Belt, hose, leak, coolant system repair in GAINESVILLE HAWTHORNE BY ECONOMECHANIX

Bad belts and hoses can hurt you!

Suppose you knew there was a ticking time bomb under your hood. Would you keep on driving until it went off?

Although a blown radiator hose or broken belt won't kill you, it can certainly strand you in the middle of nowhere. (In these violent times that might just be a matter of life and death!) On some cars, this COULD DESTROY YOUR ENGINE: an expensive proposition indeed!

Rubber goes bad with time regardless of mileage. Any car which has over 5 years or 50,000 miles should have all belts and hoses replaced.

Bad belt symptoms and diagnosis

You should inspect your belts regularly: a good time is when you change your oil. Before you go on a log trip it's a good idea to look at your belts. Look for cracks on the inside of the belt: if you find any, replace ithe belt.

Types of belts

Most cars have either a single serpentine or multi-groove belt, or multiple "vee" belts. The serpentine belt is flat with 3 to 6 grooves. Most newer cars have this type of belt. The older style "vee" belt is narrower and thicker, and has a "vee" shaped cross section. Some cars have 2 or more serpentine belts, or a combination of "vee" and serpentine belts.

Belt service

Most newer serpentine belt equipped cars have a spring loaded belt tensioner and no service is needed besides replacement when cracks develop. Other cars, and all "vee belt" applications, may need periodic re-tensioning of the belts. The most noticeable symptom of a loose belt is a squealing from under the hood, often while parallel parking (loose power steering belt), or when you turn the A/C on (loose air conditioner compressor belt).

Bad Hose Diagnosis

The second most obvious symptoms of bad hoses are spots on the ground and a constant need to add fluids. The MOST obvious symptom is smoke pouring from under your hood as you stand by the side of the road waiting on a tow truck.

Before any of these symptoms occur, bad hoses develop cracks, and soft spots. Like all rubber stuff hoses don't like oil, so examine any hoses that have gotten oil on them carefully. If oil is getting on a hose, clean it off. This is one good reason for keeping your engine clean. If a hose has gotten "oily" clean it off and feel it. If it feels softer, or even just different from the rest of the hose, REPLACE IT!

Look at the ends of the hoses, especially the "engine" end. There should be no swelling behind the hose clamp where the hose connects to the motor. This is where a hose often fails.

Color Coding

If you see spots on your driveway the color can tell you what's leaking:

GREEN, ORANGE, OR RUSTY WATER means an engine coolant leak.
DARK BROWN TO BLACK SPOTS are engine oil leaks
RED TO BROWNISH RED SPOTS are transmission fluid leaks
NOTE: Front wheel drive vehicles and many others have rubber transmission cooler lines which can go bad: look for cracks and leaks at the connections
RED, AMBER, DARK GREEN spots can be power steering fluid

CLEAR WATER can leak from under a car as normal operaton. The most common is the air conditioner: it can drip out an impressive amount of water. Some body panels on a car have drain holes: rainwater can drain out of them for a few minutes after you park.

A CUTE WAY TO CHECK FOR LEAKS

Not sure if a spot on the driveway is your leak? here's a cute trick to find out. Order a pizza. Eat it. Unfold the box and slide it under the car, clean side up. In the morning remove the box: look for spots.

One advantage to this is that you can open the hood, lay the box across the engine compartment, and look straight down from the spot to locate a leak. The same applies if you have to crawl under the car: the pizza box is your "map" or "x-ray" of the leak location.

Oo-o That Smell!!!

Many fluids can be diagnosed by smell. 90 wt gear oil (used in some manual transmissions) looks very much like engine oil, especially when it's spread all over the underside of a vehicle! The smell, though, is unmistakeable. 90 wt gear oil has a very distinctive smell.

You can use this to diagnose a leak on your car: if you "don't know what to sniff for" you can get a sample easily enough:
Engine oil and automatic transmission fluid sample at dipstick tubes

Coolant sample at coolant recovery tank or radiator cap ON COLD ENGINE ONLY!!

Thank you for visiting the ECONOMECHANIX WEB SITE. Please feel free to comment. We also serve the surrounding communities of Alachua, High Springs, Hawthorne, and Newberry! Gainesville has been my home since 1974, and I've loved Gvl and the Gators since I came here in the fall of 1974 to attend the University of Florida. I loved it so much I stayed and opened my car repair business. Originally it was out of the back of a 1963 Chevrolet wagon, but in 1977 a fellow mechanic and I opened an auto repair shop with actual walls, etc. I stayed in the same location for 26 years, and recently moved my operation to property I bought 15 miles east of Gainesville. I am doing most all the repairs myself now, having reduced my overhead from $1500 per month to practically nothing. I do work by appointment only. I mostly work only on my established customers cars, but I will occasionally take on new clients. E-mail me and I will either make arrangements to look at your car, or I will recommend you to someone who will.
