1991 toyota tercel waterpump help Sign In

I JUST PICKED UP A 1991 TOYOTA TERCEL THAT HAS A DEFECTIVE WATERPUMP. THE GUY I HAVE WORKING ON IT SAID THE WATERPUMP IS TOO DIFFICULT TO REMOVE AND THAT HE'D HAVE TO REMOVE ONE OF THE ENGINE MOUNTS TO GET TO ONE OF THE BOLTS THAT IS SECURING THE WATERPUMP. ANYONE HAVE ANY FEEDBACK REGARDING THIS? I'M SURE SOMETHING AS SIMPLE AS THE WATERPUMP SHOULDN'T INVOLVE REMOVING AN ENGINE MOUNT SHOULD IT?

Some water pumps are a nightmare and some not. At a glance at this there is a high altitude version with more to do. Dipstick is in the way of either. Hey, it's a 1991 and if your mechanic just has to remove a motor mount to get the best shot at a nut or bolt or if that can help prevent breaking things then I suggest you let the person with it right in front of them decide the approach.

It's not uncommon to remove or have to just unfasten a motor/trans mount to nudge engine for best access to things. Breaking off a stud, bolt can make the simplest job a real problem. If you don't like this method your tech wants to do than find another but at the age of it I'd let him do his thing,
