Replying to: ort102 (Feb 01, 2008 8:29 am) I understand you have changed the thermostat.... ANd yes, exhaust invasion will impair coolant circulation but I'm still not committed to that explanation without further signs. WHen you use the heater DO you have a steady heat flow coming from the heater or are there times at which no heat comes?? Apart from hte needle that goes up, are there other signs of overheating? Steaming? One test I used to test gasket leak is applying compressed air to spark plug hole, after rotating the engine so the valves to that cylinder are closed. COMpressed air will try to push piston so it must be really at the top . IF there is a leak on one cylinder, the air will go to cooling circuit and bubbleup at the radiator cap.

Replying to: ort102 (Feb 02, 2008 8:18 pm) FOr diagrams, I can post some but better register yourself to www.kiatechinfo.com and grab everything you want first hand, diagrams, repair manuals, codes.... ANd I talked of compressed air as you use for tires but the more you say, the less I think you might have a gasket problem....and since you say heater works well, I have no doubts you do have water circulation which is rather difficult to observe from the radiator cap. HOw does the fan behave, specially just after engine is started: normally it runs with a whooshing noise for a few seconds then slowly clutches down... It might turn out all you have is a false temperature indication....and I wish this is the case....I'd try to use your kitchen candy thermometer in the radiator to have a 2nd temperature opinion....

Replying to: ort102 (Feb 03, 2008 11:57 am) I'd find an air compressor and test as I said. It is just so annoying the plugs are out of easy reach...but it is not such a tedious job anyway. You will have to remove the valve cover. engine THose complaining of fan clutch failure were mostly living in very warm environment and used A/C ; in cool temperatures, highway speed is sufficient even without a fan... Was the water pump changed at same time as timing belt (I think you said the belt had been changed...right). BUt Water pumps fail for bearings generally and that makes noise and leaks, not boiling.....

Replying to: lmp4 (Feb 03, 2008 5:54 pm) And do i have to take all that off just to give it a tune up??

Replying to: ort102 (Feb 03, 2008 6:03 pm) WHen you say "take all that off to give it a tune"...I suppose y0u mean the valve cover...hey?...well just to change the spark plugs, no. You would need to remove the intake tube and the plastic cover...and then you have the coils and the holes to the spark plugs..the plugs are hidden under down there and you grab them with a plug socket and an extension to your ratchet...  ..and possibly, you could apply air to the plug holes .. it is a long reach....but possible...but you would have some problem seeing which piston is at top dead center without seeing the cam position.... THe first time I had to do the spark plugs, I thought it was hell to have to do all of that just to reach the plug...and I still think the same...but in fact, a plug change can be done in just a little more than an hour...and with 8 or 9 extra 10mm bolts, the valve cover is out..and then back in. ANnoying, but easy and straight forward.
