Every radiator cap has when you look at the inside (part that you put onto the radiator there is a number IE: 15 18 etc) This is the correct pressure you need for your vehicle any vauxhall garage will tell you what pressure you should have on your vehicle, buy one from them they are not expensive even from the Vauxhall garage Problem solved. Hope this helps Best wishes, Malcolm Campbell.

How do you put radiator in 1999 hyandai accent


1) Drain radiator by removing cap, and bottom radiator drain bung or bottom hose.
2) Remove top hose.
3) Disconnect the radiator fan's wiring and any temperature sensor wiring if fitted.
4) Remove radiator retaining clasps
5) Disconnect radiator bottom hose.
6) If fitted with an auto box, then remove automatic gearbox oil pipes (Underside)(you might wat to clasp these so they don't leak oil everywhere)
7) Remove radiator expansion bottle feed pipe from top of radiator.
8) Ease out the radiator. If the radiator fan is getting stuck or caught up, then drop the radiator back down and remove the fan first after disconnecting from the radiator body.
9) With new and old radiator placed side by side on a soft surface, change across any components from the old radiator, which didn't come with the new one. These may or may not include such things as: cap, fan retaining screws or clips, bottom radiator seating rubbers, rubber fan shrouding, temperature sensor, top and bottom rubber hoses.
10) Rebuild by reversing the above instructions. Apply silicone pipe sealant to top and bottom hose locations. Make sure you clean and/or replace any heavily corroded metal pipes which connect to the radiator. (Now is also a good opportunity to replace the thermostat to be on the safe side)

11) Fill system with a fresh 50/50 water/antifreeze mix, flush out and refill expansion bottle. Just before you refill the system, turn the interior heater setting up to maximum heat, but do not start the vehicle.
12) Top radiator up to max. Gently massage the top radiator hose to help eliminate air from the system.
13) Once filled, start the car. Pay attention to the temperature. Keep topping up the radiator as bubbles come around the system and the coolant level drops. At the point no more bubbles appear, close off the radiator with the cap. Allow the engine to reach normal operating temperature. If the weather is cold you may want to hold the engine at around 2,500 revolutions to help build heat faster. Keep it running until the radiator fan kicks in, then let it idle for a couple of minutes.
14) Stop the engine and let it cool.
15) Once cool, open the radiator cap and top up again if level is low.

16) Road-test the vehicle. After returning check again for any leaks.


Running the car for the first few days after radiator replacement, check the radiator level and expansion bottle level every day for the first two or three days. This level may drop slightly as any trapped air pockets are pushed out while running. Also, it is possible that any small leaks may begin after adding fresh anti-freeze to the system. If you begin loosing fluid over these first few days, then re-inspect your work and run a cooling system pressure test.

Upper radiator hose keeps leaking coolant, replaced the cuff ring but still seems to leak after a few days from the cuffed end of the hose. Does it need a new hose?


if it is leaking where it connects to the radiator it might be the radiator itself. take it to a shop and they can pressure test. some shops won't even charge for test.

My rig is a 1991 Ford F250, auto, 4x4 with a 460 engine. I have a antifreeze leak somewhere above my oil filter. I think it is coming out of the silver box that my bottom radiator hose goes into... but I...


Is that silver box by chance the water pump? I would imagine the small hose is for the heater ... The big hose goes in, that's where it would draw in the water/coolant mix.

I have a 2001 Saturn SL2. The air conditioner only blows warm/hot air. I don't know if this is related, but the car also has a leak around the radiator. It constantly needs to be filled with...


No, these problems are not related. The radiator is a sealed system and you may have a leaking hose, bad water pump or the radiator may have developed another hole in it.

The A.C problem is one of three things.

1. The A/C Freon has run out of the lines. This is a fluid used to maintain cold temperatures and produce the cold that actually comes out from your vents. It could be as easy as recharging the A/C system.

2. It could be the high pressure line that feeds the freon to the system. This would require replacing the hose and recharging the system.

3. It could be the A/C Compressor is bad and need to be replaced and the system recharged.

Each of these are progressively more expensive and should be fairly easily diagnosed, albeit by a automotive professional. I would not suggest you try to fix this yourself.

Leaking coolant from around water pump just put in new radiator on monday and no leaks from it or hoses, think is weap hole in bottom of water pump.


If it's the weap hole the pump is going bad. That hole is designed to leak as a "warning" that the pump is going to fail.

Radiator hose 93 chevrolet cavalier not sure if it is upper or lowerthe one cracked comes out of bottom of radiator so i assume it is the lower


depending on how many miles you have on the car i would look at the lower hose first; the other common problem on a 93 cav would be the lower radiator neck or radiator leak; the lower hose has less pressure on it than the upper so sometimes finding the leak can be tricky. with the engine off and cold squeeze the lower hose by the radiator to see if any fluid comes out. otherwise you would have to pressurize the system to find the leak

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.
