Bonnet insulation

[Crocodile Gunn D]

The bottom of the "seat changing" thread runs on to bonnet insulation. In what way does this make a difference to the car? I'm not being sarky here, it's a genuine question.
I've had my car for 12 years, (it was an unfinished project at the time). I never refitted the lining as I was a bit paranoid about overheating. I thought that leaving the lining out would assist with keeping under bonnet temperatures lower, which it does, I also don't run a thermostat when I go abroad. I've been very happy with this arrangment. I'd appreciate other peoples veiws.

Hi

The insulation is only used as a sound barrier so if it's there or not is only cosmetic.



My concern is that you run without a thermo !!! - The Stag system is a pressurised system that requires a back pressure to the water pump to ensure you do not get cavitation within the pump itself (Air trap), this can cause a number of problems, wear of the pump blades and also reduced water flow.



would like to hear others thoughts.

Insulation could prolong the life of the paint on the bonnet maybe.

There should never be any reason to run a Stag without a thermostat. This has been used by dodgy sellers to try and camouflage an overheating problem, but not recommended for general use. If you find the car is getting too hot, then investigate why rather than remove the 'stat.

Firts thing to investigate is whether the car is actually getting too hot. Just because the gauge says so, it ain't necessarily so. Incorrect sender, faulty voltage stabiliser and faulty gaugecan all indicate a higher temperature than in reality.

If I had a Stag that indicated high temperature readings I would change the temperature sender fora correct one, not a 'will-fit' type. Then fit a solid-state voltage stabiliser. You can make your own for a couple of pounds or buy one off eBay.

Thoroughly concur. I had an 'apparent' overheating problem that eventually got solved by fitting a new temperature sender and the correct thermostat!
