coolant problem

[thejum57]

Last weekend I replaced upper & lower radiator hoses. I did the heater hoses too. I didn't replace the thermostat. This weekend I did. I still have the same problem that made me want to replace the thermostat....the top radiator hose is hot...the bottom one is not, either are the 2 heater hoses. When I filled it with antifreeze, I had the heater running, and the engine. Any sugusstions??? Thanx :cheers:

 

BTW, it's the 2.5 liter engine

Sounds like the radiator is clogged to me.

:agree:

Ouch....do you think flushing it might help...or is it death to the radiator??? Is it ok to drive fairly short distances? It's about 15 miles to work.

[BLHTAZ]

You could try a flush, but if it's blocked that badly, it may not do any good. I would be afraid of driving it that far...a short distance would 5 miles or less. These engines achieve operating temperature within just a few minutes so 15 miles would probably be trouble if the problem is what it seems.

Unless the radiator is too far gone, a radiator shop should be able to clean it out.

Well, today I disconnected the bottom radiator hose, let the radiator drain & ran the hose thrugh the cap. The water came thrugh pretty good & clean. So I re-connected, filled the radiator and....same problem...only the top hose gets hot. Time for the pros! :mad:

Not if you buy a one-row radiator with plastic tanks.

 

Just a longer way to spell J-U-N-K in my opinion.
