If the thermostat is operating properly the radiator will only come into play when the thermostat opens, when the engine is at normal operating temperature (around 190 degrees, give or take). Adding a gigantic radiator won't make a bit of difference because if the engine gets too cold, the thermostat will close, causing the engine to heat up again. In the ...

In the case where you run it too hot, you could start messing up your head gasket or warping the head itself. If you have to, in a warm climate, use distilled water or just keep replacing the antifreeze until you can get it somewhere, after which you'll have to have the whole system flushed. If you live in a cold climate your engine block could freeze and ...

Lets start with the fact that Ford doesn't make anti-freeze, they buy it in. It will have certain specs of course but so does all anti-freeze. It will also be made by one of the major producers of the product. If you can find the Ford specs you could compare it to other brands. Alternatively, contact the makers of different brands of anti-freeze and ask them ...

I would not recommend driving with an empty radiator, that could cause the engine to overheat as well as damaging the water pump.

I doubt the fluid is overflowing. You most likely have a leak somewhere. Common locations: The plastic container that you top off has a leak. (Check underneath it for puddles, also make sure the hose between it and the radiator is not leaking). Radiator (Look on the bottom for drips, it is typically behind the grill in front of the engine) Water Pump ...

First thing I'd try to figure out is how quickly it leaks - run it, stick your head underneath it as check if there is any visible leaking. If there is, chances are that it's not going to make it for 30 miles. I'd also check for any evidence of oil and water mixing. If there is, don't drive it. If it's not leaking that badly I'd be tempted to top it up with ...

I would definitely not intentionally put sodium hypchlorite bleach in my radiator. Vinegar is one thing, but the sodium hypochlorite will attack anything aluminum in your radiator, intake manifold, block, or head. It'll also attack (vigorously) any rubberized gaskets that're in contact with coolant. Even disregarding outright measurable damage, it'll release ...

Normally, I would ask first in a comment but that seems to be a privilege not available to new users, so here goes: Are you sure it was the radiator cap and not the overflow bottle? The radiator is usually full and getting 100ml in would be a struggle, not to mention that the green coolant would be staring you in the face. If you radiator wasn't full then ...

It depends on how much you are leaking. I've had a leak in a radiator and had to take it somewhere a few times, here's what I usually do. Fill the radiator completely full of water. If you can get it loaded, and it takes more than a few minutes to drain, you can proceed to step two. Drive slower than normal to your destination. Keep a spare gallon of water ...

The thinner radiator might make it easier for the cold air to flow through the engine compartment. (The radiator itself wont cool an already cool engine at all if the thermostat is intact.) In cold environments it is often necessary to use a grille cover to limit cold air flow to the engine. Grille covers are especially necessary with small diesel engines ...

Yes, it will. However, your biggest concern is going to be getting enough air flowing over it. Do yourself a favour and go look at the engine bay of a 200x model Subary Impreza WRX. The intercooler is mounted flat on the top of the engine and the characteristic scoop forces air onto it to cool the intake air. The same type of thing might work for your ...

I would not use that solution to clean my radiator. Remember that a radiator itself is primarily made of fairly thin aluminum. The bleach/vinegar could very easily damage the structure and weaken it. A washing machine is made of (in most cases) a steel drum coated with porcelain, or stainless steel, both of which are very sturdy and are made to last a long ...

A much cheaper option then towing, but which will ensure that nothing gets damaged, is for you just to fix the leak temporarily on the spot with some putty. I've seen cheap putty specifically for the purpose of fixing leaking radiators sold at many gas/petrol filling stations.

Antifreeze is a blend of several different ingredients: the antifreeze/coolant active ingredient, (mostly) water, corrosion inhibitors to prevent the water from rusting away the inside of your engine, and a secret blend of herbs and spices that's particular to each manufacturer. There are several different choices for the active ingredient (ethylene ...

If you are willing to drain the coolant, most radiators can be brazed or welded to fix pinholes.

The main thing the higher pressure cap will do is to increase the boiling point of the coolant slightly. 3psi isn't going to make a huge difference, but it will make some difference. If your cooling system is in good shape, the higher pressure unlikely to cause problems. If your cooling system is already on the way out, well, then it'll be on the way out a ...

I agree with Timo - if it is a big enough leak that you can see it clearly, then getting the car transported is much safer. In general, using water as coolant is OK for a short time or as a "get you home" alternative, but it does not have the anti-freeze and corrosion inhibiting properties of a proper coolant mix, so should not be left in the engine for ...

I think the main reason for this is convenience. It's an easy place to run the water pump. If you ran it out to a fan belt, it would be in the way of the timing belt while doing it, or it would be a really awkward mess trying to work around it. The second reason is for compactness. With the water pump stuck out of the way, it physically makes the engine ...

Engine safety. If you lose an accessory belt driven water pump, you're likely to keep driving, thinking the "oh, I just don't have an alternator" while you're busy cooking your engine beyond repair (normally with no temperature notification/change, if anything it'll read cold). When the water pump is on with the timing belt (or geared to crankshaft as is ...

You need to drain the coolant and replace it. You should follow the instructions in your owners manual. If you don't have one handy, the ehow page is a fairly general set of instructions but it'll get you into the right general location for the coolant drain. Keep in mind, engine coolant is toxic and should be disposed of properly. This is a perfectly ...

You can see the corrosion on the pipe around the clip - even if Radweld or similar is able to temporarily stop the leak, I doubt that it'll last very long. At the rate that it's leaking, there is bound to be a bunch of fairly sizeable holes corroded into the pipe. For that reason alone I would change out the pipe as soon as I could. If that breaks (worst ...

I can't speak for GM, but one reason they may be doing it is that they have a reputation for overheating under heavy use (heavy towing on the trucks and track days for the cars) amongst motorsports enthusiasts. Bumping it up a few psi is relatively safe for the cars and may well be enough to help keep the overheating under control.

With the improvements in modern antifreeze I rarely see radiator failures. Not that they don't happen, just no where near as often they did years ago. I think the crimped seal is more resistant to fatigue failure then the older brazed tanks were. Since aluminum can be expensive to shape and weld I am sure the reason for the change was a cost savings issue. ...

Straight coolant does not have the cooling properties of water. Straight water causes corrosion, freezes at too high of a temperature, and boils at too low of a temperature. The range to shoot for is between 50/50 to 70/30 Coolant/water

Firstly, you don't mention what car you have, which can help with diagnosis as we may be able to point you towards known issues with certain models. Bent or missing fins will cause the radiator to work less efficiently than normal, but that sounds like a fairly small area, so shouldn't be causing you a major problem. It is probably worth flushing the ...

How cold is it where you are? A lower radiator hose wouldn't do much for you as it doesn't hold very much water and water tends to not change temperature easily.

As long as you don't mix the two coolants together you should not have any problem. I run "green" coolant in my GM that came with Dexcool, and have been for more than 5 years. You do want to check the ratio of coolant and water as straight coolant (or too much compared to water) will not cool as well. To answer your question I wouldn't bother switching, if ...

The thermostat controls the temperature in the engine. It opens at a set temp, 195 degrees for example and allows coolant to flow through the radiator. If it's stuck open it would allow coolant to circulate through the radiator all the time not allowing the car to heat up properly. The complaint usually is the heater isn’t warm enough. If the thermostat ...

It's likely non-repairable, unless the vehicle is 15 years + old. The new style radiators are not cost effective to repair. A leak between the tank and the core, can usually be repaired, a leaking tank can usually be replaced. Core repair is difficult if possible, they are made so thin now it's next to impossible to repair. Check with a radiator repair shop ...

Late model Taurus do use a special coolant (usually orangish) which, unlike the standard biennial flush and change, is only serviced at around 90,000 miles or the kilometric equivalent. Use of common antifreezes (green and blue) will do damage. Use the recommended Ford coolant in the Taurus. You might have been advised to go to Ford for the obvious reason ...
