Coolant problems, the sequel. FFS..

[ed]

Bad luck John, best of luck getting it sorted!

[Victor Meldrew]

Dan has a spare engine sitting that he is going to throw in if it turns out to be a problem with mine that cant be fixed in time for Donny.





















Wonder if its a Honda

[Rich H]

Its a 1.4 metro 8v engine... Didn't he tell you?
Bad luck
What was the diagnosis doc?

As long as he sticks on a turbo..

I hope that you get it sorted soon John what a nightmare

Spoke again to Dan this morning.

In the abscence of any combustion gas, (which we dont expect to find) were thinking along the lines of the PRT causing the problem.

There is some info about putting a restrictor in the by-pass to prevent starvation of the radiator at sustained high revs....

The first time the car overheated on me was at the end of the day on my Walshy day. For the last hour we were basically let loose to fcuk about on the circuit and I spent the time ragging the sh*t out of it as any good SE'er would do... it then proceded to overheat in a similay way as the problem I have now.. topped it up and bled the system and made it all the way home at a steady pace without issue. (familiar)

So Dans going to fit a restrictor or refit the std set-up...

Top bloke for coming up to collect the car.

[Victor Meldrew]

Dan picked up the car last night.. 2 hours from Newcaslte to Glenrothes.... hmmm.. in a Galaxy towing a trailer... thats shifting..

Didnt know his missus is expecting again, kind of explains why he can be a bit busy and hard to get hold of sometimes..

Surprised to hear that he had the time to manage something like that with the wife............



Congrats Dan.

Just pulled this off the internet. Maybe one of the guru's can comment....



You Might Be Thinking - How does this Remote Thermostat Work.

Well conventional thermostats open purely in response to temperature on the inlet side. As the temperature of the engine increases, the thermostat bulb moves to allow water to flow through the thermostat which permits the entry of a rush of cold water into the engine, and cooling it down.

The Remote Thermostat works differently, it slowly mixes the hot and cold water together, so when the thermostat finally opens fully, there is not a huge rush of cold water through the engine, which causes large temperature changes that damage the head gasket and cause it to fail.

The thermostat in addition to opening in response to temperature, also opens its value to allow a little cold water through to mix with the hot water of the engine, depending on the engine speed.

As the engine revs increase, the pressure in the coolant system increases also. In effect, this thermostat is predicting a temperature rise in the coolant system, as increasing engine speed means that the engine is producing more power, and more power invariably means more heat that the cooling system will have to deal with.

This opening is accomplished by a simple comparison of inlet and outlet pressure, which is achieved mechanically by a balancing spring. When the engine's water pump spins faster which is mechanically driven off the cam belt the thermostats inlet pressure is pulled down a bit and its outlet pressure rises. Therefore a pressure gradient through the entire cooling system develops and increases as engine speed increases. As the thermostat sits in the middle of that system, it sees a higher pressure difference as speed increases. In order to minimise pump inlet depression it opens at a set pressure drop, this drop setting is determined by the balancing spring inside the thermostat.

Well Dan has a 12mm restricor fitted in the bypass and is hopefull he will be able to get the car out for a severe spanking in the next day or two, its too wet just now to really rag the Shi* out of it.

Crossed fingers.

£3000 and its yours the 1.4 is a lot stronger having a differant block and someone has over 300bhp from one in a mini dont know for how long

Now then.... I did say my next project would invlove a bike engine with sequential box... didnt say anything about turbo though

[GregR]

Best of luck John, seems you're having no end of trouble with the motor lately

[Victor Meldrew]

Now what do you think happened next.

I don't belieeeeve it. Again.
