Hi Guys

Anybody tell me how to replace the thermostat on a 1995 4.0 Chimaera.

The "bible" does not give many clues how to do it, only the type of thermostat to use.

Any help would be appreciated.

Many Thanks

Richard

It's in the front of the inlet manifold above the distributor.

You'll first need to drain enough of the system to allow you to remove the top hose from swirl to stat, one end to swirl the other is the stat housing.

2 x 11mm's (or their imperail equivalent) for the housing. Awkward to get too and it sometimes helps to remove the dizzy cap to one side (leave leads on too save confusion later).

May be quite difficult to move away from manifold, if so a gentle tap with a rubber hammer will help loosen it off.

Check to make sure which way round the stat is so you know fo rth next one. Try and and ease away from the housing/manifold gently to see whether you can salvage the existing gasket.

If not hope you have a new one with your new stat. Also I like to put mine in with a little blue hylomar or similar to help it seal.

Make sure the stat sit's into the very slight recess it is designed to sit into.

I also drill a 3mm hole in the top of my stat if they don't have a bleed hole in them to help filling the system and with warm up.

Do not over tighten the bolts, they do not need to be 'f' tight and you risk damaging the manifold/bolts as they are ally.

Replace dissy, top up coolant and running up to temp to chekc for leaks.

30mins job.

10 - 15 minute job...it is at the front of the inlet manifold, just kind of behind the distributor and held in place by two bolts.

Have a look on ebay...you can get the thermostat on there for £7

I'm slick at this, but 15mins is really going for it even for me, only cos it's so damned awkward. Not now though for me, as I have no dizzy any longer hehe so 15mins more achievable !

Careful you get a panning of one of our southern members rofl

If you have a suitable 1/4" drive extension & socket it is easily achievable even with 2 casually smoked Dunhill International wink. .. but you need to go through the character building finger & thumbs twiddling exercise first to be a real TVR owner hehe

Hi,just a little tip when i changed mine.I put a couple of small dabs of superglue on the thermostat flange to hold it in place while the housing is refitted.With being verticle it can drop slightly out of the recess without noticing.Regards,Dave.
