O/t Cool S-10

Todd O. Cronkhite Maine Native in FL. Exile :~(

>Alrighty than. finally I have gotten to the bottom of why my S-10 temputeure guage was pegging out after driving for just a few miles.

First however a re-cap.

Temp guage pegged out to it's max of 260 degrees while driving at highway speeds, and dropped down to a decent temp while driving slower.

-I changed the thermostat--no fix

-coolant and it's level was good

-no signs of leaks or colapsing hoses

-Fan was tight on it's shaft

-Oil level was right

-no "milk in the crankcase

-no bubbles in the radiator

-no foul smells

-motor running smooth

-changed the temputure sensor-no fix

-flushed the radiator-no fix

-looked in radiator to see if water was circulating. It was.

-took upper radiator hose off of the radiator to check for output. Looked good to me

-installed new radiator cap-no fix

-got mad and took it to my mechanic

HE:

changed the fan clutch, declared it fix,and charged me $167.

-Drove it two miles, it got hot, so I took it back.

-took the radiator out and had it flow tested and flushed-no fix

Changed temp sensor that goes to the guage-no fix

(Yup, that's right, there are TWO temp sensors, one goes to the computer, one to the guage on the dash)(I didn't know that either)

-changed thermost-no fix

-told me that it now cools at high speeds and gets hot at slow speed

-Suspected either the guage was bad, or the water pump was bad.

Soooooooooooooooooooooooooo, with his recommedation that I change the water pump("You can do cheaper than I can) I picked it up this morning, changed the water pump, and TA-DA!temp guage does not go aver 210 degrees like it shouldn't.

Well Some Beach, first time I ever seen a water pump go bad that didn't also leak from the weep hole, but that's the case in this case.

Got to go see him Monday Morning to see what I owe him for the radiator flush, etc, etc.

Ahhhhhhhhhhhhhh well, learn something new everyday eh? On the bright side, I've practaclly a new cooling system. Coarse now the heater core will rot out.

Thanks for all the suggestions and interest. Some body actually said water pump, but I'll have to check back to see who.

Jack, change your water pump.

>Thanks Todd but I still think mine is electrical.Only reads hot sometimes. All week it has read perfect. Like it's supposed to.Sometimes for no apparent reason,the guage spikes and stays high for a long time then suddenly goes back down all by itself.I thought it was the thermostat at first but ruled that out a long time ago.

>Todd...I'm in the car business and I don't think you should pay for any of the repairs that did not fix your car. These "experiments" were the shot gun type of diagnosis. Any legitimate diagnosis should be paid for but unproductive parts and services were hunches not true diagnosis. At best only pay cost for the parts and split the labor. If you don't want to discuss this on the forum ping me off line.JR

>If you have an upfront complaint verified on the repair order and the fix didn't fix it,how can the shop justify the charges. Be firm...get nasty if necessary but don't let repair shops that hire low/no experience hacks rip you off. I have worked in this industry for over 30 years and I am tired of the negative image the profession gets because of shoddy work. JR

>It used to be so much easier when my Dad was the dealer. :)

I've found this great mechanic who's still not magic, so I give him a lot of slack on subtle problems. For example, the BMW, which is really getting long in the tooth but still runs so well, has a problem with recharging/starting. If I rev the engine when idling at a stop light and make sure to operate it above 2500 rpm, all is fine; but if I don't do that, after about 20 starts, it won't start, have to recharge the battery or apply jumpers. But the battery isn't all that low, just low enough that it won't start on its own. We've tried various fixes, nothing works. I keep paying the mechanic.

Same thing happens in so many situations. Say the doctor who misdiagnoses, the software consultant who tries to fix your system and ends up causing another problem, the woodworker who tries to repair a finish and ends up wrecking it, and so on. Leaving aside thieves, incompetents, and quacks, all these people work in good faith on tough problems and can generally not afford to do what they do for free.

>Hey Joe,

I really don't expect any problems with this fellow. I guess for one thing he is also from Maine. He runs a complete independant shop and is not in any shape form or fashion part of a chain, and that is why I use him. Just your basic small hometown shop here in te big city.

He was the one to recommend that I change the water pump myself to save some $$$$.

I have my truck, and as far as I know I owe him some $$$ for the cost of the radiator flush if nothing else. He knows full well that I'll return on Monday as agreed to work out the billing. Call it Yankee to Yankee trust if you will. We have known each other for several years now, and he knows my ethics. I'm sure that he'll be reasonable about the labor cost involved in chasing hunches.

One the other hand, I'llbe fair to him, as if nothing else I have damn near a full replacement of 10 year old parts that where bound to fail sooner or later anyway. The way I see it, this was just one of those cases where the solution defied reasonable logic, so with that taken into account............................

I have no problems discussing this "in public" as somebody else might benefit from the information that is put out. Thanks immensely for your concern Joe, it means alot, but at this point I have no worries. will report back on Monday ot tuesdat how it went.

Todd O.

>Good point Pam. No one should work for free. I just think a good tech should go the extra step in diagnosis before he charges for repairs.

Todd I admire your sense of responsibility. Your guy also knew that you had put the waterpump on recently. It would have been a poor choice to ask for that job. I hope you come to an agreeable conclusion. JR( and I'm glad your truck's fixed)

>How do you know whether the person you are dealing with is a thief, incompetent, or quack? I guess by getting a second and third opinion. There are several different types of garages out there. One has hundreds of thousands of dollars worth of diagnosis equipment and you pay for that. The other does not have the equipment, and you pay for that. I think it pretty much balances out. I ususally take my car to my brother-in-law, which has worked out well as he is certified but has very little equipment, and if he can't fix it we generally have to take it to the dealer.

>First couple of visits I ask them to explain things. If they can't or won't or generally appear evasive, that's a good enough sign that they're one of the three.

>Todd,

You've got the right attitude. If all the parts were original, they needed replaced anyway as preventative maintenance. You're lucky you didn't have a blown radiator hose out somewhere in no man's land and need an expensive tow. The question is why will original parts last 10 years or sometimes longer and replacements (made to OEM Specs)invariably seem to have half that life or less.

>"Made to OEM specs" usually means that it will fit. Does not mean that it is made of the same materials or to the same reliability standards. That is partly why some OEM parts cost a lot more, but are probably worth it. for other parts, it pays to shop just for price.

>Hi Pam. What's your driving style like? If you do a lot of short low speed trips combined with high elecrical loads (eg. heated seats on, rear window defogger on, etc), then what you're describing can occur.

I'm no expert, but I know that my VW has some type of load shedding alternator. My understanding is that at times of high electrical demand, the alternator lets the battery drain down rather that put an extra load onto the engine. The assumption is that most people drive long enough that the electrical demand will drop, and the alternator can catch up and recharge the battery. However, if you only do short trips, the alternator never has a chance to catch up.

The other thing that might be happening is a parasitic load, such as your trunk light never shutting off when the trunk lid is closed.

Just some thoughts...

Re: paying for shotgun

Joe Rogers, Northern Virginia

>Yes and yes. Both situations are very possible. Chasing parasitic loads is the current bane of my work life.

Pam, ask your tech if he has tested the electrical system for a draw. A difference of 15MA (normal)to 50MA could cause the problems you are living with.JR

>Wow, I learned something new. Parasite loads. Never would of crossed my mind about those. Did know about the short trip thing tho.

Last I knew it took 5-7 miles for the alternator to replace the charge you took out of the battery just starting the motor. Now turn on the AC, radio, and goodness know whatever else elctron eater there are in cars these days, drive for 3 miles, the battery is already behind, start 'er up again and drive home and shut off off, now the battery is really hating it.

Hope these suggestions cure your Beemers ails Pam.

>Yeah, I started leaving it running when going to the local stores and could keep an eye on it (I know, it could be stolen lickety split, but Austin is not Boston). Funny, I seldom drive more that 5 miles in one direction, and mostly only a couple of miles, no problems with the Vanagon so far. Cars are definitely finicky, what with all those electromechanical connecting points.

Yet something else to make you homesick

Bob Hackett

>I leave the keys in both vehicles every night and can`t remember the last time I locked my door either in the 5 years I`ve lived in this house or any of the ones before it.

Come to think of it,the last time I remember locking the door was when I lived in NY.That seems like a previous life.

I guess Maine may be proof of reincarnation.

Mainely,Bob-The only folks I know who lock things up are the ones "from away" who come up during the summer.They always leave us keys when they go back,I find that rather ironic.
