Re: New engine running hotter

The engine is running good now. Has 83K on it. Compression is 175 175 175 175.
I was all set to adjust the valves, but they were already 008 and 012.
There is a puff of white smoke in the morning, so I bought some valve stem seals at Rockauto.

Re: New engine running hotter

New thermostat fixed it.
The cooling system seemed to be working OK with the old one, but it ran just a fraction hotter when it was warmed up.

New engine running hotter

I just installed a newer 3A engine in my SR5, and the temperature gauge says it is running hotter than the old one. I set the timing to 9 degrees BTDC. I purged the cooling system and it has probably 60/40 distilled water/antifreeze. I am using the temperature sender that came with the engine, but I...

Do you use a load balancer when pulling engine?

I am prepping an engine swap and I was planning on renting a load balancer to adjust the engine angle. But since a line between the engine hooks isn't parallel with the crankshaft, adjusting a load balancer is also going to shift the engine left or right. Does it work anyway? What is the best way to...

Re: Thoughts on how to wire up a TEMP warning light?

This is a Comparator Module that I bought on ebay. It is available from many sources, with a few types of connectors. I got this one with terminal blocks (which barely accept 18ga wire). The circuit board should say DT-110. I already had a wiring harness hooked up for the one I made, and I connecte...

This is how the module is hooked up.
I'm using the triangle as a symbol for the whole module, which includes a LM393 comparator and some other components.

(see the description for op-amp voltage comparator)

Re: Thoughts on how to wire up a TEMP warning light?

But after I started on this project, I found out that you can buy modules based on a similar chip.

Re: Thoughts on how to wire up a TEMP warning light?

I am using a LM311 chip, A 2N3906 transistor and a relay*. Setting the trigger point is done by adjusting a multiturn trimmer potentiometer (aka "pot") I also wired up a 50 ohm trimmer pot in series with a 20 ohm fixed resistor. To set the trigger point, I disconnect the sender connector at the engi...

Re: Thoughts on how to wire up a TEMP warning light?

I wired my project up to Ground, switched 12v and the wire that goes from the sender to the gauge.

Instrument voltage limiter

Does the 4WD Tercel have a voltage regulator or voltage limiter for the gauges?
I don't see one in the wiring diagram.

Re: Thoughts on how to wire up a TEMP warning light?

BTW the TEMP light you are talking about on a Tercel is actually for automatic transmission equipped cars and comes on when the transmission is too hot. Normally. that would be true. But we are talking about adding an Idiot Light in addition to the Temperature Gauge, to remind the driver to look at...

Re: Thoughts on how to wire up a TEMP warning light?

Is reading the temperature somewhere on the exterior of head or the block as good as reading the temperature of the coolant directly? This thing was originally designed for another application and then modified to to be used on cars. I originally was attracted to the fact that it didn't require a se...
