OK i have no history on this car i just bought it for cheap and the guy told me it over heats. He also told me he had just rebuild the head and bought a new block for it (B18A1 on a 98 :-( he showed me receipts. So i realized that the upper house gets hot and the bottom one dosent. So i changed the termostat and still no luck. Could it be the water pump there is no leaks but my car make noise like a rattle and i think its coming from the water pump. can any one help.
