    i have a 1995 daihatsu lhd jumbo with the 550cc and it was overheating because the radiator fins have fell out and i didnt want pay $300 for a original one so i got a geo metro one and im gonna put it in sideways because its to tall but when i was pulling the lower hose of the engine the fitting on the water pump broke the it still has some left what do i do? and what size hose does the engine have ?

    I do not know if you can put the radiator in with the tubes sideways, the cooler water is fed from the bottom of the radiator to the water pump and the engine. The warm water is returned to the upper part of the radiator then throught the tubes where it is cooled. I don't know how things will work with the water going from side to side. You may be able to get a hose on the remaining stub of the of the water pump inlet but you got to belive that there is some serious corrision in that water pump for the inlet to break off. Maby a new pump might be your best bet. It sounds like you have some serious corrision issues with the radiator heat sink material between the tubes and the water pump inlet going away, wish you the best luck in repairing.

    yeah and it would be to much work to put this radiator in so im getting a different one.does anyone know what the sizeof the hoses are?does anyone have a water pump?

    I have a problem with a radiator issue.
    So I swapped my old 659cc EFCS engine out for a 1.3l HC engine. Q: will my old radiator work for my newer bigger engine or will I have to get one bigger ?
    So I bought a new radiator that was meant for my new engine. But it's a vertical one instead of a horizontal configuration.
    My truck is a s82,& the engine came out of a s85. Now the space that's provided won't allow the new radiator to fit vertical. It's too close to the ground,& too high for my seats to to come down. I gotta make this new one fit because I spent over $300 for it with fan. Q: can I turn it on its side, and modify the fill hole with a 90or a 45° hose to get it higher that the top of radiator so I can get it to fit my space?
    Here is a example of what I have going on.

    I’d use a suitable one of these in your upper rad hose with a factory rated cap. And a higher pressure cap in the new rads existing location. I feel like it would still try to draw coolant or air in under vacuum from the side cap so that’s a problem.

    Do some searching around on how experimental airplanes with watercooled engines handle the problem of radiator installation. Years back when I was doing experimentals, quite a few used watercooled with oddly located radiators. I always used aircooled, so never dug into it much.

    the radiator cap must be able to avoid over pressure and vacuum. The cap regulates the maximum pressure, preventing damage to the hoses and radiator. After turning the engine off, the system cools and the coolant contracts significantly. The cap therefore has a return valve that admits air from the atmosphere or coolant from an expansion tank, if fitted. https://knowledge.northernfactory.com/en/articles/156-a-radiator-cap-serves-many-purposes

    I'm not sure if I'm following . I mean I follow about the function of the cap, but not how to relocate the fill hole,
    I tried to upload photos of radiator but the files were too big. So as before here is a diagram I drew with my advanced drawing skills.

    Well I guess the files my phone makes are too large for the site to process so no photos.

    The filler that goes in the hose, gets installed in you highest hose. Get a new radiator cap which fits the stock filler neck on the radiator which has a higher pressure rating than the one you install on the hose.

    If your new radiator has metal ends, and you have a radiator repair shop nearby, you could have them take the existing fill neck off your tank and braze it shut. And depending on your clearances, you might be able to braze a new filler neck or port on the new top of your radiator.

    I had Sunbeam Tiger back in my danger days, and the fill line to it was a 1/2-inch heater hose which ran to an expansion tank mounted on the fender. The expansion tank, had the radiator cap mounted on it. The radiator had three hose fittings, two to the engine at 1-1/2, & one at 1/2.

    Old school you had radiators made of copper and brass, which can be soldered. It was pretty easy to seal off and move existing hose ports and fittings, and to place things pretty much anywhere on either tank you needed them. Shops could desolder your radiator and add cooling tubes, or clean out your old ones in a day or two.

    If you have a pick-a-part yard near you spend a day wandering around looking at how different cars have solved the radiator issues. No shame in plagiarization in mechanic land, just in fuzzy subjects at school.

    To get your swapped system to actually get all the air out, you may have to mount some bleeders at high points.

    Well. I think I might just go back to my old radiator. So tell me this. Will my old radiator hold enough water to work on my new engine? Or is it going to be too small? Its going from cooling the 659cc engine to maybe working on the 1300cc.

    Maybe. Depends on how clean your old radiator is, and what you can do to increase/manage air flow though it. I’d try and see what happens. Other option would be to build a “roll bar”, and use it as carrier pipe for the coolant, and install a radiator on top, parallel to the roof.

    You could also install an oil cooler, to get heat away from the engine. The oil runs through the engine pretty quickly and will bring quite a bit of heat back to the oil pan. If you install a good oil cooler, with it’s own fan assembly, you can pull a lot of heat off the engine.

    Can I angle a radiator just enough for clearances? It doesn't have to be straight up and down does it?

    Most Shops won't install a new Motor without a new Radiator/Cooling System.
    With that being said the reason is they Won't warranty an old possible in adequate radiator.
    So if your doing your own work like I did Just make sure your Radiator is clean or I had mine
    Re Done with a new Core and completely refurbished as an older post showed pics and information.
    How much of an Angle are you talking about? I'm guessing a slight angle which wouldn't be a problem
    as long as the air flow is directed through the radiator for cooling! JMO!

    It's a new all aluminum radiator. Never been used. So when I bought it. They described it as being 13.75"×14.50". Well when I got it. It's more with the tanks bottom and top . Granted the top and bottom are shorter than a usual radiator.
    I'm talking maybe 90° angle. There is a fan going to be attached, after I modify it too fit the radiator. I had to order custom shifter ,and throttle cables because the old ones are too short. But without those installed. I can't really know what kind of pitch the radiator will need to be.

    Not have all the parts at once just makes things harder to figure out. If I install one part without the other just invites complications for fitting the other parts. So my angle is really not known at this point.

    Go ahead with your plans making sure your clearance is good and remember in hot weather when there's no air flow is when you'll heat up your motor faster.
    Like Jigs suggested an Oil Cooler would help out tremendously! If you don't have a Coolant gauge you might want to install one.
    It'll pay for itself the first time you notice your temp rising and you don't fry your Engine! JMO!

    I'm not understanding . I have the fan for my new radiator to draw in cool air so I don't think that's the issue. But to get it in and mounted . I'll have to angle it enough to make it fit. Now I don't see how an oil cooler will allow me to fit the water radiator in a slanted position,and function normally

    Without being there I can't Engineer it for you So this is where you have to get a little creative and do some design Engineering yourself!
    If you think about it it's a little similar to a race car without the team of Mechanics and Budget.
    There's different size oil Coolers so get creative on size and placement if you choose to dare.
    If your skeptical then just handle the Radiator angle on it's own and see where it takes you. It might work itself out.
    Keep in mind if you do decide to try the oil Cooler, which I highly doubt, placement will be important as to not block air flow
    in front of the Radiator.

    The right side of the truck right behind the cab, is where they mount the condenser for the factory AC. You should be able to mount one or both a radiator or oil cooler there.

    I wish I had ac. now something dawned on me ,I should run an oil radiator along with the smaller water radiator to compensate for it's small capacity on a larger engine. So if I do that . The small 660 radiator will on a 1295 engine?
