Probably best to have your pool guy do it. Unless you are a skilled plumber ... the liklyhood of collateral damage is pretty high on this heater. There may be other damage you are not seeing, like leakage into the electronics.

Why is replacement sprinkler head leaking?

If water pressure is over minimum recommended rate, your replacement sprinkler head shouldn't leak; it it's leaking probably because it is of a very bad quality. If it's new, return it to the shop where you bought it and clim your warranty right

Leaking screen wash bottle

You'll need to pull the bottle out to see where the leak is occuring. Look for

* split hoses from the pump(s). This is the more likely cause of the leak.
* pump O-rings. Remove and clean, and reassemble.

If the bottle itself has a crack or split, I've had success using a large 40W soldering iron with a flat tip to to CAREFULLY heat the plastic (often something like nylon) and effectively weld the split back together.

I am finding oil in the radiator.

This almost always means a bad head gasket or a cracked head/block, unless you are a mechanic this isn't something you are going to be able to fix yourself and is likely more costly to repair than the car is worth.

White smoke from under the hood

I would almost think that it's steam.
You might have a pinhole in a rad or heater hose.
It could also be a head gasket, or intake manifold gasket.

I havent started it since it froze not sure if it would do further damage.Is pressure testing something I can do myself ,like the ones autozone loan out.(the screw on the radiator type?)

hi, if you are sure it is no longer frozen then you can go ahead and try starting it if its no longer frozen you should be able to see if their are any leaks anywhere the most likely place is going to be the rad itself so have a good look around hear if you see no leaks and your sure it is no longer frozen then you can go ahead and try starting it you may be lucky and find you have no problems.

Freezing can cause the rad to split and leak it can also cause the cylinder head to crack and or the head gasket to blow.

So once it has thawed out properly have a good look for any water leaks check the coolant level if the level has dropped then you need to find out where this water has gone ie has it gone inside the cylinder if how ever the coolant level is fine then go ahead and start the car.

Let me know how you get on or if you need further assistance ok

The car keeps over heating and there is a crack peace

Engine overheating and coolant leaking...I would say there is a 99.999% chance the head is cracked. What most likely happened is the thermostat froze shut so the pressure built up so much that the head cracked.

You are going to have to replace the head, head gasket and thermostat. I recommend taking your car to a shop to have this done.

Pool heater leakage

Chances are that the header or manifold is cracked. usually the heat exchanger themselves are not damaged from freeze, but either the rear manifold (header) or the front header (the one that pipes go in and out of). Sometimes both. Replacing the entire heater is not necessary, about $200 in parts usually. We have a schematic diagram of the LJ heater here:

Antifreeze leaking into oil

Ummmm this is bad, you have one of two problems, if you may have a worped head or if your car froze up recently you could have a cracked engine block. Go back to the mechanic that replaced your gasket as he may of not replaced the head gasket properly
Hope this help
