i am dealing with a 1999 ford contour with a 2.0 liter engine.?

The manual is correct. The reason is that the alloy and machining process produce very uniform sealing, and media compression under all temperature conditions in thin wall Aluminum castings, and this is achieved during initial torque application. Short cut past all the know it all crew.

1.Obtain an unstressed bolt dimension, that is, the measured overall length of a new TTY bolt for that service application, or use a new one to side by side comparsion.

2. Measure the overall length of a stretched TTY bolt removed from that engine only. It takes minutes to wire brush all the non-bolt matter from all parts of the bolts. Do it.

3. Use a caliper to measure the overall length of each bolt, and a micrometer if you have one, to measure the overall diameter. Remember that a micrometer is used circumferentially while calipers are used to measure length. With a big hammer, deform the long ones after this so you won't be tempted to use them again in the future after you are done measuring.

4. Using only the ones that are the exact same length, measure the diameter of the narrowest part of shank on all of them; any narrow ones are garbage.

5. Now you have isolated the within spec ones. Buy a correct size metric bolt of the exact overall length and diameter if Godzilla is chasing you, but wait the two weeks to do the job right. Those are the ones you will use with your new water pump to keep from fracturing the water housing

As an aside, you tighten TTY's initial torque in stages with a torque wrench, and the final phase with a dial example"; 5"lbs, then 10"lbs, then 15"lbs, then 20 degrees using the prescribed tightening sequence. Do not re-torque. Follow correct methods and procedures, and you will have confidence in your work. Say good bye. Do not follow most of the advice given here. Most of them have never used a torque wrench, nor do they know how.

The reason TTY bolts are used is "Thin wall castings are used to save weight, and will be damaged using conventional bolts and torqueing methods

You should get the torque specifications from the dealer if you don't trust the information you have. The housing for the water pump is pretty flimsy/brittle. If you over tighten the mounting bolts, the water pump has a high potential of breaking/snapping. Go to this website and compare the bolts on the water pump to the ones on this website:

TTY bolts have the shank diameter smaller than the thread diameter

There are normally two specs given for some bolt torques. Cylinder heads being main example. Yeild factor is for fast and accurate machine builds or specialised torque meter that can see the yeild moment as easy to miss and over torque bolt leading to early failure.

Second spec is often slightly lower applied allowing sufficient torque but not optimal. This is normally given for hand torque tool single wrench method.

Main dealer can confirm and get info from manufacturer.

when you are replacing a water pump all you have to do is tighten the bolts with a ratchet and socket ! just take each bolt and tighten it so tight and do the rest of them the same way ! after you get all the bolts snugged up then go back over them and tighten them ! i changed several water pumps and new once used a torque wrench !

It's a frickin' water pump! Put the bolts in and snug 'em down. Sometimes you just have to use common sense and ignore what the 22 year old engineer with coke bottle glasses decided to dream up when he designed his little piece of the engine. Sheldon aint always right!

this one is a judgment call. water pump bolts should only be hand tightened as they require far less torque because they are not in a critical area of high stress. they can be reused but its your choice.

The best answer I can give you is that regardless what parts you are replacing on a car if it require torgue reguirments then you should use it. I t may be find now but under pressure you can have a big problem later.

I HAVE replaced a lot of water pumps , and if you use red permatex gasket maker and the bolts are in good thread shape don't need a gasket just the red sealant spread on good tighten good crisis cross pattern you good to drive have fun

there are tourqe spec for almost every bolt on the car, just tighten them like a normal bolt, and u dontneed to change them, just make sure they aint striped,and clean, the hole also,u may as well change the timing belt while ur in there, if u don't ur only lookin for head aches, specialy if it has a lot of miles on it.

No mention of TTY bolts on water pump in alldata or MOD
