt and water pump changed in 2006 December. So far I drove the car around 50,000km. I changed my power...

I had the same problem in my 3sFE, I thought the same way you did, but it turn out to be the fan, check if there is any play in the fan, change it and your scrutching noise will be no longer there

How to replace water pump on 2000 volkswagon beetle with1.8 liter turbo engine?

The following steps need to be taken to remove the pump.

1. Remove the ribbed belt. Compress the tensioner and remove the belt. Remove the ribbed belt tensioner.

2. Remove the upper timing belt cover.

3. Align your timing belt marks. The following pictures are for the cam timing mark, the flywheel timing mark for an automatic, flywheel timing for a manual and the marks on the harmonic balancer.

4. loosen the timing belt. There is a 13mm head nut that keeps the tensioner in place. Loosen this nut and turn the tensioner clockwise to get come slack in the belt. You are going to need a tool to get tension back on the belt. I use the tool pictured (picture of how to tension the belt) but know of people using snap ring pliers to rotate the tensioner.

5. Slip the timing belt off of the cam drive sprocket and off of the water pump.

6. Remove the water pump retaining bolts pictured and remove the water pump. The pump can often be stuck in place. A screwdriver carefully used can help in getting the pump

7. Moisten the o-ring with coolant before installing the new pump. Install the new pump.

8. Install the belt and tension as shown in the picture attached above. Turn the engine over by hand through a full revolution of the cam gear. Re-check the timing marks. The marks will often be off, don't be discouraged by this, it happens to everyone. If the marks are off loosen the belt and slip it the amount of teeth needed to align the marks.

9. Install the items taken off during the removal of the pump, fill the system with coolant and start the engine. The system will pretty much bleed itself out as it reaches operating temperature.

When you change the water pump on a 90 corola 4-door sedan are there alignment marks to get the cams back "in-time" or is there a trick to it?

If you removed the timing belt to fit the new water pump then you have to reset the timing on camshafts/and bottom pully and ... the bottom pully has a mark on gear and casing and the KEYWAY should be dead straight up. and the camshafts have timing marks on the gears and casing behind the cover..
Have fun

There is no easy way, the water pump is driven off the camshaft belt, you must pull the timing cover to remove the belt, line up all the timing marks before you remove the belt, don't reuse the belt.

Water pump

This is one of the most frusterating things to do because of the very limited space inside the engine, but you will have to remove the radiator the fan blade, all the hoses, the balancer, move the alternator, remove the timing belt cover and all the serpentine belts, remove the timing belt "MARK THE BELT WHERE IT ORIGINALY WAS OR YOU WILL MESS THE TIMING UP AND POSSIBLY THE ENGINE!!!", Remove water pump the reinstall new one, the assemble everything back together!! GOOD LUCK ITS A PAIN IN THE @$$!!!!
