Hi bra.... new here from SA
My baby has been overheating... i took her for a pressure and combustion test. radiator and combustion in fine... what els could coz her to overheat... i think i need to replace to waterpump. anybody got instructions?

Howzit !
I'd suggest you check tuning etc. first - I had the waterpump replaced about a year back, 'cause it was leaking - it cost me R2400.00 ! Although that did include a new cam belt and camshaft oil seals. The water pump doesn't really break - the seals go eventually and then the coolant leaks. By the way, are you maintaining the correct coolant/water ratio in the system ??

okay... i is very new to all of this..
i know my water is not leaking out...
what do you mean... water ratio?
is it possible that maybe i need to adjust the tension on the belt?

By ratio, I mean there's supposed to be 40% Mazda approced coolant and 60% water in the cooling system.

Does your car overheat all the time, or just when you are in traffic? If it's just in traffic, maybe your fan isn't working ???

40% mazda approved coolant.... you mean antifreez..??
its only when i push her to speeds above 110km that the needle shoots up.. i can understand why?

Yup - antifreeze !

PS : Whatever you do, don't let her seize - an engine rebuild will cost more than she's worth !!!

thanks

Or maybe your thermostat isn't working properly ???

... lol.
i only got your note today...
yesterday i removed the thermostat... and poof. Problem solved.
she runs cooler at high speeds noe.... much better.

thanks for all ya help..

It's best to install a new thermostat - should only cost a couple of bucks at Midas and will allow your car to warm up far quicker when cold - cold running really speeds up engine wear, 'cause tolerances are set to work when the engine is at optimum operating temperature.

Hello,

I'm kind of in trouble : I am stuck with a big overheating problem, cant even do a mile without overheating... I guess the thermostat has got stuck closed. (I hope so, I dont want to pay a new pump).

I have very limited tools where I am and I have to work in the street.. (my other place is about 70miles away) so It would be kind if somewone could tell me exactly where the thermostat is and if I can whip it out quickly without a set of spanners.

Thank's all

ok, I figured it out first time

I found a decent set of tools finally and fixed the problem in a few minutes. (still managed to break an extention... very tight bolt there )

Thx anyway

Bye
