an s5 TII engine with the water pump stoped (belt is loose), the engine was stoped for 2 years with no use. I started it and played a bit with the engine, reved it a bit hard but didn't full throtle it any time or reach the redline. never for periods of more than 5 minutes (maybe once but it was idleing). U think this may have caused enough heat to destroy the coolant seals?? the temp gauge never even moved.

thx in advance

 

Fix the water pump. Then pop the radiator Cap and crank it over see if coolant starts to come out the seals are bad. If not you should be good

 

How many 5 minute periods did you do and at what intervals? If you ran it for 5 minutes and shut it off and then did it 10 more times the car would have warmed up with no water circulating could have overheated it. If the temp gauge never even moved you have an issue unless you only ran it for 5 minutes and it didnt have time to fully warm up but still check to see that the gauge actually works.

 

I don't think it had time to warm up any of the times I used it.. it was pretty much like pure curiosity and that noise :p
I think I reved it only 3 times, and all on diferent days, and only one (maybe two) of those times I reved it a bit hard (+- 5 minutes periods each of those times)

 

wait so you reved a car with no waterpump for 5 minutes straight?

 

It takes 75 bucks and an hour of your time to replace the waterpump. Fix it, and don't turn the car on again until you have.

 

^ yeah...

 

hell I got lucky and bought a waterpump for 45
granted it was a shucks unit but hey lifetime warrenty reman and it seems to work for me so far

 

the car isn't mine. I didn't knew **** about Rx-7 when I did it. the guy at the stand only knew that it's alternator wasn't working and I didn't rev it for 5 minutes straight... I toyed with it for a while then let it be then I toyed with it again b4 I shut it down..
the water pump is fine, just has a loosen belt. that talk about replacing it leaves me thinking how many ppl read the whole post :\
