    When you replaced the header, did you also replace the tube bundle and all gaskets? The tube bundle is the copper heat exchanger, the headers are either plastic (capron) or cast bronze or iron. Did you also service and/or repair the governor assembly?

The header could be good while maybe the heat exchanger is warped. If this is the case it is due to abrupt temperature changes or a bad burn.
Might as well get a new heater if this is the case, but make sure to get to the root of the problem first so it does no happen again.

My raypack heater cycles on and off with a big bang each time it tuns on


It may be due to gas "pooling" before it ignites. Check that the pilot assembly is correctly positioned, and the burners and heat exchanger are clear of soot and debris.

Water is leaking from inlet/outlet area. is that a heat exchanger problem?


If there is a water leak in between the pool/spa plumbing and the inlet/outlet manifold, it just needs a new gasket if it is a plastic manifold, and if it is a cast iron manifold, the 2" threads for inlet and outlet need to be unthreaded, then coated with a pipe sealant (non-teflon) then rethreaded.

If this leak is in between the outer and inner inlet/outlet manifold peices, then a new gasket is needed. The part number for that gasket is: 006713f.

If the leak is coming from inside the cabinet and leaking down the interior or exterior, it could be a heat exchanger issue.

The most likely event is that the o-ring that seals the header manifold is worn and needs to be replaced.
This would take about 30 minutes of labor and an o-ring.

Please vote positively if this has helped.

Just replaced the water pump due to a leak not on it but behind the pump. I was told the leak was a tatle tale showing i needed a new pump. I still have anti freeze coming out behind it. any ideas?


The pump does have a weep hole in it. If a seal in the pump fails coolant will come out of the weep hole. Looks like you may have a bad water pump seal, but check gaskets, intake manifold and hoses as these can leak in this area as well. So determine where the coolant is coming from before investing in a new waterpump.

This is likely a leaking heat exchanger. These usually fail due to improper water chemistry. This can happen in less than a year if the chemistry is messed up enough. Most culprits are putting chlorine tablets in the skimmer and running the pH or Total Alkalinity tooo low. HTH

You need to buy the whole unit as these are pressed in place together. If you have a leak it is most likly due to chemical damage and goes further. So at the least you will need an exchanger. I will usually try to get people to go with a new heater if it is more than a couple of years old due to cost and hidden damage that can only come out after you install a new exchanger. Sorry for the bad news.

I have a 1994 Gran Marquis. Fuel lines are rotting and leaking


Just get a piece of the rotting fuel line so that you will be assured of getting the right size. Take it to a shop that sells car accessories, and ask them for enough to do your car. Also get new clamps. Start at the fuel tank, undo the clamp, pull off the old hose , put on the new one, do up the new clamp, and then just follow the old hose along, replacing it with the new one as you go. At the far end. do the same... undo the old clamp, put the new hose and clamp on. But I forgot to tell you about the fuel filter. Replace this while you are doing this job.

Is it difficult to change the governor in a raypack heater? I have the replacement (pool comp. confirmed old one was bad and ordered new one - company abandoned job - no other company wants to do work on...


It's not that hard if you can get the old plug out. This is located benith the water pipes and is a 2" plug. If you have a cast or bronze header (where the water pipes connect) It's simpley a matter of unscrewing with a pipe wrench and the thermal govenor just pulls out and slips in then put the plug back in. If you have a plastic header you unscrew the plug using a square shaft screwdriver or like pry bar, you can also use a large set of waterpump pliers most people won't have these on hand. The problem comes at this point the plastic will have a tendesy to stick to itself, meaning the threads will stick to the header and may stripp off when you unscrew the plug. If this happens you will need to replace the header. If your pool company abaonded the job this may be the case. If not you may want to take the whole header off and replace it from the back this is harder but safer. Good luck with your project.

1995 cherokee 2.5 td 150k miles will not start.


The oil pressure dropping to zero is common for cherokees. Replace the oil pressure sending unit and it will be good as new. Cracked exhaust manifolds are also common. Usually it will crack where the 2 pipes are welded into 1 pipe before it connects to the front pipe. There are lots of replacement headers out there to choose from. I just ordered one through quadratec.
