Thermostat Replaced big difference noticed.

[steve2006]

For some time I noticed that my temperature gauge was not reaching its normal halfway point, this was more evident on a longer run on a motorway when it barely moved from cold. I also found higher fuel consumption.

After my failed attempt to purchase the parts from Amayama I obtained the genuine parts from LPD ( thermostat, seal ring and 5 litres of red coolant) and went about the replacement.

Easy enough to do and the change was immediately evident in the much quicker warm up time and the gauge once again steady at the halfway mark.

A post mortem on the old thermostat soon revealed the reason, the rubber seal on the thermostat itself had perished and begun to break up allowing coolant to pass when closed. This would appear to tie in with the previous symptoms of a long warm up time and constant over cooling.

The old one looks original so not done bad over 26 years and the missing section of seal in the pictures fell off on removal so hopefully nothing has entered the coolant system which could cause problems.

Not a general service item but may be worth checking given the age of these cars now.

It would definitely be great if you were living close when help is needed.

Oh.......I'm sure that, if you were willing to send a return air ticket and arrange accommodation, Steve would be more than willing to help.  😁

That would be excellent. Only thing is that we have a rather new lexus and with the reliability of these cars such help would hopefully not be needed the next 20 years.  😂  😷  🤩

When it gets to this temperature just book it, Radisson Blu at Puerto Mogan will be fine for a couple of weeks 😀

We live in Las Palmas up north. Have skin cancer so do not go out in the sun. Before finding out:

 

2000 m up in the air, above the clouds. Probably where the skin cancer came from.

Sorry to hear that John, I do like the heat but always sit in the shade especially on the beach and of course factor up.

Fantastic bus service on the island even better since they built the new road through the mountains to Mogan, the old cliff edge road was a bit scary.

That is true. The new road is faster and more secure, but I do like the old road with beautiful sea on one side and mountains on the other. Fun to drive there in the MR2 Spyder and Smart Roadster Coupe. Really a place for go-carts.

But top of the mountain is beautiful. No tourists and peace and quiet. I miss it.

 

Fresh air and funny trails.

If safe to do so...run with the auto air on system off for a short time.

The needle will soon point to a warming engine...then all can be switched to auto...

Fastest way to warm up engine.
