Toyota Starlet Radiator

Troubleshooting Toyota Starlet Radiator Problems

Despite its small size, the Toyota Starlet produces a lot of engine heat, so it's important that the radiator is in top condition to keep the engine from overheating. Typically radiators last for 8 to 10 years before wearing out, although this can be significantly shortened by infrequent flushing and maintenance. And once the radiator starts to show signs of wear, it must be repaired or replaced as soon as possible to prevent damage to the engine. So if you notice the following in your radiator, make sure to get it fixed or replaced immediately.

Leaks

Leaks are a major problem with Toyota Starlet radiators particularly in older models. Leaks usually occurs at the seals and the seams in between the radiator panels, as the epoxy that holds the seams together will start to get brittle and crack over time. Rust and damage from flying rocks and other debris can also cause a leak in the radiator. If you notice that the coolant reservoir is frequently running out of coolant or you see visible leaks on the radiator body, have the radiator checked, repaired or replaced as soon as possible.

Clogged radiator tubes

Another common problem with radiators is the buildup of mineral deposits in the small narrow tubes in the radiator core. These deposits come from rust and the use of hard, untreated water as coolant, and will eventually cause the radiator tubes to become clogged and for the radiator to malfunction. Coolant flushing usually fixes this problem, although extremely clogged radiators may have to be replaced.

Radiator overheating

The radiator itself is vulnerable to overheating and is due to a number of causes. If the radiator appears hotter than normal, turn off the engine and allow it to cool down. Check the exterior of the radiator for any signs of leaks. If the radiator appears to be fine, check the hoses and seals; a greenish or bluish-colored fluid on the hose or seal indicates a leak in these components. You should also check the coolant reservoir to see if there is enough coolant circulating in the engine and refill it if necessary.

  • Maintenance Tips for the Toyota Starlet Radiator 27 February 2013

    Because it is constantly exposed to heat and stress, the radiator in your Toyota will eventually succumb to wear and need to be replaced. But it is quite possible to keep wear at bay and get the most out of the radiator by taking care of it properly. With regular checkups and maintenance, a Toyota Starlet radiator can provide good, consistent performance for many years. And what's more, taking care the radiator is quite easy, as all you have to is to follow these simple maintenance tips:


    Make sure that there's always enough coolant in the radiator.

    Overheating is one of the main problems in radiators and is often due to lack of coolant circulating to and from the engine. Ideally, you should always check the coolant level in the coolant reservoir before you drive your vehicle. However, if you find yourself frequently refilling the reservoir, the radiator or one of its hoses may me leaking and needs repair or replacement.


    Check the radiator for leaks and damage.

    Some of the things you should look out for include wear and damage on the radiator body, particularly on the seams. The epoxy holding the radiator seams together tends to get brittle over time and might become a source of leaks. In addition, we also recommend checking for and replacing cracked radiator hoses as they can also be another cause of coolant leaks.


    Flush the radiator regularly.

    Radiator flushing clears the interior of the radiator of rust and buildup of deposits that can clog the radiator's interior tubes. Experts flushing should be done seasonally, although once every 2 years is often enough to ensure that the radiator's interior is free of obstructions.


    Don't use plain water as coolant.

    While it may seem like a cost-effective option, using tap water as coolant for your Toyota Starlet radiator will actually do more harm than good. This is because water can cause the interior of the radiator to rust which, over time, can eat away at the steel body and tubing and cause leaks. Tap water contains minerals that can build up inside the radiator tubes and restrict coolant flow. And since specially-formulated radiator coolants are becoming increasingly more affordable and are available in almost every gas station, there's really no reason for you to use tap water to cool the radiator barring an emergency.
