Re: AAP pump connected to engine vacuum directly

just cap the AAP you can live without it I agree. Mine are both disconnected and I only notice in winter when I try to accelerate quickly from idle for about the first 5 minutes of driving until the engine warms up a bit. I doubt it ever gets cold enough in Sri Lanka for the AAP to have a purpose.

Squealing belt info.

A few days ago my alternator/water pump belt started squealing at start-up/idle. It progressively got worse until it was squealing all the time. I assumed it was a loose belt so I checked it and it was properly tight. I replaced it anyway and it was fine for about 15 minutes and then it started sque...

Re: tt4wd runs to cool

I've bought several thermostats over the years. I've learned to ignore the name brand on the box and look at the name brand on the thermostat itself. It seems that the brand name on the box and the brand name on the thermostat hardly ever match.

Re: '88 Tercel automatic won't start....not even a click

There is a small wire going to the starter that is connected with a slide-on type (I don't know of a better term for it) of connector. Mine kept falling off and producing the symptoms you describe.

Re: Battery Corrosion/Brake Light on

Another check if you don't have a volt meter is to start the car and turn on the windshield wipers. Get an idea of how fast they move. Then turn off the car and turn on the windshield wipers again. They should move noticeably slower. If they move at the same slower speed regardless of if the car is ...

Re: Battery Corrosion/Brake Light on

When the alternator goes bad, the brake light comes on too on every Tercel (and old Camry) I've ever had. The difference is, the brake light comes on a bit dimmer than it would if there was a brake problem, if that makes sense. The brake light looks about half as bright as the battery light. If you ...

Re: Thermostat/cooling problem

I'm trying to wrap my head around how a radiator that's not pressurized enough can cause a too-cold cooling system. I always assumed it would cause overheating?

Re: Thermostat/cooling problem

No, no coolant loss. I haven't had the time to do much investigating this weekend, but maybe today or tomorrow I'll take it for a run on the highway and see if the temperature still drops with all the extra airflow across the radiator. If so, I'll just try changing the thermostat again.

Re: Thermostat/cooling problem

The reason I'm leaning towards a thermostat issue is that the temperature on the gauge drops to low gradually when I'm driving on the highway, just like as if there was flow through the radiator. I don't think a bad sender or gauge would act like this. I wonder if the spring is weak allowing coolant...

Re: Thermostat/cooling problem

I just used a laser thermometer to check temperatures in the cooling system. The temps started at around 35 degrees everywhere. As I idled the engine the temps very gradually warmed up everywhere equally (the upper hose/lower hose/radiator/thermostat housing/etc.). There wasn't the sudden temperatur...

Re: Thermostat/cooling problem

I thought about it being a sensor/gauge issue, but the flow through the radiator even at low temps is what is confusing me. I'm still going to check the wire run from the sensor and see if there is a partial ground somewhere. I might borrow a laser thermometer and verify temps as well.

Thermostat/cooling problem

I've been having a problem with the cooling system on my '81 sedan in the last few days. I was driving on the highway, when the temperature gauge started dropping like the thermostat was stuck open. It eventually went all the way to the bottom of the gauge. When I stopped at a light for awhile the g...
