Alternator , thermostat water pump replacement

[Toolaholic]

Here’s some pics of my Yaris under the knife

[Toolaholic]

Last pic was Chapman driver (that fits) removing philps screw on a/c line support that when bolt underneath is removed it can moved down out of way

[Toolaholic]

Armstrong 11-994 ratchet 3/8 to 1/4!adapter 14mm socket lower alternator bolt. Upper is 12mm

[Toolaholic]

No room to pull lower alternator bolt out with ratchet so I used a 14mm locking flex head wrench angled to fit between alternator and a/c lines.

[Toolaholic]

Alternator out there’s your water pump

[Toolaholic]

And the thermostat housing

[Toolaholic]

Note the rusted nutin last photo .Whole stud came out with but seized to it. Bought a new stud and nut.

[Toolaholic]

Use hose clamp pliers on lower road hose to thermo housing

[Toolaholic]

Hose off.

[Toolaholic]

I pulled thermostat out with a hook and pick

[Toolaholic]

New Thermostat and o ring. Out new stud in block with stubby 1/4 ratchet and 4mm socket. Cleaned housing with acetone/rag. Nuts are 10mm. Reassembled

[Toolaholic]

You should remove water pump pulleys bolts with belt on. I didn’t and put a 9 inch 1/4 extension to prevent pulley from turning. Scared back of pulley a bit. I used a new pulley so wasn’t concerned .

[Toolaholic]

I removed 10mm water pump bolts/nuts with a 8 inch matco 1/4 drive ratchet . Lowest bolt is near the hump in pump at bottom. I accidentally removed timing cover bolt that is very close to water pump bolt.

[Toolaholic]

Removed pump. Far right is bottom bolt hole that’s hard to tighten and close to timing cover bolt . Note dried pink coolant

[Toolaholic]

Tightening stud . Pump has 2 studs with 2 nuts and 3 bolts.

[Toolaholic]

Used permeated gasket remover and a razor blade at 90 degree angle. Ended up massaging goo gone oven cleaner on timing cover with m thumb 3 times . Throughly rinsing with water .

[Toolaholic]

Install new gasket and pump . Tighten to 11nm or 97 inch lbs. I used 100 inch pounds. Shown is gearwrench torque wrench between pump and firewall. The back nut and bottom bolt had to be done leaning on engine cover torque wrench towards firewall.

[Toolaholic]

Before torquing I tightened with little 3 inch tekton 1/4 ratchet. Then final torque with torque wrench

[Toolaholic]

Then put pump pulley then alternator on. Final tightening pump pulley with by on. I will ass a few more pics later .

[Toolaholic]

Photos of how to pry alternator . Pry alternator til it hits adjustment mark made with a Milwaukee jobsite marker. Tighten 12 mm bolt with right hand while holding pry bar/ alternator in place with left hand. Pry off motor mount as shown

[Toolaholic]

12mm Wright ratcheting wrench on alternator tensioner

[Toolaholic]

Torque specs : 14 lb ft alternator tensioner
40lb ft alternator bottom bolt
11nm 97 inch lbs water pump bolts/nuts
13nm 115 inch lbs water pump pulley bolts
9nm. 80 Inch lbs thermostat housing

[Toolaholic]

Couldn’t fit a torque wrench even with a crows foot or torque adapter on water pump pulley . Tightened with a 0 offset hazet 10x11 TIL pulley moved and slipped belt .

[Toolaholic]

The gasket scrapers. A razor blade at 90 or a SK gasket scraper with my thumb on top so it stays flat .

[Toolaholic]

I replaced factory hose clamp with a work drive clamp. It was hard to get back on thermostat housing even when compressed all the way with hose clamp pliers .

[Toolaholic]

I used a asin water pump and gasket. Genuine Toyota thermostat o ring. Stant thermostat . Had alternator rebuilt at chestnut hill electric for $108. It got new brushes , bearing and voltage regulator.

[Toolaholic]

10mm deep socket , 1/4 drive tekton ratchet negative battery terminal

[Toolaholic]

Due to close proximity of fender, it takes some maneuvering to get alternator and water pump in and out but definitely doable.

This looks like quite a bit of work! Gosh I miss my old Skoda 105, I could change this in 5 minutes there!

Wasn’t too bad. Had to finagle water pump and alternator in and out. Thin head ratchets helped a lot. It was very hard to keep socket on lowest water pump bolt when torquing to spec. Plus it was a pain scraping the minimal rubber gasket residue off due to tight quarters .
